Don't forget about audio. Even where the appropriate video output is available, many PC's lack any audio output other than a minijack.

Plug the audio cable into whatever produces sound and you're fine. TV/receiver/pc speakers/whatever. Works for me.

1/8th inch -> standard RCA cable is pretty common I think. I have like 3.

Lots of gadgets throw that thing in for free. Only having 3 is evidence of frugality. There must be 10 of those things around my apartment.
