Figure 3.20. Screen Presentation Coordinates
NOTE:
Presently only a rectangular area can be defined, as shown above. A
trapezoidal adjustment or “electronic keystone” with sloped sides is not possible.
CROPPING NOTES:
Cropping is the
digital equivalent of filing aperture
plates in a film projector to perfect the
image “square-ness”. For example, if
the bottom of the image appears
slightly wider than the top, activate the
bottom left or right cropping point in
the
Screen menu and change the
coordinates to crop or “bring in” the
corner(s) of the image slightly—either
enter the specific coordinates, or adjust
with slidebars. Note that this is
cropping , not electronic keystone
adjustment. In Figure 3.21, cropping
simply corrects a display that overlaps
the available screen.
In most cases, cropping assumes that
the entire projector display area is in
use, thus the coordinates initially
define pixel locations on the
projector’s 2048 x 1080 display area.
Images that are significantly smaller in
format may actually lie beyond the
range of one or more cropping
adjustments, thus you will not see evidence of cropping on the edges.
To correct a “bowed” edge so that it appears straight in the display, activate one of
the cropping “bow” points between two corner points and adjust the slidebar or enter
the specific x or y value desired.
LETTERBOX NOTES:
Use letterbox for virtually all normal operation. It ensures that all
incoming data will be displayed within your defined presentation area, and nothing
will be discarded. If desired, any “black bars” (unused pixels) could then be cropped
off using the cropping control. Although disabling the letterbox control also fills the
defined presentation area, any extra data beyond this area—whether top-and-bottom
or left-and- right—will be discarded.
