Side by Side Comparison of: Philips vs Cable Matters vs Monoprice vs Philips Computer Monitors

I received two of these monitors this morning, and am writing this review after just one work-day with them.I jumped into 4k a little over a year ago with 3 Samsung U28D590D, 28" displays. They are wonderful, but I knew pretty quickly that 28" was not enough, as I had to use Windows Scaling to be able to read. I drug my feet on most of the 34 inch displays because of cost.When I saw this display I researched it extensively and read reviews and decided to take the plunge.Setup and install was simple, but there is no easy auto-run on the CD, so use Device Manager, find your monitor, then tell it to update the driver and point it at the CD.Be sure to change the monitor's Display Port setting from 1.1 to 2.0 if you want to get 60hz (toggle-button right, then down about 7 times).For a while the first display kept going black, saying there was no input, then coming back to life at only 30hz. I researched this and found many others having this issue. Eventually I replaced the [old] DP cable from my previous monitor with the one included with this, and the problem went away.-----I'm a programmer, so I want lots of real-estate for my dev tools, VMs and research materials. I can't tell you how perfect these monitors are for that: everything is crystal clear with no Windows scaling.Color is vibrant and full, response times great. I tried some gaming to verify that there was no screen-tearing at 4k and found none (AMD R9 280x).-----The only down sides are:1) They're so big, my desk can only accomodate 2 :-)2) Beware of maximizing a window; it jumps SO large it will startle you :-)I highly recommend this display.I generally write reviews soon after purchase, but will update if I find any issues.---UPDATE 2/23/2016After having these monitors a while, the only [very minor] issue I've found is that either they--or my graphics card--cause the displays to flash off and back on a couple times when I wake from sleep. Not a real problem, but as it didn't occur with my previous 4k monitors, I'm betting it's the displays and wanted to mention it.I've now done a little bit of everything with these, and found them perfect for all of it. My workflow has changed in many of the tools I use because of the vastly expanded screen space and my productivity has improved as a result.I highly recommend Toms Hardware's review on these displays, particularly if you have banding or visual artifacts; proper adjustment is important for good performance.

As a programmer, I'll second (and third, and fourth) that making the switch to 4K is something you'll do and you'll never go back.The visuals/brightness/colors are just fine on this monitor for programming. No bad pixels, and supports the full 60 Hz 4:4:4 (with sufficient graphics card) which would be my only concern along those lines.One thing worthy of note: At first I assumed I'd be using this monitor for programming by placing many application windows on the screen at the same time - kind of like 'FOUR 1920x1080 monitors in one'. I even tested different window manager programs, and went with WinDivvy (it's great - simple, and works so that with a single key combination you can pop any window to any size / position).However, quickly I shifted into my current mode of work: With the 4K, I now use the monitor in PORTRAIT mode, and only have ONE application window showing at a time, filling the entire screen. Yes, that means that I still have as many Alt + Tabs as I did with my 1920 x 1080, but you can fit an INCREDIBLE amount of vertical text on the screen with a 38040 x 2160 in PORTRAIT mode. Just a few Page Up/Page Downs can navigate through an entire thousands-of-lines source code file.Seeing so much code on the screen at one time makes the mental effort SO much easier. I recommend this monitor in PORTRAIT mode for programmers.You'll need a good monitor arm mount to make any real use of this monitor, so be prepared. Here's the one that works great: http://amzn.com/B00GN4DCR0... and here's my review for the above monitor arm: http://www.amazon.com/review/R1FHPPX0ARTT1C/ref=cm_cr_dp_title?ie=UTF8&ASIN=B00GN4DCR0&channel=detail-glance&nodeID=541966&store=pc&tag=storiwrittbyl-20

Read the reviews and they will help with the set up. I purchased this 3 days ago and I have worked 8 hours a day all 3 days on it. I have windows 10 installed on my Surface Pro 3. I have been running 2 27 in monitors and wanted a bigger screen to better take advantage of Windows Snap for putting mulitple programs on your monitor more easily. This is essentially like have 4 20 inch monitors. Totally awesome. No dead pixels or other issues people have mentioned. This thing is beautiful. I was worried that it would look monstrous on my desk but it really seems fine. 40 inches is the perfect size for 4k monitors. I am a CPA and primarily use it for spreadsheets and such. Snap makes it easy to snap 2 spreadsheets side by side and work way better than having 2 monitors. This is about as perfect as it gets. I highly recommend it.

This is literally the ULTIMATE monitor for computer professionals (I have software engineering in mind as that is my profession, but this applies equally to anyone else who uses computers extensively in the office). I have never enjoyed a monitor for work more than this.I have two Dell U3014 30" 1600p monitors at work, and am seriously considering buying one of these to replace them. It's an incredible deal, if you think about it. Each Dell U3014 costs ~$1100, making two of them ~$2200. For just $800 for the Phillips, you get more pixels, more screen surface area, and overall a much better experience since it's just one continuous panel, and fills your field of view more naturally.In terms of display quality, I have absolutely no complaints. I understand that generally good IPS screens can have better color quality, but I honestly don't notice anything worse. In fact, the VA panel of this monitor actually looks better overall to me, since IPS screens have a notorious inability to display deep blacks (they look a dark gray glow instead). That makes this monitor also excellent for movies and video games.

