Hello,
Build:
CPU: AMD Ryzen 5800X
GPU: Radeon 6600 and Radeon 6400
Motherboard: ASUS TUF Gaming
PSU: RM 850W
OS: Ubuntu 20.04
My workflow requires 4x4K projectors and with at least 1 4k monitor to be running with it. Sales rep suggested that I get a 6600 and 6400. Now the fun part is, as soon as I connect the 5th monitor, a display from the 6400 turns off. Which is weird because I can see all 5 on the Linux system settings.
I have tried having 2 monitors on 6600 and 2 on 6400, it runs fine. But when I connect another, one seems to just stop displaying things. I am not sure what is causing the issue and how to fix it. AMD Support can't help me after sale coz they're trained only in Windows.
