Resolution Changer is a neat software for Windows that can change the screen resolution temporarily or permanently. The author created the application at first for his children who were playing around with software that required a resolution of 640x480 and he did not want to change the resolution manually whenever they wanted to run their application.
The software has grown since then and some interesting features have been added to it. Resolution Changer can now change the desktop height, width, color depth and refresh rate on single or multi-monitor systems temporarily or permanently via the command line.
There are two main applications for this software. The first is if the monitor is always starting in the wrong resolution. This can happen with LCD TVs that the computer is connected to for instance. Just run Resolution Changer at startup to force the right screen resolution.
The second is applications that require a specific screen resolution. The temporary switch could be used to change the screen resolution before the application starts and turn it off once it is closed. The game toy.exe could be run in 640x480 using the following command:
reschange.exe -width=640 -height=480 "c:\toy.exe"
Additional switches are -depth=x -refresh=y which set the color and the refresh rate of the monitor while running the application. Monitors in multi-monitor systems are controlled with the -monitor="name" switch. The program is compatible to most Windows operating systems from Windows 95 to Windows Vista.
