yes, because tehre are two types of dvi, the ones that can do that, and the ones that can't. in this case you can't really convert from the analog vga to the digital hdmi without problems (which i didn't know).

Actually the Xbox 360 doesn't have digital output. It's Analog only over Component.
A $10 VGA to Component cable won't work unless your TV specifically accepts RGBHV signals over the Component jacks (highly unlikely).
A Key Digital KD-VTCA3 transcoder ($200 or so) is the best option to convert the VGA 640x480 Dreamcast output into 480p to be input over the Component jacks.

Hey Lyris, I've been looking for a converter like that for a while as my TV accepts up to component video. What would the quality gain be on a 42 inch TV using VGA to composite versus using straight S-Video?
Need a Treamcast, Dreamcast modchip, HUGE DC memory card, ASCII-like DC fighter pad, or Saturn Gameshark with tons of backup memory? PM me.

Der, stupid close-sounding video terms. I meant component, not composite. So yeah, between VGA - COMPONENT video vs straight shot s-video which would look better, and what would be the quality difference?

VGA --> component, would have pretty much no loss as most of it is straight through.
VGA --> composite, would have severe quality loss and is not worht it unless you really need to.

That AD722 IC costs almost $30AUS, so its not a cheap design, I'm thinking of making one though and trying to get the parts through uni so I don't have to pay.

So the difference of using s-video vs using VGA - component would be about the same difference (quality wise) as s-video and VGA , correct? Would this be as noticeable on a 42 inch projection TV where my input options are s-video and component video? Also, would this setup be fine for feeding my PC into my television?
Sorry if 3 posts pop up by me, the last two i put in mysteriously dissappeared.

I wouldn't think you would notice any difference between component and vga. So I would rather turn a vga plug into a compont then use s-videoWould this be as noticeable on a 42 inch projection TV where my input options are s-video and component video?
My mate does this on his 106cm plasma and it looks aswome. (as long as your TV can take the resolution)Also, would this setup be fine for feeding my PC into my television?

Component done properly would give you 480p which is a huge leap over S-Video (which in America has 480i maximum). There's better colour resolution as well.So the difference of using s-video vs using VGA - component would be about the same difference (quality wise) as s-video and VGA , correct?
As Prophet said, between Component and VGA there's hardly any difference (unless your TV is very lousy at handling Component, but that's very unlikely).

Killer, hink I found my next upgrade for the compy and the DC. Saw one or two full on converters on the web for around 120, gotta pick one out. Too bad the all-in-wonders don't have a VGA input or I could just put that cash towards a new GFX card.

Yeah, tried that. The only units I see tha are actual boxes to do what I need start at $140. I'm pretty sure you can't just use the VGA- component cables as I don't think they have the IC in them.

That is different type of component. Their is more than one type, about 6 that I know of. So yea, it does depend on what your TV takes and even where you live. But traditional component is just RGB, and I *think* most newer TVs can tell the difference between them and automaticly ajust to which your using.Lyris wrote:BTW Prophet, just had a better look. That diagram you posted wouldn't work. It just converts RGB to RGBHV. Component needs RGB converted to Colour Difference Video (YPbPr).
Also, the sync is not needed on TV's like it is on mointers. I don't know about overseas but the TV's I've seen don't have a snyc on them (with component that is, obviously SCART can have this). The circuit for combining the snyc is very simple, you just need a couple of resisters, and XOR IC and a transistor.

If enough people are interested in getting this setup, I can try and find us a converter and scam for a wholesale deal. Still won't be cheap, but I can probably save us a few bucks.
