I have a fairly new laptop with an S Video output and a RGB output (3 rows of pins).
I have a Sony Bravia 42" TV (thanks for the advice here at Tech Talk). It has an "RGB In" input in the PC-In section, but also has an S Video input in the "Video 1 In" input section.
I want to connect the two so that I can watch files that are on my computer on my big TV screen without going through the trouble of making DVDs. Which connection will provide the best quality picture? I have read conflicting information when I did a web search, so I am asking here. Thanks!

Certainly RGB. AFAIK, S-Video is limited to standard SD signal.

RGB, not sure by what margin, but I read up on this some years back and I can assure you of that, I just can't remember the details.

It kinda depends on what type of signal his RGB puts out. If it's just a stadard def, regular 4:3 signal I think he'll have better results with S Video. It's true that a component video signal can be used for high-def formats but is doesn't provide any benefits for non-HD video. So check the output formats for the video card in your computer.

Thanks for the responses. I have a Graphics Media Accelerator X3100 on my Toshiba Qosmio F45-AV411 laptop. I know that the DVD player on my laptop is just a standard definition DVD player. How would I determine the output formats for my video card, as Drew suggested? I haven't been able to figure this out from web searches although the information is probably out there for those who know more about this than I.
If it matters, my Bravia is a 1080p HDTV.

Not sure why you make it such a dilemma? As you said, you have RGB input in the PC-in section of your TV-set, and your laptop is a PC, so Sony kinda answered this question for you.
I don't know what makes Drew think s-video might be better (in whatever definition). IMO, it can't be, unless your hardware is malfunctioning. I'm pretty sure it exists on HDTVs purely for compatibility reasons.

Sorry, I was thinking of a component video output. (A single RCA cable instead of RGB.) SVideo is superior in that case.

I believe that we have reached a consensus in this thread.
I will buy the RGB cable and see if it produces a better picture than the S Video connection.
Thanks for the help, everyone.
