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.
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).
