External 5k (LG 49WL95C) monitor problems after Ventura update
I used a lot of time to fix my monitor. To avoid you doing the same. This is how I fixed it temporary.
- Disconnect external monitor
- Run the command in the terminal: sudo sleep 20; sudo kill -9 $(pgrep WindowServer)
- Enter the admin user password and press enter
- Connect external monitor before 20 seconds had passed
- After 20 seconds, you will need to log in to macOS again, but this time your monitor should work
Happy Christmas
