Udate to Montery mini m1 16gb external monitor

[paulv1958]

Just updated. Only 2 issues.
Partway through install my LG 4k screen displayed a blue box in the center of the screen with flashing lines for 2-3 minutes then Mini restared ( not from error) and all for rest of install. Screen size had to be reset.
Ethernet port disabled and wifi enabled by default. Reenabled ethernet & disabled wifi all good.

No other problens so far.

I had the exact same experience. Was really trippy. I’ve had OSX do weird visual stuff on updates before and knew to just wait it out. It was REALLY extreme visual though and I would be concerned others would try to reboot.

Same here with LG 4k too. Flashing horizontal blue boxes, various length, from right side of screen. Waited it out and all ok.
