it seems to depend on how old your tv actually is. The oldest type that can receive a pc signal is with a scart adaptor. This has a scart plug with 3 leads coming from it with a red yellow and I think black connector. Next up is usb if your tv has a usb socket a usb cable can connect. The latest I know of is an hdmi socket where an hdmi equipped pc can use an hdmi cable to connect between them. I assume there is such a thing as a wireless adaptor but I have not seen or heard of any.
