Video Signal from Desktop to TV

My customer has a Demension 4600 desktop with Video output on either a S-Video or DVI output. his Sony Plasma TV does not have DVI input. S-Video really does not do his system justice. Are there any other alternatives to increase resolution on the TV for a better picture? Is there such a thing as a DVI signal adapter? Also, in order for his signal to be routed to the TV he has to right click on the desktop and choose properties and select the secondary source for outgoing video then basically reboot and then his secondary video output then becomes his primary video where he has to look at his secondary output "TV" to manipulate the programs on his computer while using the TV as the video output. Is there any way to make this an easier transition or share video output to both secondary and primary outputs?

Upconverting does not usually give good results.  If the TV hav component inputs (not composite), you could get a transcoder from Audio Authority or Key Digital and take RGB (aka VGA) output and convert it to component.  This will be better than s-video.  The ranking in picture quality is typically

- DVI
- RGBHV or VGA
- component
- s-video
- composite
- RF coax

In general, the more separate signals you have, the better the picture.
