SetRes

SetRes is a lightweight command line utility that enables you to modify the screen resolution, the color depth and the refresh frequency rate. Although these operations can be manually performed from the Control Panel, this application provides you with an alternative, convenient method.
The application only runs in the command console, but it features a simple syntax, which makes it suitable for beginner and experienced users alike. Its main window displays the command syntax, as well as usage examples, to help you understand how it works.
SetRes can only control a single display, but a multiple monitor version is also provided, enabling you to easily change the resolution and working parameters of multiple monitors simultaneously.
Both the horizontal and the vertical size of the screen can be configured, by entering the number of pixels for each of these two parameters. The minimum resolution can be set to 640X480. Note that SetRes does not check your display capabilities, since unsupported resolution settings should be automatically rejected by the system.
If you want to modify the screen resolution even more easier, you can create a shortcut for SetRes.EXE and enter the desired height and width values in the 'Target' field of the 'Properties' window. Double-clicking on the shortcut automatically changes the resolution, without having to deal with the command line options.
In addition to this, the bit color depth (which can be 8, 16, 24 or 32) and the refresh frequency (in this case, you have to enter a value in Hertz) can also be customized.
Although it is just a console application, SetRes provides you with a faster way of changing the monitor resolution, the refresh rate and the color depth of single-display systems.
