3 Troubleshooting 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 run at a display rate of 60Hz. Cause This may be because of interlacing or switching as the Thunderbolt controller sent only part of the data. Workaround Connect each 8K display to a Thunderbolt port on either side of the computer, for example, one 8K display to a port on the left, and the other to a port on the right.
