PRESENTATION NOTES
Presentation points define what region of the projector's available display area respond to incoming data. By
default, the projector uses its complete display area, scaling the incoming data as necessary. If for some reason
you want to limit the display area, enter the desired upper left and lower right presentation coordinates (or
adjust the up and down arrows for the x and y coordinates). You can define a smaller rectangular area in which
the left and right top corners will always share the same y coordinate and the top and bottom left corners will
share the same x coordinate. Thus upper right and lower left coordinates are not available to define the area.
Incoming data then automatically resizes to fill the reduced rectangular area defined by the new coordinates
and any display pixels outside of this area remain off (black).
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, select the
bottom left or right cropping point and change the coordinates to
crop or bring in the corner(s) of the image slightly. Either enter the
specific coordinates or adjust using the up and down arrows.
NOTE: This is cropping, not electronic keystone adjustment. 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 up and down arrows or enter the specific x or y
value.
LETTER BOX NOTES
Letter boxing ensures that all image data is
displayed and its aspect ratio is maintained.
Use letterbox for virtually all normal
operation. It ensures that all incoming data
displays within your defined presentation
area and nothing is 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. NOTE: Check Letter Box for all cinema presentations.
