Same problem, sort of... I have an onboard vga port and a pci express 16 dual monitor graphics card with an adaptor for two monitors. I have enabled the onboard port in the BIOS to run with the PCI port, so I should be getting three monitors. I'm only getting two, and they are from the PCI adaptor and running extended as they should. I have downloaded ATI Catalyst Control but can't get the third monitor to come up.
