probably. it depends on the outputs on your video card and the inputs on your tv. probably your video card and tv both have dvi ports - that's your best bet. if you have hdmi or component out on your video card, that'll do too. most video cards have s-video, and that'll work but not at a res over 480i, i think (i'm just guessing the lcd tv is hd -otherwise, s-video is fine). other than that, it's just a matter of getting the right cable and wiring it up.
i think there are dvi to hdmi converter cables available, too.
if you're using motherboard video on the computer, a new video card with the right outputs would be a lot cheaper than a blu-ray.
