I have no idea what occurred.. used monitor/laptop until 10PM last night. Worked this AM fine at 830 AM. Unplugged laptop to run to meeting, came back at 10:45 and it no longer works with 2nd display. Got it a couple times up there and then it disappeared... WTH.
Macbook Air M1 MacOS Ventura Just Stopped Working with Second Display (Nice LG Monitor) after working last night/this am
Hi there,
You might have better luck asking this question over in Apple Support Communities run by Apple Support.
Of course you tried to reboot the Mac ?
Have you the opportunity to test
- with another connection cable
- the LG Display on another Mac
- the Mac with another external display ?
May be in an Apple Store if there's one close to you.
PS: not sure WebKit is the most appropriate tag.
