I have a CRT connected to a dvi connector on a videocard using a vga cable and a dvi to vga adapter. Now I cannot set the refresh rate to anything decent (only 60Hz and lower). I've hat this happen using different CRT's, graphics cards (although all ATI, both agp and pcie), and operating systems (both linux and windows). Any idea on how to solve this, maybe some bios setting?

Thanks

Are you able to set the refresh rate higher when it's connected over VGA? There's no guarantee that all CRTs are capable of 75hz or 85hz. – Darth Android Jun 2 '10 at 10:21
do you have the same problem if you connect via VGA (assuming you have a VGA port to test with)? what resolutions are you using? how old is the CRT? (high-res settings and refresh rates are typically the domain of the video card drivers; bios has nothing to do with it.) – quack quixote Jun 2 '10 at 10:22
I used to be able to set the refresh rate higher over vga when I had a videocard with a vga output. One crt was able to reach 1152x864@100, the other 1024x768@85. The former is 12 years old (production date might be a bit more), the latter I don't know, probably 8 to 10 years or so (it certainly saw a lot less uasage). – Ernst Jun 2 '10 at 13:15