Finally, a worthy replacement for my venerable old Dell 30 incher.As noted in some of the reviews here, the default video setting was a bit washed-out, but there are plenty of calibration tools and helpful websites to get it looking truly incredible. The box came with a lot of cabling, but (oddly enough) not the two cables I needed. Okay, I guess I can see including an HDMI cable, but a VGA cable? How retro. Audio cables were included, but unless you hate your ears I trust you will have a decent sound system and/or headset already. The two items that were not in the box were a DisplayPort cable and a USB 3 cable to run from your computer to the monitor's USB 3 hub. Not a deal-breaker since I had a spare DisplayPort cable and a quick run to Radio Shack and 7 bucks got me a USB 3 cable, but a strange omission to leave out the ideal connector.After getting calibration done, setting the monitor to DisplayPort 1.2 input mode, and changing the refresh rate to 60hz in the nVidia driver (after a moment of panic before I realized I had to scroll down to the PC section of the list and choose 'native' since the only option at the top of the list was 29hz) I fired up some games that would tax the system. Happily my GTX 980 has handled everything I currently play just fine.As long as you're aware that you may need to shell out for some cabling and there may be some tweaks needed, this beast does not disappoint. It's not worth knocking half a star off because this monitor absolutely delivers where it counts.

Great picture, performs well. Fixed stand might have been a bit of a problem, but I've got it mounted on a flexible wall mount. The USB 3.0 cable was a bit short, replaced it with a longer one.BTW, these do all have speakers, but they are very poor. I don't THINK anybody buys these for the speakers, but be advised that you're going to disable them as soon as you install the device.

I have only had this cable for a few days, so I cannot attest to its longevity, although I had no problems using it to connect my Surface Book (via the new Surface Dock) to an HP EliteDisplay E241i at 1920x1200. I have not tried using it for 4k output, as I am not yet on that bandwagon due to the lack of truly universal DPI scaling, even in Windows 10. I will say though that Win 10 does do a MUCH better job than previous versions when it comes to maintaining scaling on a per-display basis in multi-monitor situations where HiDPI and normal DPI displays coexist. Quick tip for Surface Book/Pro users using the docking station to connect to a monitor using 1:1 scaling: if some elements are still scaling up on the additional screen, simply log off/on, and this should correct the problem on the additional screen. Alternatively, hook up to the docking station before waking from sleep or signing on. I personally like to set the external as my main display, tweak the power settings so that the SB does nothing when the lid is closed, and then set it aside (lid closed), resulting in a traditional desktop-like setup. Throw in my Logitec MK270 keyboard/mouse combo (which also work flawlessly in this configuration) for around $20, and I can be every bit as productive sitting in my bedroom as I am at the office.

As I type this, I am using two of these cables to connect my MacBook Pro Retina (15", Late 2013) to a pair of Samsung U28D590D monitors. Both displays are running at full 2160p resolution (3840 x 2160) at a full 60 Hz. Absolutely LOVE this cable!

I just purchased an ASUS PB278Q 27-Inch WQHD LED-lit Professional Graphics Monitor and wanted to connect my 2011 Apple 15" Macbook Pro and 2011 Apple Mac Mini. This cable works without any issue and is literally plug-n-play at the display's full 2560x1440 resolution. I am very pleased to know that I don't need the expensive mini Displayport to Dual-Link DVI adapter to drive the Asus monitor. All I need is this cable. It even carries sound to the monitor.

I bought a late 2012 Mac Mini with an Intel i7 processor and then installed a SSD to speed it up even more. So, all that was left was to get a display running at 2560 x 1440. I decided on the Samsung 27" LED S27B970B monitor capable of this resolution. Once setup I realized that HDMI would not give me the resolution I was looking for. I learned that I needed to use the Thunderbolt connection on the Mac and the Displayport connection on the Samsung monitor. Well, Thunderbolt is essentially a mini Displayport; this cable turned out to be the perfect solution - mini Displayport to Displayport. I am typing this review while enjoying my new 2560 x 1440 resolution. Don't settle for some other type of solution (I'm told perhaps a DVI-D would work, but why use an adapter and cable when you can just use a cable) - this is perfect and CHEAP! Time will tell if the cable holds up, but I suspect I will not have any issues. If I do, I will update this review.

Hooked up my U2317HM and couldn't get it to work at highest res with any of the other hdmi, dvi, vga cables I had.Read another review and 2 days later it arrived and 3 minutes later I was at 2560x1440

I use this cable for my Dell U2711 PC monitor. The cable has no difficulty with the native 2560x1440 resolution of the monitor, despite the description stating up to 1920x1200 resolution. The 15-foot length allowed me to be more creative in placing my CPU further from the desk. DisplayPort conveys a digital signal, so it doesn't make sense to buy a more expensive cable - for the most part, a digital cable will either work fine or it will demonstrate immediate problems, with nothing in-between. I was happy that this cable met my needs perfectly.

I did a LOT of research before purchasing this monitor, and I have been very satisfied with the selection. What I needed:- 3840 x 2160- 60hz refresh at full resolution- Multiple digital inputs - 2 DisplayPort or 1 DP/1 Mini-DP- A price that didn't look like a Range Rover monthly payment.I may play a game now and then, but this monitor is not primarily used for gaming, so I can't speak to its performance in that arena. No dead pixels, and no issues with setup. It's being driven by an ASUS STRIX Geforce GTX 980 TI.There are situations when some horizontal ghosting is apparent. The circumstances have to be just right, but if they ARE just right, you will see those horizontal lines. Now, I am VERY picky about things that have the possibility of visually annoying me, and was very concerned about this. However, it really hasn't been an issue.There is ZERO adjustment possible to the physical attributes - tilt, height, etc. The one annoyance I have is that there is a slight tilt back when mounted. I actually considered getting a VESA mount because of this, but decided that it's more trouble than it's worth.Summary: Some flaws, but no deal-breakers. Great value.Important note: Out of the box, the monitor is NOT set to use DisplayPort v1.2. You will only get 30hz refresh rate until you change that in the setup menu.

