My cable company will upgrade me for free to an HD cable box, so I was thinking of going HD. The HD cable box has an S-Video out, and my Dell monitor has an S-Video in, so I was thinking I could just use the monitor as a TV instead of buying something expensive. Would that work, or would I also need additional converters? The other issue is that the monitor doesn't do audio, and all I have are bog-standard computer speakers -- how could I get the audio to work without investing a lot of cash? Thanks!
