Default VGA -> RCA adapter to TV (will it work?)

I have a laptop with a 8400M card. I can successfully connect the laptop to a HDTV with a VGA input.

But I also have a VCR that has RCA inputs (1 video, 2 audio), so I was wondering if I could purchase a cable like this and connect the laptop to the VCR:


Of course I'll still need a cable for the audio.



Will it work with this setup, or do I need an expensive converter box?

it probably means 1 coax for video, and two classic RCAs for audio like in e hi-fi setup.

It should work except that the yellow plug is a female plug and the one in your vcr is also probably female. So it seems you need a male-male cable in between.

don't make any bets on the signal quality, but it looks like you will get something recognizeable on the tv screen.

You'll probably have to make some custom modelines to make it work. Search the net, as this has been done before.

However, IIRC, it might only be some ATI cards that support that sort of cable, unless there some small circuit inside the VGA connector to convert the RGB signal (3 different wires plus ground) into composite (1 wire plus ground). I doubt you can make a NVIDIA card output a composite signal on the VGA port.

I might be wrong...

This is what I thought first. Maybe the card is not capable and it turns it's a waste of money.
So, any NVIDIA developer can confirm if this is possible?

(maybe I should buy the cable and try it for myself, it's only 3 or so...)
