S-Video or Composite Through VGA

Specs: Windows Vista 64

I have a brand new laptop with an Nvidia 130m gt card. Only Hdmi and VGA out. My projectors only have S-video or Composite.

I was told there is a way to get video from the VGA port with a dongle, but so far, no luck. The VGA port doesn't pump out the correct signal. Any clue to what I'm doing wrong?

I really don't want to buy a scan converter because I need to be completely portable. I was told this card supports TV out, but so far, Tech support from both HP and Nvidia are clueless.

Projector only has s-video and composite? How old is it?

Because you're displaying content on a large screen, you want the best picture possible. Out of the two connectors you've mentioned, S-Video will produce the best image.

Since you're using a low-resolution, interlaced analog connection, you'll have to drop Windows' desktop resolution to 640x480. Set the refresh rate to 60Hz, if it isn't already.

The HTPC:
Pentium M oc'ed to 2.82GHz, 667FSB, 2MB L2
3GB of DDR-800 @ 667MHz
GeForce 9600GT
Blu-Ray
Vista
Modified PowerMac G4 'Quicksilver' case
HDMI to homebuilt 1080p projector

The content will be Music video (640X480) for club usage. No need for higher qaulity. Projectors are great, but not getting new ones (Way too many to replace). Also for school usage... Display class room project on TVs. All the schools I visit have tvs that only have Composite out.

With that said, I did a custom screen resolution of 640X480 and still did not do the trick. Does anyone know what pins (On the VGA port) are used for Composite or s-video?

I'm sure this solution is simple, but no one seems to know what it is.... It's funny that I dropped $2,000 On a new Laptop and it can't be hooked up to a standard tv... Or Can it?

Will a program like powerstrip work?

There is no composite or S-video output on a vga port. I doubt if it will help you, but the following shows the VGA pinout.

Notice what is written about THIS adapter:

"NOTE: Your VGA card must support TV out directly through VGA port function. Please consult with your VGA card's user manual for more information."

I consulted with them. They said it is supported... Obviously not. The strange part is, I can buy a dock that has composite and component.

So this card must support Composite, Right?
