This resets the projector’s tracking and sync settings. ■If further adjustment is needed, you can fine-tune the Tracking and Sync settings manually using the Image menu as described on page 49. 1. Fill the screen with an image containing fine detail when making these adjustments. For example, in Windows you can select a pattern to appear as your desktop background.
