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

Question

When I connect the 8K display to the computer using a Thunderbolt docking station, it disrupts the display of my computer.

Cause

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

Workaround

Connect the 8K display directly to a Thunderbolt port on your computer. Power on the display and than turn off the power on
the display.

Daisy chain two 4K monitor via WD19TB series cannot
reach 4K resolution

Question

When two 4K display is connected by Daisy chain via WD19TB series docking station, it cannot reach resolution upto 4K *2 @60
Hz.

Cause

This is because currently Intel GFX driver disables Display Stream Compression (DSC) support.

Workaround

Connect the two 4K displays by non-Daisy chain method.

Adjust both the 4K displays refresh rate to 30 Hz.
