ChRes is a small tool for use from the command line. I wrote it when I was having problems with certain graphics card drivers not restoring the correct screen resolution after rebooting and switching between CRT and TV-out. You can add a link to it in your Autorun folder to always set a specific resolution after booting. The program is under active development and new versions will be released as new feature requests come in. The program can possibly damage your hardware when using invalid parameters, so use with care and at your own risk!
