As the title suggests I have a Dell Optiplex 7010. I also have an Intel 4000 HD card. The first two monitors are linked in via the displayports at the back of the machine (which hook into the AVI slots into the monitor - Samsung SyncMaster SA450
The 3rd monitor (BENQ GL2450-B) is hooked up via the VGA cable/port. When I bring up "Screen Resolution" on Windows 7, the 3rd monitor, in the dropdown, says "Disconnect this display". When I do Ctrl+Alt+F12, I only see 2 monitors
I hope my terminology is write. Hope someone can help me.
