I know you can buy RGB/VGA breakout cables that take the RGB from the dvd player and input to the VGA input of the projector. I wanted to know how this would compare to my current S-video cable and if it was worth the 30.00 to buy this cable? I would just buy regular RGB component cables but my projector dosent have RGB inputs. Any advise would be appreciated. Thanks.

If you mean that your dvd player outputs vga, then yes it would result in a better picture--as it would have a higher resolution and be progressive scan. Also, RGB and VGA are basically the same thing--except the connecters, bnc or 15pin.

p.s. what model dvd player do you have?

No sorry Must have not stated it correctly, My DVD player has RGB outputs But My projector only has Svideo RCA( yellow) and the VGA input, so they make cables that go from RGB( dvd) to VGA( projector) and I wanted to know if That wouldbe better then svideo and how much better? if there is a way to quantify it. Also My DVD is progressive scan It was bought 4 years ago mabe, it was 250.00 at the time. Dunno its Model # Im in a different room. Thanks for any further help.

He's talking about component video (YPbPr) to VGA. Video Freak - component cables aren't RGB. I've been looking at the same problem... my setup will take S-Video and VGA, but not component and most DVD players output progressive scan only through the component cables. I can't give you advice but I would be interested if anyone else has experience with a component to vga breakout cable. There are also component to s-video breakout cables. One of my concerns would be if the progressive output is 640x480 and the native resolution of my LCD is 1024x768... wouldn't that make things blurrier than necessary? I do have a video scaler and deinterlacing box - the Viewsonic VB50HRTV that accepts s-video input and outputs to VGA... so in theory I could get a component to S-Video cable and scale up the resolution. The only problem would be if the VB50HRTV is always expecting interlaced video... wouldn't that mess it up if it tried to deinterlace progress video? The VB50HRTV does accept VGA input, however I think it might be just a passthrough - so that I wouldn't be able to scale up the 640x480 progressive input that comes in on the VGA port. Any ideas?

Their are some DVD players that output a RGB signal. But Component video IS NOT RGB, rgb has five connections, R G B Hs VS. The lower resolution depends on your displays scaling ability. Personally I perfer a HTPC as opposed to a dvd player/scaler.

Ok so what have we learned, I've learned that Im more confused, OK the cable Im looking at has a red green and Blue RCA connectors that go to a 15 pin D sub VGA adapter. And wanted to know if there was any Advantage of using that as opposed to the svideo? Hope this makes for better clarity on this. Mabe not LOL Its all CRAZYYYYYYYYYYYYYYY. L8er

Hummm I think I may have just figured out something, I guess older projectors( 2 years old and more) usually cant accept Interlaced/Progressive in 480i, 480p, 720p, or 1080i at all. I emailed Proxima jst to see what they would say But I think Svideo is what Im gonna stay with. Who knows, I will post back If I learn anything more.

Freak did you find out anything new about this yet? I was wondering the same thing if I can use that adapter and if yes then how is the picture quality compare to s-video. I saw something else exactly like that cable on ebay and he said it can be use for lcd projectors.:scratch2:

this cable wont work with the component output on your dvd. You need a component to vga adapter that is much more expensive. This cable is for monitors or projectors that has "sync on green" So don't bother trying it won't work...
