Just to post an update, I have had the HP ZR2740w for a few days now and it works great, not a problem. Colors are beautiful and the back lighting is evenly spread, no bleading at all. The only trouble is that when the usb hub on the monitor is plugged into the motherboard my webcam, also plugged into the motherboard, stopes working. But the hub works perfectly, its just dissagrees with my webcam. I don't need the usb hub on the monitor though, so it is not a problem for me. FYI: the webcam is a Logitec Orbit AF.
But its a great monitor at a great price, 9 of 10 for sure.
