Finally got all the HT elements together three weeks ago, LT150 92 wdhi-power and new dell 1.3gh with radeon 32ddr card. Picture is jaw dropping fantastic, even the wife was won over and has become an enthusiastic fan. Had a couple of friends over opening night, and one had to walk behind the screen (it's free standing three feet from the wall), because in his words, he had to make sure there "isnt some big ass picture tube behind there. after about 20 hrs of watching no one has yet seen rainbows or dithering, probably because every time we have about three glasses of wine or similar libations (those of you prone to rainbows, try it). Here's the problem. Ibegan to notice jerking and some tearing on slow horizontal pans. Went into radeon display menu it showed the "optimal" refresh rate being used. Went to 60hz, the picture became blurry. Walked up to the screen showing the desktop and noticed shadowing onto the pixels to the right of those being used for the wording. At 85 hz the shadowing disappeared and picture became razor sharp. But at that rate have the stuttering at times (dma is turned on). Has anyone else experienced this problem with an lt150 and htpc, and any ideas as to why the shadowy blurring at 60hz.
