Yeah i agree very weird...Right now no i don't have another monitor i will be getting one this weekend though. Another note the monitor will do this even when it is unplugged from the computer. So if the monitor is stand alone it will still have the same issues. The only thing i am really concerned with is that the monitor could damage the new video card. This is a Mac Pro so video cards are not cheap for this thing at all. Do you think this is a possibility?
