I've changed my resolution to a setting my screen can't display, and I can't change it back.

To run your game in a different resolution, you can add "-w -h " to the command line used when your game starts. Right-click on the game in your "Games" list, select "Properties", and select "Launch Options" to enter command line parameters.

For example: -w 1024 -h 768

To run your game using a different video mode, you can add "-soft" to start in Software mode, "-gl" to start in OpenGL mode, or "-d3d" to start in Direct3D mode.

Once your game is running successfully, you can remove these settings.
