VGA->SVideo/composite passive converter?

post #1 of 4
Thread Starter 
I am trying to deliver an S Video or composite signal to a television via the HDMI or VGA out of an HP laptop. Is there any way to achieve this without purchasing an HDMI television, another laptop with SVideo out, or an expensive active converter box?

Edit -

Upon further investigation, it looks like VGA -> SVideo cables are a scam, and the NTSC/PAL television signal will absolutely require an active conversion to work. Looks like my HTPC on the cheap is overqualified for my television and I'll just have to wait to buy a new television.

I'm not that interested in shelling out $100+ to convert my laptop signal DOWN as a stopgap until I get a TV with an HDMI in.

Edit -

It looks like the HD3200 does NOT support TV-OUT via VGA and I'll need an active converter.

I seem to remember reading that the VGA output would have to support S-video (not sure on all the details though).
I had looked into this when I was building my HTPC since my TV is still a CRT TV, and a 7100 onboard would be enough to do what I needed, but no intergrated had s-video out.
I just ended up getting VGA card with S-video instead of trying to figure it out.

The cable you listed are only compatible with a very slim amount of older cards (All ATI IIRC) that can display S-video over VGA. Many people buy this cable thinking you can simply use it to make S-video come over VGA but this simply isn't the case. You need a compatible card, and they are slim pickings.

You would need an active adapter to convert to S-Video. They are expensive. Sorry for the bad news.

I'm using a laptop that someone abandoned, all I needed to do was take it apart and reseat the inverter. I haven't seen any S Video or composite out expansion cards.

Anyways, I think that some cards will output SVideo via the VGA port, but only if they support "TV-Out" via VGA. I'm trying to find out if my HD3200 in the laptop supports this.

If so, I'll try the $10 adapter.

Yeah, if that happens I'll just go about planning my true HTPC and sell or use this laptop for another purpose.

I got real excited for a moment last night
