Display Changer changes the display resolution, runs a program, then restores the original settings. It can also change the resolution permanently and rearrange the monitors in a multiple-monitor setup. This is useful for games and home theater computers. I originally wrote this application for my children because they had programs that required 640×480 with 256 colors or 800×600 with 32-bit color or some other combination. I didn’t expect my (then) 4-year-old to be able to change Windows display settings, so I wrote this program to do it automatically.

Now, it does much more.

Display Changer changes your desktop width, height, color depth, and refresh rate (frequency) temporarily or permanently (via command line switches). Display Changer can run another application in a specific display resolution and return to the previous resolution when the application finishes. Command line switches let you alter only certain settings and choose the best refresh rate (or a specific one).
