SB-TB4 KVM - Apple Studio Display monitor not working


  • When switching from my Dell laptop to either a Mac-mini M1, or Macbook Air M2, the Apple Studio Display is not recognized but my 24 inch ASUS monitor starts up fine.

    When I switch back to the Dell laptop, both monitors appear and work great.  

    I have switched out numerous combinations of cables, which ports the monitors are plugged into all in a hope to get a different result.

    Has anyone else experienced this?  I'm trying to get this working so I can have less keyboards, monitors, etc on my desk, but I'm about to box it up and return it.



  • @glenramirez You might need a TB4 dock + KVM switch, see the comments here. Some Apple hardware only supports one external display otherwise.
