iPad SideCar Resolution Reset

Several threads are discussing the issue of scaled down iPad resolution.

An easy solution is to reset the resolution using https://github.com/univ-of-utah-marriott-library-apple/display_manager using the following commands in a terminal:

1. git clone https://github.com/univ-of-utah-marriott-library-apple/display_manager
2. cd display_manager
3. python3 -m venv .venv
4. source .venv/bin/activate
5. pip install pyobjc
6. python display_manager.py show # identify the display, mine was ext0
7. python display_manager.py res default ext0

After 7 everything is back to normal.
