Question : Problem: Connecting a laptop to a TV

What are the various ways to connect a laptop to a TV - some ways have higher resolution that others Ive heard.

S-Video is one  (usb to svideo cables available on ebay)
And VGA is another

Which has better resolution.
Is there another way?

Answer : Problem: Connecting a laptop to a TV

You should aim for the highest resolution that can be handled by both your laptop and your TV.  In descending order from best to worst quality, I would rate the transport mechanisms as follows:

HDMI/DVI
VGA/RGBHV
Component
S-Video
Composite
RF

Digital is the best, and for the analog methods, the more separate signals you have, the better it is.  Note also that Component can handle high-def resolutions, S-Video can only handle up to 400 lines, and Composite and RF can only handle 240 lines.
