I just bought a desktop that has this chipset for graphics and I'm trying to hook up a second monitor. The first one is through VGA, the second one through the DVI port with a DVI to VGA converter. However, it's not detecintg that port / monitor.

I've verified I have the latest drivers etc

Any ideas on how to solve this?

You need more information. What is the motherboard model. Are these integrated graphics (well the MB model will tell us that :) )? What driver is the Video Card running and which version is it. Where did you get the driver from. Windows update I know messes this up sometimes with their suggested driver....specifically on the DVI port... Also what is the monitor model. I have an Intel integrated H67A-UD3H-B3 and if I instal the windows suggested Intel integrated driver update it ruins the DVI port and I have to plug D-SUB and uninstall the update and reapply the driver that came with the MB –  Campo Jun 9 '11 at 20:42
    
I have experienced at least one graphics device that did not appear to support two analogue devices at once even though it had both VGA and DVI-A... this may be the problem in your case. –  jcrawfordor Jun 10 '11 at 0:14
