Nice advice, I'll see if it work for my nvidia card in my living room system. It also stretches, but using TVTOOL. (Which is AMAZING if you have an NVidia card, it's a must!) It also un-stretches when returning from hibernation. I'll try to test and post my results. I think I remember reading elsewhere that it was a problem with Windows, however.
Good to see you got yours working, though!
