I have a client that has an HP Z400 workstation that has a ATI Firepro V5800 graphics card in a Windows 7 machine. Both monitors were working fine and the display was set to Extend these displays. The user ran some Windows updates and now it acts like there is only one monitor but puts the display on both. I mean the display on monitor two is the exact same as monitor one.

Only one monitor shows up under display. Nothing happens when I click on Detect. When I click on Identify it puts a 1 on both monitors.

I have unistalled the Windows updates and completely uninstalled all AMD drivers and software. When I reboot and it comes up with the default Windows drivers it still acts like they are both one monitor. I am really confused and don't know how to fix this.

The first monitor is plugged into the HDMI port on the graphics card. The 2nd monitor is plugged into one of the DVI outputs.

In Device Manager there is a yellow triangle next to ATI FirePro V5800(FireGL V) under Display adapters. The properties of that has a Device status of Windows cannot initialize the device driver for this hardware (Code 37) 

Please help.

If Windows can't initialize the driver, it will just use its own generic drivers, which will limit performance as well as your multi-monitor capabilities. Have the user run Windows Update manually and keep checking for updates until it comes up as completely up to date. Then download the latest FirePro drivers from and after choosing your language, do Uninstall->Express. Let it run through, restart and run the file again, choosing Install->Express this time. Restart again when it's all done, and Windows should be able to use the driver correctly, and you can extend the monitors in the Catalyst Pro Control Center once the drivers are being used correctly. Good luck!
