This is my second try at this monitor.  The first one was returned due to image tiling and the monitor's inability to come out of standby mode.  Sick and tired of the poor quality of these monitors.  The image quality is absolutely stunning, but the problems that come with it have left me angry and fed up.  If I don't find a resolution in the next few days, I'll be returning this one for it's smaller sibling (catleap 27").  More details on the issue:  If you set your monitor to turn off after x minutes, the monitor will not turn back on.  You see the amber light, but when you press a key to resume the monitor, it does nothing.  So I am forced to reboot.  At the reboot, the monitor is tiling (duplicating) the images in the post and continues the same behavior in Windows.  I tried replacing the monitor cable, disconnecting power cables, etc...  The only thing that works is repeated reboots until the monitor behaves correctly.  NOT recommended.
