I have Raedon R5 340x graphics cards and workstations with Windows 7 pro installed. I’ve had no luck getting the workstations to recognize the AMD Radeon graphics cards. They shows up in device manager but the AMD software doesn’t see them. We are wanting to add second monitors to the computers. I’ve re-installed the graphics drivers several times with different versions and updated all of the Dell drivers and bios for the machine. Pleaes advise.
