Mac Pro not remembering resolutions

Hey everyone,

I'm kind of new to the Mac life so please don't take this to be a stupid question if it is.

I started working at a company which uses a Mac Pro which pushes several external outputs to projectors. However, every time the computer is restarted, it looses the settings, changes the resolution down and mirrors all of the screens.

Essentially, it outputs from three DisplayPorts, one to the booth monitor, one to a triplehead which has a resolution of 3840x800 and another triplehead to 2560x800.

Every time the computer is rebooted, it reverts to several mirrored images at 1280x800.

Help? How can I keep the resolution and placement of screens over reboots?
