This application can change your desktop width, height, color depth, and refresh rate temporarily or permanently (via command line switches). It also supports multi-monitor configurations. You can have Display Changer run another application in a specific display resolution and return to the previous resolution when the application finishes. DC can also re-arrange monitors in a multiple monitor configuration. The command line switches let you alter only certain dimensions and choose the best refresh rate (or a specific one). Running without any switches displays usage information.
