Weird banding issue on Nvidia 301.42

I recently upgraded my monitor to one of the korean IPSs running on a vanilla gtx 670 and thought i was getting some banding issues watching GoT in 720p. I plugged in my old gateway FPD2485W and saw the same issue, swapped back to my old 6950 and the banding is GONE. Weird thing is i play other video such as Top gear in 1080i and the banding is much less visible. I took some advice and figured out if I disabled hardware YUV->RGB conversion in VLC it reduces the banding significantly, but still there if you look close.

heres a pic of the banding:


over at the nvidia forums http://forums.nvidia.com/index.php?showtopic=227767 some people have been getting the same issue as well and was wondering if anyone here has a fix.
