Possibly related observation: On my 720p TV, if I output (via HDMI) 720p to it, I lose the outer ten or so pixels off of each side of the screen. NVidia video card configuration tool indicated a higher resolution was available, 13??x???, which resulted in a fine picture with no missing pixels, once I switched to it. This was about a year ago. (Can't easily test, now, because I no longer have a PC hooked up to that TV) -- :wq