Having a 40" monitor is awesome and I like it much better than a 2 screen setup. If I were to get another 4K monitor I would go with an IPS panel though. PIP is great since I have a work and personal laptop so being able to peek at personal stuff without having to use remote desktop is great. I wish for 2 way mode they allowed the screens to take up the full horizontal or vertical portion, but it's basically like each computer only having one 20" 1080P screen instead of taking up. That said, no dead pixels and a great monitor for the price.Pros:4K2 HDMI, miniDP and DP hookups (and VGA)PIPMenu knob is odd to get used to at first, but actually really useful4 Port USB3 hubCons:Bad view angles (I know it's not IPS so can't expect too much)Because of this corners appear dark when viewing in the middle.Occasionally flickers when coming back from sleep

$800 for a massive and beautiful computer monitor? Why not?! That's already cheaper than Apple's 27" Thunderbolt display.Cables in the box: power cord, audio, HDMI, USB3, VGA, some sort of weird RS232 thingNotably missing: any kinds of DisplayPort cable, which you need if you want to go 60HzReally, 40"? Yup. The pixel density is roughly 109dpi, making it similar to many other computer monitors you may have owned. Side-by-side with my old Apple 27" Thunderbolt monitor, everything is about the same size, there's just more of it. This monitor is so big that there's no reason to ever mess with a dual-monitor setup again. It's everything you'll ever need, all in one place.Side-by-side with the Apple 27" Thunderbolt monitor, the Philips has a mild anti-glare coating on it, so you don't get the sharp reflections of the glossy Apple monitor. That's a big win. On the flip side, the Apple monitor is just loads brighter. You only really notice the difference when you have them side-by-side, but wow the Apple monitor is just very, very much brighter. The Apple monitor also has a bunch of things that are very appealing if you have an Apple laptop, like a Magsafe charger, built-in Ethernet, etc. All you get here is four-port USB3 hub and an analog audio jack. Paired with my MacPro desktop machine, this is no big deal.Complaints: I've got two. One that's easy to work around and the other that effectively precludes the use of this monitor with older versions of OS X.- I have a wood desk. I can see the reflection of that desk in the bottom few inches of the monitor. This reduces contrast / readability of text that's at the bottom of the screen. A non-solution would be to jack the monitor up higher with a VESA mount stand. It's already at a perfect height. I'm considering finding myself a square meter of black felt, which I'd put below the monitor, to reduce the reflections. If you're the sort of person who works in a dark cave, you'll love this. If you work in a bright white environment, you'll have complaints.- When you aren't using the computer for a while and it puts the monitor into power-saving mode, it doesn't wake up properly. You either need to yank the DisplayPort cable or power-cycle the monitor. Every. Time. There's a lot of discussion on this issue if you poke around the web. My observation was, with OS X 10.9, it didn't work. I just upgraded to OS X 10.11 ("El Capitan") and that seems to have solved the problem.Setup: After much dorking around with the settings, here's how to optimize things.- Sound through the HDMI or DisplayPort cable never seemed to work. Sound through the analog audio jack seems to work fine. I don't need high-fidelity in my office and the built-in speakers are "good enough" for videoconferencing and the odd YouTube video. I got a cheap Logitech webcam (Logitech HD Portable 1080p Webcam C615 with Autofocus), which perches nicely on top.- Turn on "pixel orbiting": this allegedly helps with screen burn-in issues (not that the manual actually says this anywhere). Also, make sure you've enabled "DisplayPort 1.2", so you can get 60Hz video.- Set your sharpness to "50" and leave brightness and contrast alone at 100 and 50, respectively. Likewise, turn off all the "smart" things. You just want this to be a big dumb monitor. The only "smart" thing you do want is "SmartUniformity". Somebody at the factory supposedly measures each and every one of these monitors and loads it with a just-for-you profile about where the screen is slightly brighter or dimmer; the "SmartUniformity" setting uses those measurements, dimming the brighter parts so it all comes out the same.- I wanted this monitor to look the same as a standard Mac monitor, which means calibrating it for a 6500K whitepoint. The native whitepoint is much higher (i.e., it's insanely blue). You can set this in the menus getting you close-but-no-cigar. I instead did a "manual" setting with R/G/B set to 100/100/100 (maximum brightness) then ran a color calibrator (XRite Colormunki Display) to get a proper D65 setting. What, you don't have a color calibrator? Here's an ICC file that you can load into your ~/Library/ColorSync/Profiles directory and then select in the "Displays" preferences. (http://www.cs.rice.edu/~dwallach/philips-bdm4065-d65.icc). Are you using a PC? Dunno, can't help you there.Summary: It's big, it's cheap, it's beautiful, it works. It could be brighter, and there are goofy issues with older versions of OS X, but for the price it's the right solution.

LOTS OF GHOSTING AND MOVEMENT BLUR, EQUIVALENT TO A VERY POOR PANEL IN THAT REGARD.But if you can get past that, colors are phenomenal and having 4K over 40" is amazing for productivity, videos, gaming (except competitively due to blur). Nice OSD and very thin panel with slim bezel. I didn't like the included stand, this arm works great MX Desk Mount LCD Arm and gives you about 3.5" off the desk which puts your eye level at about 1/2 to 1/3 from the bottom of monitor. So I'm keeping it cause there's no 4K 40" panels available without issues (And I believe that's the sweet spot for 4K) but will probably replace it in 2 years when the kinks get worked out. If there's any interest in a demonstration of the ghosting I will upload a video.

