Hello! Your Lenovo Thinkpad L15 (12th gen i5) is working well with a USB C dock in the office, but it doesn’t connect via HDMI at home. The external display appears but stays black, then disappears after about 15 seconds, and then it shows no external display again. You’ve tried updating drivers and a clean install, but the issue persists.

No, we didn't try another HDMI cable before checking the cable itself.

I'm working on the cable with an older laptop and everything is functioning properly.

Ensure the monitor's refresh rate is recognized accurately. I faced similar problems before and resolved them with a DP to HDMI adapter cable. It seems certain HDMI ports can be more sensitive than others.
