I made a separate thread about this too, but I thought it might get read more in this thread.
This is an odd problem but I don't know too much about the TVs and I was hoping someone here would help me out. Be easy on the new member .
Anyways, whenever the TV is trying to display a quick moving texture that is somewhat intricate like highly detailed gravel or grass the textures get noticeably darker while they are in motion.
I have included a video of the problem. Pay especially close attention to the terrain in this video, you'll notice that while standing still the terrain looks normal and as soon as I look around the terrain gets dark and then returns to normal brightness/tone when the movement stops. I've noticed this happening more pronouncedly when games (starcraft 2, skyrim, modern warfare 3 and Deus ex:hr) are in 1080p and less so in 720p.
I'm on the fence about exchanging it for another TV or trying another unit of the same model if this is not a normal phenomenon.http://www.youtube.com/watch?v=w85xqbKZ3VA
