Duplicated monitors instead of separate extended displays
Multiple connected screens were duplicating the same image instead of working as separate displays. Support resolved it by disabling and then re-enabling the display drivers.
Killed once by someone from XL.net, on 2025-10-21.
Affects
Hardware

- display adapter/display drivers
What you see

- The display layout is behaving like mirrored/duplicated screens rather than extended displays.
Why it happens
Likely The display drivers needed to be reset; the ticket does not establish a deeper root cause.

You are in this case if:
- All attached monitors show the same desktop image.
