Description:

Installed with display drivers for NVIDIA based graphics cards since late 2002, this entry allows the System Tray icon to be displayed - which gives access to (amongst others) the display settings (such as Antialiasing, Rotation and Colour) and the Desktop Manager (nView). If you don't change display settings very often then this is not required and settings can be changed manually via display properties. No tray icon option is available in Vista. May be required for some 3D applications to recognize your card correctly - such as the game "Everquest"
