I want to know if I can send a wireless visual signal from my computer to my TV. I can hook a laptop up with a s-video cable directly to the TV, but I really want to signal to be wirless from my PC to my TV. If so, how much would this cost and how can I do it and what are the parts needed. Thanks for any help anyone can offer.

Many different ones depending on the outputs on the computer and the inputs on the TV:
pc to tv wireless - Google Search

Like Stratmando said, match your inputs. You don't want to get stuck with something that can only do analog when you need digital, or the resolution is not capable of 1080P or HD.

A better plan is to use a media streamer capable of wireless ethernet or wired ethernet
