Steve,
Would Multires work for you?

We've used that on machines in our labs before.  You can set it to run
in the system start up script either by group policy, or the local group
policy of the machine (gpedit.msc).

Once the machine is rebooted the startup script with the command line
interface will set the screen and video mode to the proper mode.  This
allows for people to be able to change the screen resolutions, but
return to normal once they have been rebooted.

Subject: [MSUNAG] How do you keep an open PC working in a classroom?

   I have a Dell in a lecturn, which can be displayed on an overhead
projector.

   My problem is folks often don't know how to use it, and wind up
twiddling with things, messing the config of the machine up such that
others can't use it to project onto the screen.

   Now, part of the problem may well be hardware.  It's an older Dell
with an early ATI dual-head video card and I'm fairly sure that it
looses its little mind from time to time, and shuts the 2nd head off,
making for a merry time getting it back again.

   So,  in the  case of a machine thats physically out there, what
things do you do to make it "just work" for people?

Thanks!
