The Display Changer application was designed to be a small tool that 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. I originally wrote this application for my children because they had programs that required 640x480 with 256 colors or 800x600 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.

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).

There are Windows and Console editions for both 32-bit and 64-bit Windows. The Windows edition is best for creating shortcuts that quickly switch to the display configuration you want. The Console edition is best to use in a batch file or script.

NOTE:
Display Changer is free for personal and educational use

Warning
Normally, Display Changer will prevent you from using a mode that is not supported by your video card and monitor. You can use the -force switch to use an unlisted video mode. Please be aware that you can damage your video card or monitor by using an unsupported mode.
