8K displays flickering
Question
When I connect two 8K displays to both Thunderbolt ports on the left side or the right side of the computer, they flicker when
they run at a display rate of 60 Hz.
Cause
This may be because of interlacing or switching as the Thunderbolt controller has send only part of the data, where the other
one has to send the second part of the data synchronization may be a problem.
Workaround
Connect each 8K display to a Thunderbolt port on either side of the computer, for example, one 8K display to either Ports on
the left side, and the other to either Ports on the right side. After doing so, power the displays off and on again.
8K displays not displaying correctly

Cause
This may be because of a hardware limitation with the Thunderbolt docking station.

the display.
