A simple delphi tray application I wrote to allow switching between various resolutions on the machines at college, which were always locked to a ridiculously low resolution and refresh rate by the IT department.
It allows for rapid switching of resolutions by keeping a list of 3 resolutions in the right-click menu, which can be configured by the user and features the usual 15 second confirmation dialog to ensure the user doesn’t get inadvertantly stuck in an unusuable resolution.
