When lid closes, with Dual monitor extended, one display no longer extends
I am at a conference. I have 2 monitors extended as follows:
- main screen (will be closed).
- When closed, displays remain on ✅
- Display 1:
- extends main
- Display 2:
- mirror of #1
However, when I close the lid, 1 of the extended screens just shows the wallpaper.
Please advise on how to keep them both on
