Beautiful colour, great size easy setup

none that I see


Purchased for a Graphics Designer and she is thrilled with it. I am amazed at the colour and clarity.

High resolution, very good quality, DisplayPort

I wish they had the same model but 28in.


A very good screen for the price. The 2K resolution is really nice upgrade. Once you've tried it, you don't want to go back to a 1080p resolution. The quality is good and watching a movie feels really nice in terms of colour. If possible, use the DisplayPort output, instead of the HDMI.

Great Size Good colour Fast setup

3 dead red sub pixels No built in USB hub Only 1 HDMI input Colour settings impossible to find in menu.


Picked this unit up on sale for $500. I was concerned that some dead pixels may have made it through the quality control at ASUS when I was considering getting extended RMA coverage. When I first set up the monitor I did the colour tests and had to really search hard to find the 3 dead sub pixels (all red pixels). The resolution on this unit is high enough (ie. the pixels are small enough) that I don't even really notice them unless I'm searching for them. Manufacturers warrenty has me covered if I ever get 2 more in the next few years. There is a minimum 5 dead sub pixels before they'll replace the unit. When you pivot the screen into portrait orientation, all your cable jacks will be pointing left. Having the monitor about 1m away from the front of my computer is about as far as the included cables will run. Reviews mentioned that because ASUS does not perform factory colour set up, I would have to do it myself. I spent about an hour playing with the menu's before giving up and deciding it was good enough as is. Probably never going to touch any button besides the power button ever again. I am happy with my purchase and would recommend my friends stick to the 1440 resolution instead of the 4k for the 27" models.

Nice and sturdy Incredibly rich colours Matte black finish Menu is very thorough



Great monitor, viewing angles are great and definitely a huge difference from my previous ASUS VX238H. Robust design and overall an awesome monitor

Beautiful Vibrant and consistent colours Low input lag for fighting games (26ms)



Wanted to replace my 24" and 22" dual display with a 1440p 27" that could handle colour accuracy for my design work and provide the gaming performance I needed. I can happily say I didn't notice any ghosting with 1080p movies or input lag in Street Fighter IV. Definitely worth a look if you're in the market for a best of both worlds monitor. I added a second GTX 770 4GB because 1440p gaming is pretty demanding. I tested it for dead pixels and didn't find any, but make sure you get the 30-day NCIX coverage. The first week is when they happen, if they're not already there and Asus only covers clusters.

- Amazing. That is all.

- Nothing at all


Upgraded from 21.5" 1080 monitors to this. It is freaking amazing and got it on sale, with price match. You need to get one of these. Like now, RIGHT NOW. WHAT ARE YOU WAITING FOR? DO IT.

By: TheBigTroll1226 2014-03-25 18:00

-built like a tank -easy to use -stand is amazing even though its mostly plastic

-price is a little high -would have wanted some calibration done at the factory but oh well


Great monitor for the 1440p uses out there.

Amazing picture quality, nice and solid stand, included cables, matte finish.

Backlight bleeding issues, dust/dirt under the anti-glare coating, poor quality control.


I went through 4 of these monitors and they all had issues. The first one had rainbowish backlight bleed at the bottom edge of the monitor. The next 3 all had dust or dirt under the anti-glare coating. Save yourself some trouble and look somewhere else to spend 700$ on a monitor. Otherwise have fun playing the LCD lottery and dealing with back to back RMA processes. Do not purchase this monitor without the Express Coverage warranty. After all these years with perfect Asus displays, I am now dissapointed.

Amazing picture quality

Dead/Stuck pixels


Amazing picture quality but many of them have dead/stuck pixels or dirt under the anti glare coating.

Excellent Color quality, great massive resolution.

Huge Response time (5ms grey to grey maybe, But when tested it was more like 12ms black to white to black) , Unfit for gaming.


Before owning this monitor i used to have a 27" Asus 2ms NT monitor. and while shopping for monitors i thought that this was an upgrade, a step further for a better (Dota2 ,Diablo 3, BF3, Borderlands 2). But its not. this screen has horrible Response time and input lag, that its almost too annoying to play with. and apparently the 5ms is not really 5ms when tested As a gamer, you will suffer. and even in movies its pretty annoying. but if you do design art and Photoshop kind of work , this monitor lives up to its rep. its pretty good in acquiring an excellent color quality. I am unfortunate to say that i am going to have to return this monitor and replace it with another 27" that is 1080p with faster response time because apparently all 2560x1440 have horrible Response time in general. So If you play any games on constant basis, don't get a 2560x1440in general.
