I've had this problem for some time now, and I'd really love to sort things out on this issue : I'm monitoring through a Nvidia card (GTX 470) to a 32 inches Sony Bravia monitor. When I had AERO enable in win7, the tearing I had when working with XP disapeared. Problem with AERO was I had constant freezes during the editing. I disabled AERO and now PPro is running very smooth. BUT, since then, the tearing on the monitor reappeared...
How could I solve this ?
Thanks for your help.
I had screen tearing when I turned aero off (gtx 285, win 7x64). I tried just about everything and the only way to get rid of it was to turn aero back on. It hasn't caused any problems with my workflow though.
I leave Aero on myself. Never had an issue with it.
