Pray that you get a good one and don't ever have to deal with ASUS
11 April 2014
Summary: To start off with I have to say I loved this monitor for the time that mine was without defect. It took me two tries to get one without a defect. So I was happy for about 90 days until the monitor developed a bright blotch against light color backgrounds in the lower right corner. This blotch was about the size/diameter of pencil eraser. So I started to get the RMA process going with ASUS.
Summary: I had to return this monitor as when it woke from sleep the display would flicker/flash blank or jig right by like 1/2 a screen overlayed for sometime until it seemed to "warm-up". I searched around and saw that this was a common complaint. I replaced it with PA249Q 24" which doesn't exhibit the issue.
Two seconds of blackscreen every 10 minutes on DVI and HDMI

Summary: The monitor looks great. But like many many others I have experienced the flickering and blackout (total loss of video) for 2 seconds at random times. I am using the included hdmi, DVI and 2 of my own DVI cables. I connected to two different computers and had the same outcome. I should have taken the other reviews to heart. Please do so, and save yourself the trouble. Photographer, Graphic designer, Technical Systems Analyst, 35 years a computer user.
screen flicker problem on 2 monitors & color drift problem

Summary: I've purchased two of these PA248Q monitors and, sadly, both had the infuriating flicker problem. FYI, this causes the screen to go blank for a second or two -- sometimes several times an hour, other times every minute or so. Very irritating. The online forums say the problem only affects the DVI port, not the DisplayPort. I don't have a DisplayPort card so I'm out of luck. I RMA'd one of the monitors to ASUS. That was not a satisfying experience.
After 3 months screen started blacking out. Others having same problem.

Summary: I put on 2 other monitors and did not have this problem. So its not the video card or cable. See all the other people having the same problem. Read the comments under the video. There are other places on line too where there are many complaints and Asus will not fix it. http://www.youtube.com/watch?v=OrOaj15QwGs This guy tried everything but couldn't resolve it because they didn't think it was the monitor.
Excerpt: I had really high hopes for this monitor. Unfortunately, like many others reported, after the monitor was powered on for a little over an hour it started flickering and blinking on and off. I tried different DVI cables, different power source and even updated my graphics card drivers who no improvement. I would not recommend this monitor and will no longer be purchasing any ASUS monitors. B&H was very good about processing the return.
Pros: Adjustable Viewing Angles, Ergonomics, Large Viewing Area, Small Footprint
Cons: Blinks On And Off, Flickers, Unreliable performance
Summary: What grief this was. Colour cast differencial left to right, clump of dirt in the screen which on first look seemed like dead pixles but on investigartion by an expert turned out to be dirt in manufacture of the panel. This would have no chance of passing Asus quality control so I have to ask "Where do these come from?" And looking at the price, it doesn't take long to work that out, proving the old adage, you get what you pay for!
Summary: This product was delivered without a UK power cable despite the product details clearly stating it should have one. In my travels around Amazon customer reviews this is not an uncommon problem. It had to be returned for a full refund but, despite being booked, the courier failed to turn up to collect it. Amazon had to arrange for a different courier. Result, 3 wasted days and no monitor. This is the second time I've had this problem with Amazon in recent months.
Excerpt: Повелся я на IPS, сейчас жалею, зрение заметно ухудшилось за 2-3 недели работы при 8-10 часов работы за этим монитором... до этого был асус 22 дюйма какая то старенькая модель года 2008 за 6000р брал работал за ним в том же режиме, но он не так нагружал глаза... сейчас монитор не вернуть более 2 недель прошло, да и претензий нет по качеству монитора.
Summary: In precedenza avevo acquistato il HP ZR2440w, che ho trovato discreto, ma me ne sono disfatto (regalato) perché i bianchi presentavano una eccessiva granulosità fosforescente che mi stancava la vista; per il resto il monitor era robusto e ben costruito. Ho reinstallato il mio vecchio e buon NEC P221W, di qualità professionale, ma di 21,5 pollici e risoluzione non full HD.
