PRESENTATION NOTES:
Presentation points define what region of the projector's available display area responds to incoming data. By
default, the projector will use 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 with slidebars). You can define a smaller rectangular area in which the left and right top corners will
always share the same y-coordinate (as will the left and right bottom corners), and the top and bottom left
corners will share the same x-coordinate (as will the top and bottom right corners). Thus upper right and lower
left coordinates are not available to define the area. Incoming data will then automatically resize to fill the
reduced rectangular area defined by the new coordinates, and any display pixels outside of this area remain off
(black). NOTE: Presently only a rectangular area can be defined, as shown below. 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 squareness. 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 3-28, 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.
