Really, really nice for TN

Bought this about a week ago - here in Aus (not from Overclockers - would if I could!). For a PC hardware enthusiast and enthusiastic (but not pro) gamer like myself, this is a really sweet screen. Obviously using display port to give 60hz is a must, and (for me) 60hz is absolutely fine. I do have a solid rig (i7 3770k, 2X R9290's, 16GB RAM etc) and to run games at full res this is a must; with new games anti-aliasing turned off but not required anyway.

Using on desktop, with Windows scaling, is still SO much nicer than 1080p. Don't listen to naysayers, Windows scaling on the whole has been good and the picture is gorgeous - the scaling doesn't dampen the experience at all, it's so sharp. Going back to 1080 now feels like going from HD to DVD did.

I am no pro with graphics, photography etc so I can't talk for that, but as I said above, for someone like me who loves games and hardware, the colour and resolution for TN on this display - at this price - is great. Fully adjustable stand means viewing angle issues are hardly a concern.

I can also testify that I have no issues at all with flickering, dead pixels, anything. Obviously, I really recommend this monitor, only downsides I can contribute are the plasticky feel and design and the OSD is pretty poor. The panel quality and adjustability compensates for the design, but I do wish there were some more options in the OSD; PIP is very clunky and slow for example, not that I use it.



Good monitor

Not sold as a gaming monitor but very capable, minimal issues with ghosting etc when playing at 60hz.
Key issues (as seen below in other reviews) probably relate to the fairly early adoption of 4k tech before it has time to bed in, and whilst older technology with no support for 4k res, but with display ports (e.g hd6xxx series) are being used.
I am using display port at 60hz on a 290x with current drivers. There are no issues with flickering (although when i used the same setup on linux, there was this issue and this was solved by turning the monitor on and off - presumably redetection solved the flickering). I didn't realise there was a driver for it, but have downloaded from the Acer site and it installs with no trouble (unlike the previous reviewer), if you add it as a custom driver (from list) in windows 7.
In summary a cheap 4k monitor, capable of gaming reasonably well, and a with few (resolvable) issues.


nice but has a serious issue

first off this is a nice monitor with a very clean design and sturdy stand.

however i am having a serious issue with ghosting on it... in Dota 2 for example when panning the camera it feels like the contrast of the monitor has been boosted nearly 100% and when moving the cursor across the screen there is a serious dark ghosted trail left by the cursor and any windows or objects in game etc...

really has frustrated me quite a lot seeing as this isnt a cheap monitor and my 1080p tn acer panel (same panel tech) doesnt have this problem...


Great value for money

Well i went from a cheap 1080P HP TN panel, i was debating going with a 1440P ips, 1440P 120/144Hz or tn 4k 60hz. I'm glad i choose 4k because it means i should last me longer without needing replacing and also i can fit loads on the screen. Everything seem small and very sharp at first, but once you've got used to it, going back to 1080p is like going from 1080p to 720p. Also you really need 2 cards to actually game at 4k. even with my 970's i have to play some games at 1440P to maintain utlra textures and a decent fps.
- I think the colours are great and the viewing angle isn't too bad.
- The stand is solid and has loads of adjustment which is very important to get the viewing angle correct.
- It has a good range of inputs, but bare in mind display port is the only one that supports 4K@60Hz, unlike some monitor which support 4K@30Hz through HDMI as well.


Works great if you know what you are doi

No dead pixels. Be warned if you only using this monitor via display port at 3840x2160 @60hz you see flicking when at desktop. To fix that I was going to use my old 27" AOC monitor to setup a dual display and it fixed the flicking at desktop so now it works perfect , looks great and I play bf4 on amd 280 g-card at low setting and getting around 60 fps.
If you run this at 3840x2160 @30hz via display port you will have no problems at all only at 60hz is where the problems starts but it is fixable by dual display they are other ways to fix it iam sure. I could not install the monitor drivers which was odd from Acer website but not a big deal as everything is working now. Not a 5 star due that flicking problem.
