The resolution of mbp 1440x900 is too small, and 1680x1050 is too large, so I want to set a resolution of 1600x1000.
Run this sh file to manually set the required resolution and turn on hidpi mode.
Restart the system after running, you can see the resolution you added when you modify the zoom in the system preferences.
The backup code prevents GitHub from hanging. . .
