Change resolution temporarily or permanently with command line switches
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 dc.exe without any switches displays usage information.
