Hello guys,
I have this strange problem with my new BenQ XL2411P. Sometimes I see this blinking gray rectangle on the top part of the screen. when I paused and analyzed it is always the same clean shape, always the same color, and always at the same place. Video: https://gfycat.com/pasticycowbird

  • It happens only with DP cable, HDMI and DVI are without issue. Already tried a different DP cable.
  • It's most likely a screen issue since recording software can't pick it up. With the screen, I tried a different power cable and the wall outlet.
  • I've noticed it mostly happens when the GPU changes clocks, but not always and not on every clock change, maybe only in like 1in50 cases or so.
  • I've already tried multiple GPU drivers, screen settings, changed PSU, and did a lot of research, but no one seems to have the same looking issue.

My setup:
BenQ XL2411P
Intel Core i7-6700K
MSI Z170A GAMING PRO - Intel Z170
Kingston HyperX Fury Black 16GB (2x8GB) DDR4 2133
MSI GeForce GTX 1660 SUPER VENTUS XS OC, 6GB GDDR6
Seasonic Focus Plus - 650W
