When I am customizing the image displays using the Extended menu, should I choose USB Display for the USB Type B setting or select ON for the Link21L setting?

• If you want to project images using a USB connection instead of a VGA connection, select USB Display for the USB Type B setting. If you are using a USB connection, and want to use the projector's remote control as a wireless mouse to monitor and control the projector from the computer, set Link21L to ON.