I did lot of research before building my 4K PC machine. I have been building PC since last 4-5 years (built for lot of friends and 2 for myself). I started with 22" inch monitors then went way up to 24", 27" & finally was looking for 40" (Of course no point to use a 28" monitor with 4K resolution and ant sized icons)I was NOT planning to buy this monitor. I had ordered LG 4K SMART LED TV (UF7600) 55" Screen which I felt later on was too huge. Fortunately the screen cracked during shipment and I had to refuse the shipment. Next I ordered a Samsung 48" 4K UN48JU6500 (Which has low display lag as per displaylags.com). Again the screen cracked and I was quite disappointed. Then I came to Philips monitor which was shipped from Tennessee and the screen came out cracked and I was furious on Amazon (Note : Previous 2 TVs were not from Amazon). Amazon quickly sent me a replacement via 1-day shipping and this monitor is gorgeous. I simply love it.Coming to games, I am playing with i7-5820K @ 4.2GHz, AsRock Fatality Killer, 2400MHz DDR4 RAM, SSD on Windows 8.1 Pro. I have installed. Metro Last Light, Far Cry 3, Sleeping Dogs, Tomb Raider. I am able to run all of these games at HIGHEST level of settings @4K @ 60Hz (via Display Port @ 1.2, You got to set this from monitor's setting using the joystick at back) Turn on VSYNC @ 4K else screen tearing might come for some games. Once VSYNC is ON the games will run with smoothly giving you some kind of cinema experience.I play from around 3 feet and this screen is perfect. I had to use 125% DPI just to make fonts big and I have defaulted my Chrome to 125% zoom as well. I have kept task bar as small and desktop icons as medium. On the Windows Metro app screen I have defaulted the screen to small tiles.I did not see any mouse lag which few videos and forums have described. In fact I had to turn down the mouse pointer speed from Control Panel. I use Gigabyte USB Mouse (http://www.amazon.com/Gigabyte-High-Definition-Optical-Tracking-GM-M6800/dp/B0083EZE4M/ref=sr_1_1?ie=UTF8&qid=1437376925&sr=8-1&keywords=Gigabyte+mouse&pebp=1437376938129&perid=0Z29HBG9RFTBND0KY9QE)NOTE : This Monitor does not have a display port cable. You will have to buy it separately. I am axing 1 star because the product description doesn't say anything and the box will not have it (At least US version doesn't come with Display Port cable). Also if you are planning to keep your PC Chassis on right side of monitor then get at least 3 feet version of display port cable. All display ports or on extreme left of monitor.Fun Fact : I am using Storm Trooper Case Full Tower with Corsair H100i GTX 240mm radiator. I play for 4-5 hours non-stop and my CPU temperatures do not go beyond 38 C (Idle is 27 degrees). GPU goes till 75 C degrees. I ma trying to correct some ventilation to balance out the heat. But overall I am quite satisfied with the build and gaming experience.----------I forgot to mention these monitors have speakers as well. Sound quality is pretty good. I have used Dell, Samsung and ASUS monitors in past and the sound is for name sake in them.

The first one I got have the following problems:1. It sometimes reset itself (i.e. turn into power saving mode and then turn on immediately) in 4k 60hz mode. This happens to me almost every day which is quite annoying.2. It occasionally loss all the settings and I have to readjust the brightness etc. This happens once a week and I can live with it.3. The holes on the base to put the screws is not aligned perfectly and the monitor shakes a little if I move it after installed. It doesn't really bother me at all.I had to exchange the first one I get and there are still some issues with the replacement which I decided to keep. 2 and 3 don't happen any more but I still sometimes get 1, though much less.Overall, even with the first one, I still think it is definitely worth the money as I suddenly have a much larger screen asset to use. Amazon's customer service is great as usual and I am quite satisfied with the second one so far!

the cable works really well, i am using it to push a 4k monitor in 60hz from my laptop's mini dp port. The only downside i would give it is the plastic shell around the connectors are really cheap, they are hollow plastic, imagine the cheapest piece of shaky plastic you have seen, clipped together, that's what it's like. The clip on the display port is also made out of the same plastic, it doesn't feel like it will break with regular use, but if you are gonna be plugging it in and out regularly like i am, i see where it will definitely break or wear down over time. Can't really complain for the price though.

The cable works. I am using this cable to connect my BenQ XL2720z monitor to my computer so that I can display at 144hz.The cable is good quality and fits in the ports nicely. The price is good and six feet is more than I needed. I was worried that this version of the cable would not push over 120hz but after some research I found that the version 1.1a cable meets the 1.2 requirements and is able to push over 120hz. So far I haven't had any problems with pushing 144hz. If I ever need another DP cable this is where I'd go.One thing to note though is that I think you will need a 1.2 version DP port to push over 120hz. I don't think version 1.1 or earlier ports have the bandwidth to do 120hz but I'm not a hundred percent on that. This cable will work fine regardless of what version port you have. Its just that if you don't have a version 1.2 port you may not be able to increase your refresh rate up to 120hz or higher but you could still display at 60hz.

I recently got a WQHD monitor, and this cable is required for driving the monitor at its native resolution from my macbook. The HDMI cable only can do 1080p.The bulge on the mini end makes it a little easier to handle, but I think it is a design flaw, because sometimes those ports are pretty close together and it can obstruct a device on an adjacent port. That's why i gave 4 instead of 5 stars.

