LCD died. Is there a key cmd to mirror displays for Ventura?
Description:
A 2019 16" (A2141) shows rainbow-colored vertical lines. On the first two or three occasions, the display was normal until the lid was opened more than about half-way, but now only the vertical lines are shown.
(This is my dad's laptop. He thinks he's on Ventura, but isn't positive.)
Steps Taken:
1. I reset the NVRAM and the SMC.
2. I was able to connect an external monitor using HDMI which shows wallpaper and "Desktop 2", and I can move the mouse pointer onto the external screen.
3. I tried Cmd-F1 to mirror the display. That didn't work.
4. I tried "Hey, Siri, mirror my display." That didn't work, either.
Questions:
1. Is there a keyboard shortcut to mirror displays on a touchbar laptop running Ventura?
2. If no, is there another way to mirror displays without seeing the screen? (e.g. cmd-space t-e-r-m defaults write blah blah)
3. LCD shows only rainbow-colored vertical lines, but computer does boot. Can I be fairly certain that replacing the display assembly is the fix?
Thanks in advance.
