Dell Optiplex 790Two hard drives. Win 7 installed on 1st drive. Configured with 3 monitors. 1st monitor is connected to the onboard display adapter (an Intel device), 2nd and 3rd monitors are connected to a VisionTek Radeon X1550 card. This works just fine.Installed Windows 8 Ultimate on 2nd hard drive in a dual boot configuration. Windows 8 can't seem to find the correct driver for the X1550. Device manager shows "Microsoft Basic Display Adapter" with an exclamation icon: This device is not working properly because Windows cannot load the drivers required for this device.I've tried installing the ATI drivers being used by the Win 7 side of the computer, but Windows says that it already has the best driver installed.Is it possible that the X1550 is just too old to work in Windows 8?Thanks,Jim

Follow-up to my own posting.I went back and tried again with 10-02_legacy_vista32-64_dd_ccc. Downloaded and installed it. Then, went to CL_95951.INF in the ...Packages\Drivers\Display\LH_INF folder and selected Install.It works! Everything went black for a vew seconds, and then all 3 monitors lit up with the desktop extended to the two side monitors.Jim