My original review was one star, because the cable stopped working after 40 days of use (and 8 days after the return window), having only unplugged/plugged it in about 4-5 times. Kudos to Cable Matters for standing behind their product though, as they contacted me immediately based on my negative review here, and sent a replacement cable.It appears to be working fine, though I've only been using it now for about 10 days. I will update this review again if it fails like the last one did.Because Cable Matters promptly sent out a no-cost replacement, I'm changing my original 1 star review to 4 stars (deducting one for the hassle of a defective product).

Started our fine, but signal failed after about 6 weeks and maybe a couple of dozen uses.I had this connected to an external monitor, and would connect my work laptop or home macbook when I needed a dual monitor setup. At first, I thought the connector wasn't fully engaged in the Mini DP port on the laptop/Mac, but then it just quit linking to the monitor. I tried it on another monitor...same issue. I ended up buying another cable from another brand. Won't be buying from these guys again.Update-April 4th,2014After posting my original review, Cable Matters contacted me via e-mail with a very nice letter of apology and offered to replace the cable at no charge, provided I a) returned the defective cable to them in the pre-paid envelope they sent, and; b) consider updating my review here on Amazon.I think that was a fair request and I appreciate them reaching out to make things right. The replacement cable arrived within a few days, and seems to be working fine. Accordingly, Im updating my review from the original 1 star to 4 stars.Hopefully, this cable will fare better than the original, but regardless, I am impressed by a supplier that tries to address customer issues, and I have to say Cable Matters did just that. My thanks to them for their efforts.

At first I thought either this cable or my new 24" HP LED monitor was defective, as the monitor would loose it's signal from the computer this cable was connected with, when switching input from a 2nd computer (a HP tower on one side, using a DVI to HDMI cable, and MacBook on the other side using this cable). Turns out there is a setting in the LED monitor itself that needed to be changed. Before I figured that out, I ordered another cable from a different company that, upon arrival, was identical to Cable Matters cable, and obviously from the same factory. I'm going to keep both cables since some reviewers mention the cable failing after a few months.

I received this Monitor today in the mail, just turned it on and start using it and after a couple of hours that strange bar appeared while I was editing video, it's hard to notice it watching videos and stuff, but once you see it, it's there all the time, you can't unsee that thing.Size and image quality are STUNNING, but that's a real issue.

I finally gave up and return it. The KBM lag is so bad that it is not functional at all. I have a VAIO Z Canvas with a display port emitting 3840 @ 60 Hz. I am not in gaming and the setup has no such problem with a Dell 30" 2560x1600. Hope there is improvements down the road to address this problem. The mentioning of the burn-in problem in the manual is troubling. There is a lot of times I left monitor on for > 20 minutes. I left my side and bottom menu bars there for years and no burn-in problem.

I love everything about it except I don't seem to be able to get the one screen set up in the high resolution mode.

Pros-1. Great blacks almost OLED level2. Colours looks great3. 4k at 40" is perfectCons-1. When viewing colours on a grey background I notice the colours are displayed in bars through out the screen2. Dark in corners but not distracting in anyway.3. Screen sometimes flickers green and goes crazy when pc is turning on (May just be my 970 and pc setup)AND THE BIGGEST PROBLEM !!My first monitor came with a cluster of dead pixels on the right side of the monitor and now my second monitor has a cluster of Stuck pixels on the left side of the monitor.Conclusion-It really is a great monitor and I don't know if I'm unlucky or what buy this is the only monitor out of the many I have owned that have had dead and stuck pixels. Philips you really need to step up you quality control, the fact that I have had two defective monitors in a row is very frustrating.Note- Monitors were purchased from Bestbuy.

I'm a programmer, and having all the space is nice, but the colors in this monitor are a joke. Every single time I see it next to another screen, part of me regrets this purchase.

It's nice, but it blanks out for a couple seconds then comes back 3-4 times a day (4K @ 60Hz on a GTX 980 Ti). It's annoying, but not nearly annoying as having my work spread across multiple monitors, so I'll probably keep it.

Cable works fine as advertised, but I had purchased 2 to hook up into a Mac mini. You'll notice that there is a significant amount of unnecessary shielding around the Minidisplayport connector. There's so much extra shielding, that you cannot use two side by side.

Bought these to connect to a Mac Mini and I'd hoped to use two of them to support my dual monitors. Unfortunately the connectors that plug into the Mac Mini won't fit next to one another, because the Thunderbolt connector housing is too bulky. So I used only one of them and used the HDMI port for the other monitor.

Lasted a year and a month. One month longer than the 1 year Limited Warranty. In my configuration and use, it gets plugged and unplugged once a day as I bring my laptop home from work and back each day. It started showing signs of intermittent connection for a week: I could jiggle it to make it work. Then I couldn't make it work.I just bought another. Too much bother to find another brand.

It's OK for 6 month only, after that, the cable start fail every other time, and then it gets unusable. but for the first 6 month it's a very good cable. This happen me twice (I bought one on March 2015, and other on April 2014).Now I think I ain't gonna buy it again.

It works just fine. There is just one issue I might have problems with later, and any Apple owners should make note of: On this cable's Mini DisplayPort connector, there is a weird "bulge" in the plastic that surrounds the MDP. On many Apple products with 2 Mini DisplayPort inputs (MBP and MacMini), the inputs are too close to allow you to use 2 of these cables side by side. While this might be a fringe case for some, it's a huge issue for me as my two main computers are both Apple products and both affected buy these bulges. Otherwise they seem to be fine.

