Most analog TV and computers are in 4:3 ratio, which is the default for this projector, and digital TV and DVDs are usually in 16:9 ratio.

Press / to select an aspect ratio to suit the format of the video signal and your display requirements. About the aspect ratio In the pictures below, the black portions are inactive areas and the white portions are active areas. OSD menus can be displayed on those unused black areas. 1.
