I have an Acer X223W monitor on 1680 x 1050 resolution. Whenever I go to watch any youtube video on fullscreen, the entire screen turns grey with a diagonal line. However, I hear the sound in the background. I think its my monitor's problem. any suggestions?
I have the same exact problem. Apparently it has to do with your video card and not your monitor. Allow me to direct you to the following forum where the same issue was discussed and a workaround posted: http://forums.amd.com/game/messageview.cfm?catid=260&threadid=90472