Construction of the cable seems pretty good, however when I used this with my 144hz 1440p monitor I could only manage to get 60hz out of it.My graphics card is a Radeon 7950 which has mini-displayport out and the monitor only accepts displayport in. I read up on the specs of both mini-DP and DP and both are apparently good enough for that amount of data transfer so I'm not sure why I was limited to 60hz. I'll be getting a new card soon anyway and won't need this cable after it arrives but it's worth noting that it doesn't perform as well as a full DP cable.

The quality of the screen is to far ahead of the software and hardware needed to run this. The screen itself, when it worked, was really quite beautiful. After countless hours of pixel peaking, it truly was a lot clearer and sharper without distortion than any other 1080 or 2650 screen i had in possession. But the Achilles heal was i could almost never get it to properly set at 60hz and somehow the internal software kept resetting itself the output at 30hz.For all the extra pixels, this type of performance killing problems is not worth it over a good 120hz 2560 screen with super clear FPS and smooth transitions colors. At 30hz this screen absolutely sucks. Even when watching bluray movies you can see it was just noticeably slower than on other screens running at 60hz or 120hz. I ultimately traded this in for the BenQ xl2730z. Which is significantly better for what i was looking for.

GOOD:I agree with the other reviews that the extra screen space is fantastic. I can view quite a bit of material at one time, allowing me to have all the key elements of my development environment visible at once, with minimal alt-tabing. It serves as both a monitor and a tv for me, as it is in my living room in my tiny apartment. For this, it does a really good job.BAD:If you've not yet purchased this monitor, search "BDM4065UC color banding" on youtube. You will see severe color banding problems that, once noticed, cannot be unseen. I'd read about others with this problem, but people are never very specific about their video card, drivers, which connection they were using or any other technical details that could have ruled out user error. After owning this monitor, It does not appear to be user error. I found the color banding to remain on DP, miniDP and HDMI connections driven by either a GTX 750 Ti, or a GTX 970. I ensured all drivers were completely up to date, and repeatedly tried the windows color calibration process to see if i could get any better results. I only tested on windows 7 and 10. I have read a few things suggesting the problem does not exist for linux users, which, if true, would still point to a driver issue that phillips should feel obligated to address.If you are looking for an extra large 4k display, especially if you do any image heavy work for artistic or analysis purposes, wait until a different model comes out, and it may be a good idea to avoid Phillips entirely. This monitor is not worth the ~$750 I paid for it, and I am disappointed that I only fully realized the magnitude of the problem a week after my return policy expired.

I came from a triple-head setup with a retina MacBook Pro 15" at the bottom, a 27" WQHD (2560x1440) display above, and a 24" WUXGA (1920x1200) display to the left. As a work-at-home dev-ops guy that does pretty much everything IT-related for my company, I'm tasked with way too much to keep track of, so having screen real estate was a must.When I saw this monitor, I was very intrigued.WUXGA @24" = 94 PPIWQHD @27" = 109 PPIUHD @40" = 110 PPISo it's all relatively close as far as PPI goes, right? So take the pixel density of my 27" and the resolution size of my 24"... and nearly QUADRUPLE it. What could go wrong? Well, quite a bit, apparently.1) Sub-pixel Rendering Gone WrongThe panel used in this Philips is a semi-rarer type that uses pixels that have their sub-pixel colors BACKWARDS, so it goes Blue->Green->Red, instead of the standard Red->Green->Blue. There are many sites that explain this problem, and you can Wikipedia "Subpixel rendering" to get a good overview of how it works, and what it affects. The end result is, when your OS tries to use anti-aliasing while expecting an RGB panel, you get very ugly text with rainbow-looking edges. My eyes were so sore after working with this monitor (from this, and the other problems combined) that I was sure I was going to have to send this thing back.However, not everything is lost. In Windows, you can use the ClearType Text Tuner to change your sub-pixel rendering options to an extent, and that greatly helps. Also, by scaling things the system to 125% or 150%, the edge-pixel-to-font-size ratio is significantly lower, yielding in less distortion even without changing ClearType. In OS X, you have to use command-line voodoo to alter a UI setting that Apple recently removed from the System Preferences, and just setting the antialiasing to work using grayscale (not optimum, but in Yosemite, that's as good as you can get).2) ClarityDespite having a similar PPI to my WQHD display, the clarity is anything but. There is significant color/light bleed between pixels (you can see "auras" around bright colors-on-white), and often times, dark backgrounds can create horizontal lines that go quite the distance across the screen. Reminds me of really cheap, budget panels used in those sub-$100 tablets, although not that severe. Just bad enough to make my eyes sore to work at native 100% resolution.At 150%, it's not noticeable anymore, but that simply takes a UHD display down to the effective resolution of WQHD, while giving me somewhat enhanced pixel density, minus some clarity. It's almost a zero-sum game here compared to the WQHD for productivity goes -- except that it leaves no room for my 24" on my desk, so I'm having to go without my 3rd monitor. I'm really having to ask myself if the compromise was worth the price I paid for it.3) Viewing angles, color/backlight uniformityCorners are 20-40% darker than the rest of the screen. What the heck. Can hardly read my clock in Windows sometimes. I have to move my head around to get optimum color.Colors are too blue and bright, and my mid-30's eyes can't take more than 15 minutes of it. Reducing brightness and customizing color to reduce the blue channel a bit have greatly helped with matching my MacBook's white levels.There are horizontal bands of dark regions that are noticeable on white backgrounds. Kinda expected this, given the panel type and the price bracket, so I can't really fault it, but it's something all prospective buyers should definitely be aware of. When scrolling black text on white background, there is definite ghosting of text that is often noticeable. Annoying, but doesn't really detract from anything... yet...4) DefectsMine has 14+ dead/gray pixels. At this pixel density, I figured that's only to be expected... and at 150% + distance, I can't really see them most of the time. But I'd have liked one that was flawless since it IS rather expensive still.When I wake up my MacBook on Mini-DP, or my desktop gaming computer on DP, it will often briefly start up, show garbled pixels for < 0.5sec, shut off, and repeat the process for 2-6 times before coming back on with a stable image. It happens consistently every time. I wonder if that's a defect, but so far, power-cycling it prevents it from happening, and I'm not sure I've seen it happen on my Xbox One on HDMI either, so that's something I'd have to experiment with to see what causes it.Overall, my expectations were shattered. In a bad way. My poor eyes just couldn't take it anymore and I was ready to box it up, but running it at 150% scaling, changing my antialias settings, and changing my brightness/color settings improved my experience enough that I've been able to tolerate it for the past 2 months. In retrospect, it would have probably been better to still return it and wait for a better panel to come out, because I'm not able to use it the way I intended it... but I let the return period go by without making a decision, so now I'm stuck with it.On the bright side, having a 40" UHD screen to play your favorite PC games is an absolute blast. The difference is amazing, whether it's FPS or MMO. I don't notice any ghosting when it's a game, and pixel clarity doesn't matter too much when you're looking at the whole 40". Sadly, a lot of modern games (especially MMOs) have to be set to Low to play smoothly at UHD on my GTX 970. But I kinda knew that, and I could always lower the resolution if I wanted quality... But playing on Low at UHD subjectively looks nicer to me, so I'm still content with it for now.Hopefully this helps people on the fence about this monitor.

