Sup homies. I just got home from college and set up the computer next to a big screen HD. Thing is, I don't think my video card is made for HD (GeForce 6800). The S-Video will show a picture, but when I have the aspect ratio on the screen at 16:9, I can't change the resolution on the computer to fit with it. It just makes everything all stretchy. Definitely a bummer. Anyway, the adapter that comes out of the video card has many plugs on it: I'll list them in case it helps.
