Mouse will not move to the other external display under clamshell mode

[jonjal]

Hi, I'm having trouble using two external displays with DisplayLink-compatible device with my MAcBook Air M2 when it is in clamshell mode. It works fine, all three (2 external and 1 builtin) monitors work fine when the MacBook is open and not in clamshell mode.

Here's what's going on: when I close the MacBook to go into clamshell mode, my "focus" is set to the left monitor. The right monitor stays powered on and displays the screen, but does not move. Also, when I try to move my mouse to the right monitor, it will not let me, as if the only monitor available is the left one. While having this problem, the display tab in system settings is aware of the other (right) display. It feels like I'm using the MacBook in clamshell mode with one (the left) external display, while the right one is just a static screen.

Here's my setup:

• HW: MacBook Air M2 (13.6 inches, 16GB/512GB) + SW: macOS Sequoia 15.0
• HW: Belkin Connect Universal USB-C Triple Display Dock + SW: latest DisplayLink software (1.10.3)
• HW: 2x LG 32UP830 32-inch 4K monitors

Any help would be greatly appreciated, thanks!

It sounds like you need to change your display 'arrangement' in macOS. Your description suggests that your Mac thinks your left monitor is on the right when it is actually on the left, and vice-versa.

The 'Arrange' option is described by Apple here --> https://support.apple.com/guide/mac-...ac-mh40768/mac
