One of the biggest flaws of the Windows operating system becomes apparent in multi-user systems. Neither Windows XP nor Windows Vista offer individual screen resolutions for their user accounts. This means that a change to the screen resolution has global impact in the operating system. Each user account will experience the same display screen resolution.
Carroll is a small software program that offers a solution to this problem. The software is installed for all users allowing each to set their own screen resolution in the operating system. The computer program will display a list of available screen resolutions to the user upon startup. Selecting a screen resolution and clicking on the link “Change screen resolution and restore with every logon” will assign that screen resolution to the user. This will also be the screen resolution of all other users unless they specify a different screen resolution in the program.

This can be easily done as Carroll is installed for all users. Carroll needs to be autostarted with Windows if a custom screen resolution has been specified by a user. It will basically switch to the custom screen resolution upon startup.
