A nice and big 4K screen with good colors and contrast, but an eye hazard for some.
So this is going to be a long review, because I have to go in-depth to explain some issues.
I started using this monitor in mid June 2015.
Now, first off; my jaw dropped when first trying a 40 inch 4K screen as a PC monitor for stuff like gaming or viewing high resolution photos. Absolutely amazing. Even with gaming in mind, it's pretty decent as there isn't too much input lag, albeit slightly noticable when compared to faster gaming monitors.
But the fun ends there. I guess I was too blinded by it's awesome resolution, size, and colors/contrast to fully acknowledge it's flaws early on.
One of the main things that bother me is that the backlight uses Pulse Width Modulation (PWM) to dim the brightness. Quickly explained for anyone who doesn't know that this is: it basically means that when any brightness setting below 100% is used, the backlight will flicker; and will do so at lower frequencies the lower the brightness is set. How is this a problem? Because even though the frequency is still so high you can't actually perceive any flickering/strobing by yourself, your eyes and brain surely can. For some people (including me) this causes severe eye strain and headaches over time. So the issue is, I either have to put up with low brightness with a side of eye strain and headaches, or maximum brightness and.... well, kind of the same thing, because then it is just way too bright. And just to dispel any doubts here: I almost NEVER get headaches, very rarely. I can use a flicker-free monitor/TV for a whole day, no problem. But with this one, the headaches usually set in within 3-5 hours, and by then it's painful for the rest of the day. There's no coincidences in play here, I'm 100% sure it's caused by the PWM backlight control. During a moment of eye strain and headache, something as simple as looking away or looking at a different monitor instantly makes this "stinging" sensation in my eyes go away.
I should also mention, the panel is very glossy and reflective. This brings a huge dilemma; either use the monitor in bright conditions to suffer less from eye strain, but spend a lot of time looking at your reflection. At least you'll easily spot the serial killer who broke into your house and is sneaking up on you. Either that or use it in a dark room and struggle with the brightness of the backlight.
Yet another problem is the panel and backlight seem to be a lottery game. My monitor has some noticeable backlight bleed/clouding issue in the shape of a bar that goes horizontally all the way across the panel. Also other parts of the panel seem to have slight clouding and uniformity issues. Very noticably is that the corners of the screen are much darker than they should, it almost looks like a vignette effect.
The last gripe I have with this monitor (though not as severe) is that there is NO adjustment options whatsoever. I wouldn't mind much if there was no swivel or pivot, but not having the option for tilting and height adjustment is a no go. Now, this is somewhat fixable. It's possible to get a custom stand and attach it to the VESA mount, but that's enother expense outside of the already high price of this monitor.
I do realize this comes off nitpicking on little problems, but the reality is that despite it's awesome size, resolution and color quality, it is not a monitor that is comfortable to use. Whether it's for office work, video/photo editing, web browsing, gaming, movie watching, it's flaws would plague any user.

Excellent monitor, only one of its kind in the U.S. right now
I'm a professional film composer and I've been researching 4k monitors for a year now due to the productivity boost that all those pixels allow for. Surprisingly, this Philips monitor is still the only available large-format 4k computer monitor available in the U.S., so I finally picked one up (UHD TVs don't work as proper computer monitors).
In short, it is stunning to have this much 'real estate' available, and quite a productivity boost. As a Mac user, my standards are high, and I'm happy to report that once calibrated, the colors look great and the contrast is insanely good.
The only downsides are:
1. slight uniformity issues (brightness drops off a bit in corners) - but as picky as I am, it's not a deal breaker given the massive trade-up in workspace.
2. when first powered on or woken from sleep, the display will randomly flicker off and on a few times - sometimes several minutes later. That's really startling and disconcerting. It eventually settles down, but it doesn't inspire confidence.
3. it uses a nonstandard BGR sub pixel layout instead of RGB, so Mac users will have to put up with ever-so-slightly dull text rendering at full resolution. Not a huge deal, but it's noticeable if you're used to a 'retina' display.
Overall, this display is quite an advance, and the only one of its kind right now. Other than the flickering issue, I'm thrilled with it!

