Hi, I've got an ATI Radeon XPress 200 onboard my Shuttle ST20G5. The VGA port works fine, and so does the DVI. But I'm a tad old fashioned and I'm still on CRT monitors. I've tried to use a Leadtek DVI to VGA adaptor for one of my displays but the drivers simply cannot pick up a monitor on my DVI output and keeps disabling the display. I've also tried a 'generic' adaptor which looks the same. Any suggestions???
The onboard DVI will only output to a DVI monitor, no DVI to VGA adapter support.
I would also suggest Sudhian forums for more help, and I'll post a link to an article you may find useful (you can verify the comment about DVI adapters just above the photo of the backside of an ST20G5).
