I have just did a clean install of Windows 7 ultimate from XP and I am unable to get my dual monitors to work like they did in XP.
I have a DVI Radeon graphics card plugged into the agp slot, and a Nvidia geforce vga adapter plugged into a pci slot of my dell optiplex 755. When I am in the screen resolution settings the second monitor cannot be detected.
In bios I have 2 options under primary video adapter and they are auto, and onboard card. When set to auto the Nvidia card gets a signal but the Radeon does not. There are no conflicts in the device manager, and all of the drivers
are up to date.
When I change the bios option to onboard card the Radeon adapter gets a signal but the other monitor cannot be detected and in device manager there is a yellow exclamation mark next to Standard VGA adapter and a code 10 error that states the device could not be started.
I have powered down, and unplugged every cable, I also tried to use the integrated VGA adapter to the Intel G31/G33/Q33/Q35 Graphics Controller but the computer will not even boot. I get
Attention Unsupported Video Configuration Detected"
I have two monitors, both work fine as standalones but Windows will not detect either as a secondary.
Please help me someone, I am so used to having my helpdesk email open in one monitor and all of my other work in the other monitor.
