I have a Radeon HD 5570 graphics cards. The card has 4 DVI connectors. All of my workstations have no problem with using 3 monitors except one. I've had to reinstall the OS on this box but when I connect two monitors all is well. As soon as I connect the third monitor I lose the second. The special AMD Catalyst Control Center software does not show three monitors connected it only shows one. As soon as I disconnect the third monitor, two monitors reappear and the control center show two monitors connected.
Is this a Window 7 setting that I have to turn on? Is there some kind of AMD setting that I have to turn on? All of the other workstations with three monitors had no problems.
Any help would be greatly appreciated. Thank you.