Superb Ultra HD 4K PC Monitor
Fantastic Ultra HD 4K PC Monitor. Highly detailed vibrant sharp picture. Scaling is excellent. Contrast & brightness are terrific.
The only minor downside is slight barely noticeable inversion artifacts when dragging a window on the desktop but this is not visible in gaming or watching a Bluray movie.

Beautiful display properties
I had a problem in that my initial delivery from Amazon died on me within 3 weeks, however, Amazon immediately authorized a replacement, and I have now received the replacement. For the price this an excellent full-house display with incredible clarity-very happy with it and considering a second purchase-of hopefully an updated version in the very near future. What about a 55 inch monitor?

The OSD setup facility lets this excellent monitor down
I would have given this otherwise excellent monitor 5 stars if the OSD facility for setting it up wasn't so clumsy and badly designed, it being manipulated by a fairly 'iffy' joystick in a get-attable but awkward position at the rear bottom right hand corner . In fairness to Phillips they have attempted to get round this with a "Smart Control" software application, but unfortunately this is also fairly useless as a lot of the functions in the OSD setup menu don't exist or don't work #on Windows 10#
One improvement that is badly needed is for the Smart Control software to provide the facility to switch the "Picture in Picture" function on or off. Trying to do this via the joystick is a frustrating experience which I gave up on, especially since the volume adjustment and mute function are done in the same way.
The screen is huge and the display is excellent, and setting it up on my Windows System on Windows 10 was a breeze. By using the windows display scaling features it can be set up to suit all tastes. I have it set at 150% which I find just right for desktop use. There are preset setups available in the OSD menus, but it might be easier to use the NVidia control panel to achieve similar results, I haven't looked at this yet.
Lots of input sources, my preference was to ignore the audio side, and set the OSD user key #joystick down# to choose the input source.
Despite the OSD shortcomings, I would still recommend this beast of a monitor because it looks so good! Let's hope that Phillips or whoever they employ to write the control software give us a comprehensive set up tool that can be used from Windows in the future.

Lovely looking screen. This is perfect for the heavy PC user looking a lot of screen real estate. I move from a similarly sized TV as a screen to this and have been largely blown away. Gaming is a dream even if you can't use 4k. Just changing to 1440p or 1080p and the screen still looks great. If your PC isn't super powerful this screen should at the very least future proof you until your PC is. I mean even 1360 by 768 looked ok (go to a minimum of 1080 or 1440) though. The displayport cable was a good 2m long and fully supports 4k 60Hz (change to displayport 1.2 in the screen settings menu though). Don't cheap out and use a subpar cable though like I did, just use the good one Phillips provide in the box...

Great Overall but for OSM
Great display in general but the on-screen menu system is clunky.
As for the other poster indicating it does not work with display port he is incorrect, both my machines run 970's and Display port is fine at 4K 60hz. but you need to set it in the setup menu to accept Display port 1.2 as from the factory it is set to 1.1(don't know the reason).
Some people should read instruction manuals before incorrectly posting issues which are clearly not there.

I wanted a large screen 4k display for a dedicated flightsim PC. Most "large" monitors seemed to max out at about 28 inches, so I had decided to buy a 40 inch 4k TV instead. And then I found this monitor via a review. Was always going to feel more comfortable with a PC Monitor than a TV, and have had good experiences with Philips products before so bought one.
It is excellent. Got it running as a single screen, full 4k at 60hz via DisplayPort (after amending the DP level via the OSD setup menu) - motion is smooth (from NVIDIA GTX 980 TI) and image sharp and clear. Haven't played with all the picture-in-picture options and not likely to but they seem quite handy. Sharing this monitor between 2 PCs would make sense.
Oh, and the sound quality from the built in speakers is good as well.
Highly recommended. Makes my other systems feel very inadequate now. And if I get anything like the 20+ years I got from my large screen Philips CRT TV I will be a very happy bunny.
