I didn't have this issue with the same monitors and an nvidia card, so it s=
eems
specific to the amdgpu driver.

The monitors seem to lose signal (which is normal), then perform an auto in=
put
cycle which then wakes the monitors back up.  The backlight will come on and
display the mouse cursor on a black screen.

I experience this with both Xorg and Wayland.

Unfortunately I can't disable auto input on my monitors, as the previous
workaround suggests.  Just disabling DDC/CI didn't help.

Adding amdgpu.dc=3D0 to linux cmdline resolves the issue for me, but I'm
concerned that may preclude my system from gaining newer features.
