Hello... I'm trying to get my pc (a rugged mobile vehicle computer) connected to displays that are already installed in a bus.

The LCD only has a composite video in plug (RCA) so I bought a couple different VGA to composite/s-video converters and my PC has a 800x600 resolution that looks awfull using both converters.

Would other resolutions improve the image?

What am I missing? Is there a specific piece of hardware that converts VGA or DVI (which is on my PC as well) to composite video? Or do I need to replace the LCD's on the bus to something newer?

Thanks, This is driving me nuts.
