SUMMARY
I have three monitors connected to my AMD RX 6900 XT. This setup worked fine
till yesterday. Yesterday only two of the three monitors were active when the
KDE was launched. The third one is visible in Dispay settings (see attached
screenshot), but it's not working and shows wrong resolution (1024x768 which
can't be changed to native Full HD resolution).
The monitor doesn't work even in KDM and the resolution on the other two is
messed up (it looks like 640x480 or similar), this is fixed after login, but
the third monitor still doesn't work.
I tested this on both Wayland and X11.
STEPS TO REPRODUCE
1. Start desktop machine
2. Login to KDE
OBSERVED RESULT
Only two monitors are working
EXPECTED RESULT
All three monitors are working as they should
