if you have a newer computer and a newer HDTV with a dvi port you could connect your computer via a dvi port (provided your video card has one, if you have a video card) If you're using an older tv you may have to try S-Video (looks kind of like a ps2 port) which your video card might also have. If you're using onboard video you're probably out of luck because those usually only have VGA port, but i guess you could also get a vga to dvi adapter allowing you to connect it to a HDTV. Basically it's going to be pretty difficult if you don't have an HDTV with the correct ports. But it is overall possible.
