I do recommend this monitor if you are looking for a 4K one. I think the higher price is worth it to get the IPS panel vs the cheaper TFT 4K panels. Though not perfect, I gave this monitor five stars because it looks to be the best 4K IPS monitor available (for the price).
///GOOD THINGS///
-> THIN BEZELS – 0.5”
-> MATTE BLACK PLASTIC - looks nice and doesn’t attract fingerprints
-> GREAT STAND - can be raised/lowered, tilted forward/backward, swiveled, or even rotated vertically
-> MATTE SCREEN FINISH - not as “vivid” as glossier screens but no glare is the better trade-off)
-> IPS SCREEN – Helps the colors to look more uniform – makes a big difference on a monitor this big.
-> FLICKER-FREE SCREEN – Asus advertises this monitor as ‘flicker-free’ – and I do get very little eyestrain using this monitor compared to others.
-> 4K RESOLUTION – It’s great. As others have said, you need to enable DisplayPort 1.2 in the menu to get 4K at 60 Hz. I also got a much better picture after setting the ‘output dynamic range’ option in the nVidia control panel to full (it was at limited initially). Regarding desktop scaling in Windows – 4K at 150% scaling is about like 1440p at 100% scaling. Trying to use this monitor at 100% scaling is pretty difficult – everything’s really tiny but it’s nice to be able to fit so much on the screen at once. I find that I like to use 125% scaling the best. The 4K does make a big difference in games compared to 1440p – I especially like the higher resolution for strategy games.
///BAD THINGS///
-> SCREEN IMPERFECTIONS – a couple pixels are stuck red and a couple are dead – most of these have occurred months after buying which is worrisome – the good news is the pixels are so small it’s hard to notice.
///NEUTRAL THINGS///
-> BUILT-IN SPEAKERS – Can’t hurt to have them but pretty mediocre sounding. Volume can be adjusted in the monitor’s menu. Built-in speakers can be disabled in the menu as well.
-> NO DVI PORTS – Doesn’t affect me but something to be aware of.
-> IPS GLOW – The edges of the screen do look slightly brighter on a dark image – but the effect is no worse than it is on my MacBook’s “retina” screen. I’ve found the IPS glow effect looks worse in pictures than it does in person.
-> LOW BLUE LIGHT SETTING – Feature that makes the screen more yellowish to reduce eyestrain – it does help but isn’t something I use much. It can be set at five different levels (including off).
-> VIVID PIXEL SETTING – I prefer this set to the default of zero. Turning it on makes text look artificially sharp like turning up the sharpness too high on a TV.
-> TRACE FREE SETTING -> Does make a difference when it’s on – if it’s off I notice the cursor blur more. I like the default setting of 40 best.
///INPUTS///
-> 4 HDMI – These are not HDMI 2.0 ports. You can use all four of them at the same time in PBP mode.
-> 3.5mm audio in – can be assigned to any input
-> 3.5mm audio out – good for connecting computer speakers to or headphones. Note that the quality is limited to 16 bit, 48 kHz.
-> 1 DisplayPort (DP) and 1 mini-DisplayPort (mDP)
UPDATE 2016-9-12
I just wanted to say that after six months, this monitor began to have a problem with flickering so I RMA'd it through ASUS. When I got the monitor back from them, there were dozens of stuck pixels and the screen flickered multiple times every second or so. So I sent it back to ASUS for a second time, and they sent me a new monitor that had clusters of dead pixels on the screen, so I sent it back to ASUS a third time, and after two weeks they send me an email saying they have a part shortage and no estimate for the repair. They offered to send me the cheaper TFT version of this monitor instead - I find myself doubting that they lack the capability to send me a replacement monitor matching the model I actually bought in the first place. ASUS has very friendly and nice support when I'm on the phone (even though the wait was close to an hour when calling) or live chatting, but their service department seems to not have the slightest care whether the monitor they are sending back to you actually works.

Other than that it is a good monitor.
