Excerpt: When I bought this from B & H, I was quite excited about it. But it quickly began to go quirky on me. It would turn off, then on again in a few seconds. The more I used it, the more it did this, and the more it heated up, the worse the problem became.
Summary: Asus has the worst customer services I have ever had the displeasure of contacting. My product broke and they are making ZERO effort to replace it. If you want to be lied to and sent in circles, spending hours on the phone with people unable or unwilling to help this is the brand for you.
Summary: I bought this monitor and for a few months it was amazing. Then it started to flicker. And by that I mean briefly, for a split second, the display would go all black and come back on again. I did everything I could to troubleshoot the problem. Called support and shipped it back.
Pray that you get a good one and don't ever have to deal with ASUS

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.
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.
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.
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.
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.
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.
