Ever since I upgraded to my AMD 6950, I've been having trouble running my desktop in extended mode. Usually, I would work on my main display, then either stream video or playback MKVs on my hard drive to my TV (A 50" Panasonic Plasma). It works, but there is an obscene amount of lag to the point where I can't get any work done while movies are playing back to my TV. There is no lag if I'm running my TV as the main display, only when it's in extended mode.. which is what I need.

Does anyone know what it could be? My old 4850 never gave me this problem and used to work flawlessly

My processor is a i5-2500k @ 3.6GHz btw

Could you take a video to demonstrate the lag, I can't envision in my mind what it would look like?

Also, does it only happen for videos? Or does it affect everything, e.g., dragging a window around?
