yeah, as long as you get a tv tuner with "game mode" to eiminate lag, but yeah, i don;t think any of them can do that with an hd signal yet, you;d get some lag and its going to look like garbage in sd. I'm running one on my 22" at 1680x1050 and I ahve to run it at 1280x1024 widescreen mode thought the vga adapter, and it looks even a little fuzzy at that rez.
