Read Known issues before testing.
Erase all known display configurations saved on the computer. There is a reg file for this in the extras folder.
Restart the computer after erasing the display configurations.
-
Try to run the program and see if it works when there are no known display configurations.
-
Switch between different display configurations and see if the program works.
- Do this while the computer is shut-down and while it is running.
-
Go into Windows 10/11 display settings and make some 'misconfigurations' such as incorrect resolution, changing the arrangement of the screens, or placing them in the wrong order.
-
Set the primary display to different displays and see if the program works and selects the left-most external screen as the primary display.
-
Try to run the program with only one screen connected - this should only adjust the resolution of the screen to the optimal resolution and exit.
-
Try to start the computer connected to multiple displays with the lid closed and run the program.
-
Try to "fuzz" the inputs to the program by entering invalid values and see if the program crashes.
