A simple toolbar and menu that pops up from the system tray provides configuration and fast access to your favorite display settings, incremental enlargement and reduction of desktop size, comprehensive color calibration controls with gamma hotheys, the ability to associate specific applications with custom display settings, graphics system diagnostics, flexible font controls, extensive hotkey and screen saver support, a database of over 1000 monitors, and on-the-fly color depth, resolution and refresh rate switching. Additionally, the PowerStrip includes direct hardware support for many chips, permitting an unprecedented degree of control over your display sub-system, particularly under Windows NT."
