Free resolution changer software for windows

Resolution Changer is a command line software that will change your desktop width, height, color depth, and refresh rate temporarily or permanently (via command line switches).
You can have ResChange run another application in a specific display resolution and return to the previous resolution when the application finishes. The command lines switches let you alter only certain dimensions and choose the best refresh rate (or a specific one).
Running reschange.exe without any switches displays usage information.
If you have an application that requires certain display settings (e.g., many childrens
programs require 640x480x256 colors), you
can modify that programs shortcut to something like this:
reschange.exe -width=640 -height=480 -depth=8 -refresh=72 "c:Program FilesHasbroFreddi.exe"
This shortcut will change to VGA resolution, run freddi.exe, and then restore the original display settings when freddi.exe stops running. If you dont specify a program, it will just change the settings for you (and not restore them).
The "8" represents an 8-bit color depth or 256 colors. "4" is 16 colors; "16" for 16-bit; "24" for 24-bit; "32" for 32-bit.
If you dont specify a parameter, the program uses the current setting for that value--except for the refresh rate; if you dont specify a refresh rate, the program will select the best refresh rate available.
Normally, ResChange 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 unsupported video mode. Please be aware that you can damage your video card or monitor by using an unsupported mode. 12noon assumes no responsibility or liability for your use of ResChange.
There is also a console edition that you can use from a batch file or script.
