Summary: I spent a lot of time looking into which monitor to purchase. I have been incredibly impressed with this machine! The color reproduction is incredibly spot on for a monitor that costs under $1000. The added benefit of having multiple ports to utilize is excellent. The idea of having some of the features available (rotating screen, and layout overlay) was really appealing, though in the grand scheme, I will probably not really utilize much. That said its a great monitor.
Summary: I have little to add on top of other reviews. I just want to mention that the side USB ports are powered down if you power off the monitor. I had a trivial reason for briefly shutting off my monitor. When I resumed power (and my work), I realized I had lost my connection to my encrypted USB drive. :-b This seems unnecessary and potentially problematic. When I do overnight backups to my USB hard drive, I turn off the monitor to save energy.
Summary: As others have complained about the PA246Q, mine started to flicker. It goes black for a half second. It does this many times an hour, which is super-annoying. I got the same results with the monitor attached to 2 other computers. I saw other people on the internets complaining aout this problem (see examples on youtube), so after doing everything Asus support suggested (via e-mail), I returned it to Asus for repair.
Summary: The colors on this monitor are bright and vivid: it astounded me when I first turned it on. The colors were so incredible that even some games looked as though they were being presented in 3D when, obviously, this monitor does not have such a function. Awesome tilt control and ergonomics, with a lot of ports and options for the artistically inclined. However...
Summary: When your computer goes to sleep or into idle mode, somehow the monitor looses connection and starts flickering, it takes an amount of troubleshooting to get the image back. I need Asus to replace this monitor, and in all honesty I'm not happy with the performance of this product. I would NOT advise anyone to purchase this item unless Asus fixes the problem.
Summary: I'm loving the monitor. Side by side with a much older and cheaper LED on VGA connection, it's really a treat. If you're new to hooking up a digital display, use the HDMI cable only - it's the one they don't supply! Otherwise you will not be digitally connected. So order a cable with it. The PA246 is much warmer than the old one, and ahead of me is the whole calibration fun.
Summary: I owned the PA246 since december 2011 and it barely made survived 10 months. It came with quite a few hot pixels, and the lower left corner was hotter than the rest. I could sorta live with it. And then out of the blue, it just didn't turn on. I mailed it to Asus repair in Fontana, CA, quite within warranty (a supposed 3 years) and they refused to work on it. When I asked them to sell me a discounted refurb model, they refused.
Summary: Owned since dec 2011, it barely survived 10 months. Plenty of hot pixels & the lower left corner was hotter than the rest. I could sorta live with it. Then out of the blue it just didn't turn on. I mailed it to Asus repair within warranty and they refused to work on it. When I asked for a refurb model, they refused. They stopped responding at some point. To top it off, they next dayed my broken monitor back to me.
Summary: I am what you could call a semi-professional photographer. I received this monitor today and installed it. I set it on Adobe RGB mode, found my color-Munki and did a quick calibration. I have to tell ya, I was blown away! This is a GREAT monitor! UPDATE - After using this for a few months I am still impressed. It replaced a Viewsonic that I was using as my primary monitor. With the Viewsonic it was kind of by guess and by-gosh!
