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.
The projector displays the current image in its true resolution when the incoming signal has a
lower or higher resolution than the projector's native resolution. (→ page 182)
When the incoming signal has a higher resolution than the projector's native resolution, the center
of an image will be displayed.
