Switching screen res on OS X

[Sarah Reichelt]

Hi All,

Several times people have asked how to change screen resolution
programmatically. I usually recommended the Terminal command "cscreen"
but it is no longer under development and it does not handle all
resolutions especially the "stretched" ones.

I have now found another option called SwitchResX
<http://www.switchres.info/html/SRX/About.html>. It is not free, but
it is a lot more powerful and as it is AppleScriptable, you can use it
in your scripts once it is installed.

Cheers,
Sarah