Short version:4k makes these larger screen sizes great for productivity. My unit had build quality issues, so the time spent with it was unfortunately short. I'm returning it, and will probably hold out until the bigger names provide a higher quality alternative with the features I need. Once the 4k/40" euphoria wears off, you're left with a mediocre display, I think.Longer version:I'm a web designer and developer, so I do a bit of everything... code, Photoshop, spreadsheets, etc. I bought this to try it out as a replacement for dual 27" Apple Monitors at my office. I've been happy with the monitors I have, but wanted to try a larger, single display for more screen space. My laptop has Displayport 1.2, but no HDMI 2, so requiring Displayport reduces your choices in the > 34" space pretty quick.4k at a screen this size is very helpful when you want to view graphic work at full scale or larger without losing perspective. It's also pretty nice for writing code. You can allocate a lot of space for the code view, without sacrificing property and navigation panels or moving them to other screens and straining your neck. It does seem to provide a more cohesive experience on projects. Complex, large spreadsheets are amazing at this size! My boss wanted to get one this size for himself after I showed him some stuff in Excel.At a distance of 2-3 feet, I think I'd be a lot happier with a curved screen. This particular monitor has brightness and color fade when you look to the edges and corners. Not unexpected for a non-IPS display of this size from that distance. However, if that space is going to be truly usable, I don't want to have to shift my head to either side to counteract dimming or washout.The build quality (or quality assurance) was lacking for mine. the metal bracket that mounts the stand to the screen was slightly twisted, causing the screen to twist as well. The top right side of the monitor angled back about a 1/2" inch, when compared to the other side. Also, the stand would not sit flat when mounted to the screen. Lastly, the same metal bracket that was twisted was also angled back to the point it was annoying (there are no adjustments at all). Hopefully these are just small quality issues with a particular batch.So, yeah, I think I'm sold on the idea of a monitor this size and resolution, but just not this one. Once the shock/excitement of the jump in screen size wears off, you're left with a mediocre display, I think. If you don't need Displayport 1.2, you may have more options. If you do need a DP 1.2 capable monitor, I would wait until better options start showing up in this size.

ProsA lot of real estate as you all know, nice color, not heavyCons1. dead pixels shows up in a few days of use,2. the stand is flimsy (nothing compared to my Benq BL3200 that I planned to replace), no swivel, no height, no tilt adjustment,3. glare screen makes reading extremely hard4. makes one of my Gigabyte Brix mini PC (with win 81) lost video all the time, don't know the reason maybe a video sync issue

Found out the hard way this cable doesn't work with an early 2013 Macbook Pro w/retina display because the Thunderbolt ports are first generation. Cable works fine on another laptop. Really needed this to work with a 4k monitor and my MacBook. Found a way to make it work with an HDMI cable.

It does its job. have had no issues. Will update if any arise!Update 3/18/17: Bought the cable last September, it just died on me. I went to start my PC one day and only one of my monitors connected. I switched cables and my monitor still works, so it has to be the cable. Worked great for 6 months!

Worked great right out of the box...only solution to get full resolution out of my Dell monitor. Until I tried to remove the cable from the back. The little latches are hard to press down, so I pulled a little hard and the cable head literally disintegrated in my hand. VERY poorly constructed, almost like it was not made in a factory.So, it works, but might fall apart if you wiggle it too much. Buying it again to replace the old one, no other options.

This cable was great while it worked, but recently failed, most likely from bending it too much.I purchased this cable to connect my MacBook to a 24" monitor, it worked well, did its job until it started to fail/blink, then give a noisy signal.I'm guessing it started to fail because I unplug and replug my laptop into my monitor often. It is a thick cable and I guess that did not help the situation. Anyways, I've had it for less than a month and it has stopped working all together.

