Monitor/TV with Firewire input?

I used to think s-video looked pretty good too. But last winter we were experimenting with a big 12,000 lumen DLP projector in the theatre on a 40' wide screen. I was feeding QuickTime output directly from my PowerBook's s-video port to the projector.

The projector's native input was RGB, and adaptor jumpers were used for s-video. After running some footage, we switched and used a cable from the PowerBooks VGA port to show the same video. There was a HUGE difference in quality. The contrast was better and the colors were much more saturated. The s-video looked much worse.

So do you think that was just some odd behavior of the DLP projector's interface? I assumed it was the better quality of the VGA signal, which I also assume would be like a component video signal. Elsewhere I've read that the Sony WEGA TV's will produce much nicer images when driven with component video as opposed to s-video. Haven't had any way to test this myself, but would like to hear from someone who has tried it both ways.

Outputting computer signals through a VGA port is the only right way to go for digital displays. The rescalings and color encoding/decoding proces (NTSC and for shure PAL) allways introduce severe quality losses

>Gints, don't forget that DVD recorders first convert the DV signal into MPEG2

Awwwwww. That sucks !
