It says on their webpage that the maximum horizontal resolution is 800 lines. Does this mean that it can't accurately display 1080i HDTV? Also wondering what this set does to 720p material (xbox)?? Does it upconvert to 1080i, or not accept it at all? Also, the Toshiba 32" HDTV ready tv that I am considering advertises a max. of 1000 horizontal lines of resolution. Is there any advantage to this over the 800 in the Samsung set?