It seems this product is really hit or miss. I purchased it happily and used it with exuberance on my shiney new VG248QE, a 144hz monitor from ASUS.Unfortunately, after about a week of happy gaming I woke one day to "Displayport NO SIGNAL". My CCC pops up and tells me that I have a problem with the link/displayport. I swap to HDMI (which makes me lose out on the 144hz benefits for the monitor) and the monitor springs up to life.I read reviews, and find that other people have had problems with this cable dying in a short period of time -- though none as short as a week, like mine has.I will purchase a different cable and report back whether or not it was truly the cable -- but in the meantime, be cautious going forward!

Unable to support over 800x600 resolution after two months. ATI Catalyst says DP cable has malfunctioned. I bought two cables, the other works, also tested it in my other DP port to verify no issues with port. Going to have to buy a different brand now. I will admit that I regularly unplug and replug in this cable in order to force my graphics card to output sound through HDMI rather than the DP ports as they take priority. I would estimate I've unplugged it around twenty times at this point.

Had no clue that this display was a poorly supported monitor for Apple Macintosh. No drivers at all. I got it to work on my fully loaded Apple iMac 5K machine, but it flickers to get going and often fails to connect, which follows by a reboot. When it does work, I have zero adjustments because there are no drivers for the Mac.Aside from that. The corners vignette really bad and the resolution is subpar. Keep in mind, I'm comparing to Apple's 5K 27" display that is native to the iMac.

*UPDATE* Well after a month and a half of use, the monitor is showing some defects. Monitor is flickering and takes a while to activate when computer resumes from sleep. Very sad and frustrated. Hopefully it's covered under warranty...Monitor works great and a plethora of cables are included, accept for a mini display port cable, which is confusing since the monitor on the back has a mini display port hookup. I uses this with a Windows 10 laptop so I had to have one. Luckily I had a spare in my closet. Otherwise no complaints, this is a superb monitor.To enable 4K at 60hz over Display Port, reach around the back right of the monitor to the little square button. Tap it to the right, then tap down 7 times. Set Display Port to 1.2. Reboot your computer and it should work.The only reason it is not 5 stars is because of a small cluster of dead pixels near the bottom left of the monitor.

s***ty quality control.Got huge bright line at top of the screen (covering like 50% of width and around 10-19px height) - it made it impossible to work especially when screen is black. Also non-tintable display puts your head in very uncomfortable position. I followed review of a person saying it's great for development purposes, but it didn't work for me and I replaced it with ASUS PA328Q, which is more expensive but you get what you pay for.

When I have a GUI window open on the screen I see streaks of color discoloration around it. The streaks move with the window if I drag it around the screen. This doesn't prevent me from using it, but I feel disappointed in this purchase every time I see the discoloration.

bezel top center was bent up. bent bezel allowed back light/ edgelight to shine directly at the user. Returned item.

I was really looking forward to receiving this monitor. Unfortunately it arrived DOA. I tried everything including turning the switch on and off, pressing and moving the joystick in all directions, changing power chords and electrical outlet, turning the computer on, etc. Nothing worked. The LED light in the front never came on and the monitor itself did not turn on. Also the display port cable was missing from the box.

Must be made as cheaply as possible. Literally stopped working after 8 hours of use. Buy a different one.

I have had 2 of 4 cables fail on me. One lasted about a month, the other lasted around 2.5 months (randomly failed today). I have also had 1 of 2 Cables Matters brand HDMI 90 degree adapters fail on me as well (it was DOA). A 50% failure rate is absolutely unacceptable and I am now done with everything made and sold by Cable Matters. I highly recommend looking elsewhere for electronics connections and cables.

Cable failed after 6 weeks of use. My experience is exactly like California Bill's when he writes:"Started out fine, but signal failed after about 6 weeks ... I had this connected to an external monitor, and would connect my work laptop or home macbook when I needed a dual monitor setup. At first, I thought the connector wasn't fully engaged in the Mini DP port on the laptop/Mac, but then it just quit linking to the monitor. I tried it on another monitor...same issue. I ended up buying another cable from another brand. Won't be buying from these guys again."The difference is that I had this connected to a Mac Mini and brand new monitor for the past 6 weeks and it got about 2-3 hours of use per day. Like Bill's, mine flickered in a way that made me question if the connector wasn't fully engaged and then it just stopped sending a signal earlier today.Very disappointing since the 30-day return policy expired 10 days ago. And, although Cable Matters offers a "one-year limited warranty" on this cable, when you go to their seller information page and look up the warranty information, it just refers you back to Amazon (who won't replace the cable because it's been more than 30 days since purchased). Those are your options. Super frustrating.My only advice is to look elsewhere for a similar item.

This cable stopped working after a few months of use. My monitor started having issues with flickering and going black. I thought my GPU was going out on me but I swapped back to HDMI and the issues went away. Disappointed I haven't been able to use my monitor to full potential since and don't want to waste money on another cable that will go out again.

I purchased this cable to pair with a MacBook Pro and a Dell 23" display here in our office. Unfortunately, it developed an annoying flicker problem after a couple of months. The Dell monitor works just fine on another PC, so I'm going to buy another cable from a different seller. This one did not cut it.

Bought two of these cables for two separate monitors and they worked well at first, maybe had to jiggle it a bit to get it to connect, but after two months one started to fritz out. Thought maybe just a dud or the monitor, but then the other cable started fritzing out on that monitor, swapped around and bought a new cable and it was in fact the cables. Both wore out at around the same time and only had them for 2 months.
