Hi guys - hoping someone here can help me!

I'm after a piece of (free) software that can control display settings?? What I'd really like to be able to do is create "profiles" that can be selected (maybe with a keyboard shortcut??) to change the resolution of attached monitors.

The situation is this:

A (very important) user has three screens attached to the machine - onboard, external, and projector.

When the projector is turned on, the PC defaults to sending it a 1280x800 res which the projector doesn't support (blurry etc). We can change the resolutions okay, but this has to be done every time and our (very important) user isn't happy with this solution.

Does anyone know of a bit of freeware that we can use to create a profile for when he has the projector in use, and one for when he doesn't so that the resolutions are as we need them??
