Options NATIVE 5. Using On-Screen Menu Function The projector displays the current image in its true resolution when the incoming computer signal has a lower or higher resolution than the projector's native resolution. (→ page 2) When the incoming computer signal has a higher resolution than the projector's native resolution, the center of an image will be displayed. LETTER BOX The image of a letterbox signal (16:9) is stretched equally in the horizontal and vertical directions to fit the screen. WIDE SCREEN The image of a squeeze signal(16:9) is stretched left and right in 16:9. ZOOM The image of a squeeze signal (16:9) is stretched left and right in 4:3. Parts of the displayed image are cropped at the left and right edges and therefore not visible. FULL Project to full screen size. TIP: • Image position can be adjusted vertically using [POSITION] when the [16:9], [15:9], or [16:10] aspect ratios are selected. • The term "letterbox" refers to a more landscape-oriented image when compared to a 4:3 image, which is the standard aspect ratio for a vide source. The letterbox signal has aspect ratios with the vista size "1.85:1" or cinema scope size "2.35:1" for movie film. • The term "squeeze" refers to the compressed image of which aspect ratio is converted from 16:9 to 4:3. [INPUT RESOLUTION] The resolution is assigned automatically when the resolution of the input signal from the computer video input terminal or BNC video input terminal (analog RGB) cannot be distinguished. 81
