Thinkpad P1. External monitor via Thunderbolt 3 dock station. Screen delay when the cover is closed.

2019-09-20, 11:01 AM

My problem is:


The external monitor (DELL 2715, 4K) is connected to ThinkPad P1 via Thunderbolt 3 dock station. Then the cover of notebook is closed, I move the app window by mouse, the window moves twitching. Then the cover is open, images on both screens, internal and external, are identical (clone mode), the window move very quick and smooth, like normal.

Also, if I see the video with closed cover, the video is twitching, but the cover is open, all the ok.

What is the solution of this problem? I need work on extarnal display with closed notebook cover.


Thank You!
