Change Display Resolutions Automatically

Did you ever run an application that was designed for a specific resolution on your new shiny 1920x1200 monitor only to find out that it was almost impossible to work with it in that resolution? I'm not only talking about old DOS games here but also about presentations for instance or applications that have been developed in house. Basically any kind of software that goes full screen automatically can cause a problem in these situations.

Res-o-matic comes to the rescue. The application creates program shortcuts that force the desktop to a specific screen resolution, refresh rate and color depth. The minimum screen resolution available is 640x480 while the maximum probably depends on your monitor, mine was set to 1280x1024. Colors Depth can be set to 8,16 or 32 bit and the refresh rate again depends on the monitor and can be completely ignored if you have  a LCD monitor.

A shortcut will be created in the end which - when pressed - will change the display resolution accordingly and launch the application afterwards. Exiting the application changes the display resolution back to the original one.

Res-o-matic is a tiny 9 Kilobyte tool that comes in very handy, it's probably the easiest way to change the screen resolution automatically at every application start.

The program is fully compatible with all recent versions of the Microsoft Windows operating system. I have tested it under a 64-bit version of Windows 7 Professional and the program did exactly what it was supposed to do. Executing the shortcut displays an UAC prompt which you have to accept. The screen resolution changes then automatically to the selected, and back to the default resolution once you close the application again.

The program displays only supported resolutions so that you should not run into issues here. The program is as lightweight as it can get and excellent in terms of functionality.

    I have a wide screen monitor that does not work well with Photoshop®. Squares and perfect circles are distorted in the horizontal state. Photoshop® is set up for 1024 x 768 resolution and does not work well with anything else.
    Res-o-matic and a few minor adjustments to Photoshop® now gives me perfect resolution at 1280 x 800.
    Thank-you very much for producing this little utility.
