maybe i misunderstand qres, but i want to do this through GPO for the following reason.
We have students and users who can change the resolution on a monitor. We want at startup and logout to shift a monitor back to a "default" res (say 1024x768). we would like to be able to also set this at the OU level so it can be 1440x900 for 19'' wide, 1650x1050, etc. We want it to be automatic, and we want to also have the nice effect of the laptop using the whole monitor
we dont want this for a program reason, we want to set it so one person doesnt leave it at 800x600, and then the next user complains
edit: i should also mention we are using Windows 7 x64 Enterprise
