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. To edit the upper left coordinates, select the top left option button and then adjust the X/Y values
using either the sliders to increase/decrease the value or click the Launch Dialog button in the Presentation
X/Y boxes to launch the on-screen keyboard. (Figure 3-29). Using the sliders moves the projected display area
in real-time. You can define a smaller rectangular area in which the left and right top corners will always share
the same "y" coordinate (y = 175 in Figure 3-29), as will the left and right bottom corners (y = 951 in Figure
3-29). The top and bottom left corners will share the same "x" coordinate (x = 80 in Figure 3-29), as will the
top and bottom right corners (x = 1120 in Figure 3-29), thus top right and bottom 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).
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
bottom right option button and then adjust the X/Y coordinates using either the sliders to increase/decrease
the value or click the Launch Dialog button in the Cropping X/Y boxes to launch the on-screen keyboard.
The intent is to crop or "bring in" the corner(s) of the image slightly. NOTE: This is cropping, not electronic
keystoned 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.

Description
Cropping hides unwanted data, i.e. if the image appears keystoned. See Cropping Notes below.
To adjust the top, left cropping point, select the top left option button and then adjust the X/Y val-
ues using one of the two options:
• adjust the sliders to increase/decrease the value. Using the sliders moves the projected display
area in real-time.
• click the Launch Dialog button in the Cropping X/Y lists to enter a value using the on-screen
keyboard.
Repeat this action after clicking the top right; bottom left; and bottom right option buttons.
When the top middle, right middle, bottom middle, left middle option buttons are
selected, adjust the Curve value using either the slider or on-screen keyboard.
