If you have S-video, it is simple and good quality. Other than that, it will suck. My buddy hooked his up to his computer once, using an RCA cable to go from the composite out to the video in on the TV. The res really sucked, but it was bearable. He would do that if we wanted to watch a video from his computer on his TV. Just get another monitor, and throw another vid card in there, and run in dual monitors. There will be no resolution lost, and it will be the same as hooking it to your TV. I have dual monitors set up, and I use one of them as my TV.
