What Use Is a VGA to S-Video Adapter
I bought a VGA to S-Video Adapter to enable me to connect my laptop's VGA
output to a Projector via the S-Video input on the projector. (The projector has only the S-video input.) The adapter is a 'y' type device with a S-Video jack and a composite (RCA) jack. It doesn't work. I examined the pin out of the laptop's VGA and the pin in/out's of the adapter. Pin 2 (Green) of the adapter connected the Chroma pin of the S-video and pin 3 (Blue) connected to the Luma. This was true for two other so called adapters. How can that be expected to produce a signal the projector can use at its S-video input? What possible use does this type of so called adapter have? |

A "VGA to S-Video Adapter" is a Scan Converter not a cable, UNLESS, the cable is something supplied by the manufacturer to support a form of "TV Out" for their device. It has to be the particular cable for that particular device, no other cable will work. To have any useful reply to your post you would need to include the Make&Model of each of the "VGA to S-Video Adapter"s that you bought. Luck; Ken |

What Use Is a VGA to S-Video Adapter
I bought a VGA to S-Video Adapter to enable me to connect my laptop's
VGA output to a Projector via the S-Video input on the projector. (The projector has only the S-video input.) The adapter is a 'y' type device with a S-Video jack and a composite (RCA) jack. It doesn't work. You need a VGA card that support that mode of operation, and it's not easy to find one. Most modern projectors have D-Sub or RGB in.... How old is that projector? What other interfaces does it support? Buy a video converter. It's more expensive though. -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

What Use Is a VGA to S-Video Adapter
I suspect that you bought a dedicated adapter designed for use only with
some video cards that actually had S-Video signals present at the VGA connector (which is not standard). A generic adapter of this type would be very complex and expensive and would not look like a cable .... it would be an active device and, among other things, would need a power supply.

Thank you.
I suspect you are right, Barry. I now have a converter and cloudy skies are now serene. "Barry Watzman" wrote in message ...
