Does anyone know of a Geforce card with composite or RCA TV/OUT? Most come with S-VIDEO out, but the tv in my room is a POS. The composite out looks decent on my tv playing dvd's off my pc. The only card I know that has RCA out is the Asus V7100 series. The card is decent, but I can't get it to even boot in my AMD box.

Most video cards come with an adapter for s-video to composite, but you can probably buy one anywhere. S-video just uses 2x the number of scan lines, so all the adapters do is run 2 of the s-video pins straight through to composite and end the other 2.

I hope I said that clearly

That's not true at all. The guy at Best Buy must have told you that ;)

S-video keeps the luminance (brightness) and chrominance (color) signals separate. This allows the video signal to bypass one combine/split step in the transmission from the video source to the TV. This allows for a sharper, higher resolution picture because there is less processing happening to the signal. The comb filter in your TV is used to separate the signals when composite video is used.

2 of the s-video wires carry the luminace signal (1 wire is signal, the other is ground). If you connect only those you will get a black and white picture. The other 2 wires carry the color information (again, 1 wire is signal, the other is ground). If you connect just those you will not get any kind of picture. A s-video to composite adapter combines the signals into two wires, signal and ground. This has to be done in a certain way, you can't just tie all the s-video conductors together or just not connect a few and expect to get a composite signal.

Just thought you'd like to know.

Come on Workin', most of them don't know zip, probably if told to look for the color-burst on the front-porch, most of them will open the front window of their second floor apartment, looking out the front-porch. :) :) :)

LOL, but giving 'em a little education can't hurt. At least as far as the basics go, I hate to see people give totally wrong info. I said something about a needle-pulse pattern to someone once and they thought that would really be painful :p :D
