I’ve got a Lenovo Thinkpad P15s with Win 11 and the latest bios/firmware/software. Connected via 2 x DP to two Dell P3222QE monitors. The monitor in the dock DP #2 flashes off/on intermittently. The problem will follow the port, not the monitor. I’ve also tried connecting the second monitor via HDMI and have the same issue. While probably not necessary, I’ve applied the specific monitor drivers.
I’ve got several of these installed, but on MacBook Pros. This is the first time I’m attempting this Lenovo setup.
After reading through several similar issues it appears these are examined on a case by case basis.
