I have 2 AMD Fire Pro W4300 video cards used for 8 monitors. I Installed Windows 10 Pro 64 Bit. Only 7 monitors were working and 8th monitor would not come on.
Changed around the monitor connections, no effect.
Installed Windows 7 Pro 64 bit on exactly the same hardware. All Monitors are working perfectly.
I want to go back to Windows 10 Pro 64 Bit.
