sweet!
I also have a samsung 32" connected to my PC. I run resolution at 1360x768 (Native PC input resolution @ 60Hz).
Different TV inputs have different resolution and frequency requirements and so the manual can help you determine the best and also valid resolutions.
Some DVI inputs require DVI-HDCP and will not work unless your video card is also capable of HCDP. If it's VGA, then no HDCP is to be worried about.
If you see pixel jitter, your cable is probably too long, dirty or cheap VGA cable/filter. If you use the S-video, ouch! If you use component, it's better than S-video, but may not be as good as your VGA in quality, but can be better in resolution given your TV has a poor VGA input resolution selection.
There's more to it, but all is well.
If you want to post your resolution and which cable you used, we can confirm that it's the best way or offer another way.
