I have a Optoma pro 250dx dlp projector. I have a computer with component option pushed through the seven pin s-video port on the video card. This then goes into my Sony AV Receiver, then it goes into a component-vga cord into my projector where the projector reads the component signal in the vga1 port. I also have a dvd player component into the AV receiver then to the same cord to the projector.

Problem is that when using the computer, I get ghosting, but the DVD is perfect (so it can't be the cord) and the projector menu is perfect. My computer is older, so I am first to suspect the ability of the video card to do a good job.

Any thoughts?

The S-Video cable from the computer to your receiver is where I'd start. Can you use another interface? S-Vid from a computer is most times not a desirable option. What inputs types does your A/V receiver have to work with? Any VGA?

Whenever I have a problem with ghosting I suspect Indian burial grounds.

Using an S-Video cable to connect your PC to your Receiver is going to give HORRIBLE results. S-Video was designed for old analog TV's with real resolutions of 320x240.

You need to at least go to a Component (3-Wire) connection in order to get good results.

It's toe-tappingly tragic!
