Question: I want this monitor!  Anyone use this for gaming?  Drawbacks, if any?
Document: 30&#34; color calibrated... Unspeakable. Perfect for photography, or graphics design. All ports work flawlessly, stand is designed sturdy and functional. Highly recommend this monitor for Photographers, or anyone who does graphic design, or even gaming, the resolution and quality is phenomenal.
You get what you pay for going from a 27&#34; Asus led monitor this thing is huge in comparison. The color and clarity is amazing i was going to go with a 3 monitor setup for mainly gaming but this does what i needed it too and for about the same price as 3 monitors. If you want great quality for the money and can afford this i would recommend.
I wish it did not have the antiglare but you get used to it once the adjustments to brightness and so on are made. I guess the U3011 was meant for office work instead of gaming and they did not want to make a version without the annoying antiglare.
For a much bigger monitor one might use to watch video or play games or do graphics work, the anti-glare coating is an absolute deal-breaker. It makes everything look dirty and grainy. I really have no idea how anyone finds this acceptable. Beyond that I could not find an acceptable middle-ground brightness setting. It always seemed either blindingly bright or disappointingly dim. Keeping the dynamic brightness setting on was cool for video, but then for web browsing everything was way too bright.
PBP (Picture By Picture) allows you to watch TV (HDMI1, HDMI2, or Component) in an window to the left of the current input; I would find it more useful if I could watch a second computer screen there, or a portion of two screens at full res better still. There are some assignable shortcuts that I want to learn how to use (and will update when I do).Now we get to my only complaint in the monitor.
What I do notice is that my frame rates are pretty poor when I play the latest games at native resolution and with all the eye candy turned on. I currently use a AMD 4890 video card and it cannot really push the pixels the way I want. I have a GTX 570 destined for this monitor. We will see if that is enough to play the latest games. Would I suggest buying this monitor? Maybe. Although I love it, one of the 27 WQHD monitors might suffice.
I use this monitor for web development as well as gaming, and it suits both quite well. The lag is not an issue for me, and I play at rather high frame rates(>~60fps).OSD : The on-screen display is very functional, as good as one could get, I must say.
I've owned the monitor now for roughly 5 months and haven't had any problem. I use it mostly for video gaming, viewing streaming video, and general computer use. For those purposes it's been extremely nice. I like the big screen and the fantastic resolution.I am not proficient enough to try and get some sort of precise color calibration for the monitor.
edit:  a lot of people upset with my negative review (inevitable for expensive things). I'd like to clarify that the limitations of HDMI are not the fault of this monitor, and this monitor should in fact be used only with a desktop computer. However, as with many users, I do not have a desktop computer - I have multiple laptops and gaming consoles which use HDMI only, and are not able to take advantage of this monitor's high resolution.
That said, I have been convinced since it arrived and has been in use constantly (I use it for work all day plus nighttime/weekend gaming) that it was worth the price, to me. It is up to you for your use and requirements for color/clarity.Summary:I went from a commercial/graphics artist Planar monitor that burned up in a house fire to this monitor (Planar no longer makes larger 16:10 aspect ratio screens) and have been thrilled...
Answer: I've been using this monitor since last November and I haven't had any problems with gaming.  I am not, however, extremely sensitive to ghosting, lag or color reproduction, and I have not noticed anything like that.  I do not play a lot of FPS - mostly Skyrim.  Hope that helps some.
