But most gamers turn off all motion processing. I can't tell if you tried that as the formatting of your post is a single paragraph (hard to read.)
There's also some issues with some Xbox's and that problem description.
In short, motion processing off and game mode on.
I recently got a hold of a 46inch LED Samsung (6000 series) and it is unable to cope with my xbox 360. The pixels jutter quite frequently when playing games such as far cry 3, battlefield 3 and halo 4. I know for a fact that the motion plus settings are making very little difference (smooth is the best setting but still a large amount of jutter). And I noticed that the hdmi cable I was using was only a 6. Something Gbps, so I bought a 10.2 Gbps and though it may have improved it vastly, the jutter is still frequent in the upper half of the tv. my question is, would upgrading to a 15.8 Gbps hdmi cable make any difference or am I stuck with a Tv that cannot cope with the frame rate? I'd also like to know if other people are having similar problems and how they dealt with it.
