In that case, all the 3 monitors would get the normal pictures while running "testdisplay -m". But if we boot machine with two or even three monitors, the issue doesn't occurs. The issue exists on both mobile and desktop platform.

Can you please also append the dmesg (with drm.debug setting) of the working 3 monitor configuration?
Created attachment 56732 [details] The dmesg when the 3 displays work well.
I think the latest -testing branch has the fix of this issue.
