I would try lower resolutions til you find what the tv likes. I have a Samsung 1080p tv that my computer is hooked up to and 1080p lookz like crap. I have it at 720p and it looks good, not only that, my video card can easily handle that resolution for games. On my old 1080p tv, a Polaroid, 1280x1024 is what looked best from the computer. Now on both Tvs, BR and Cable HD channels look great, just the computer didn't. I did read that on the polaroid if I forced a 28Hz refresh rate it would have handled it just fine at 1080p, but I never tried that, gave the tv to my parents to use as a tv long before I read about it. But for what it's worth, there it is.
