Second external display not detected

sue3201 · 12-04-2023, 02:09 PM

I have two workstations set up with two external monitors having the same problem of only detecting one monitor. Both Macbooks - one M1 and one M2 - both latest Ventura OS. Both using UtechSmart docking station. The M2 workstation was working fine for months -- both monitors showing with no problems. All of a sudden, just one shows now. Have plugged/unplugged, switched hdmi ports, restarted macbook - can't get it to work. If I unplug one monitor, the other will show, so hardware works fine. For the M1 laptop (which is a new workstation I'm setting up), I'm having the same trouble from the start. Displaylink installed properly on both. Has anyone had similar issues?
