...Need help again!!!
I finally bought a MSI Radeon RX 560 card for my cMP 5,1 under HS. And I decided to downsize from 6 to 4 monitors for a while. I replaced one of my 2 Radeon HD 5770 cards with the RX 560 and everything is working just fine (so far) under HS.
But a problem arises the moment I switch to my Windows partition. Under Windows 10, the monitor connected to the RX 560 works fine but I have a problem with the 3 other monitors connected to my HD 5770. I uninstalled the previous drivers, downloaded new ones: same problem. I rebooted without drivers: same problem: the image on the monitor with the RX 560 behaves as expected (display, resolution), but only 2 of my 3 monitors connected to the HD 5770 are working, and the resolution is downgraded to the basic. On top of that, the two are acting as one (as a mirror). The 3rd doesn't show any image. It's like the 2 cards don't want to work side by side under Windows 10.
Any idea to help me with that problem? Anyone?
