I am still facing the issue, this time I can see the 2 external screens as
"disconnected", even if they are connected, and with a resolution listed
for both.
DP-3-1-1 disconnected 3840x2160+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm
DP-3-2 disconnected 3414x1920+0+240 (normal left inverted right x axis y
axis) 0mm x 0mm
3840x2160 (0x540) 519.940MHz +HSync -VSync
h: width 3840 start 3864 end 3880 total 3900 skew 0 clock
133.32KHz
v: height 2160 start 2163 end 2168 total 2222 clock
60.00Hz
Trying to "remove" the monitors is throwing an error. Trying to remove an
empty one failed as expected.

Any idea what I can look at?
