Section 3: Operation
In most cases, cropping assumes 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; therefore, evidence of
cropping on the edges will not be seen.
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.
• Letterbox: Letterboxing ensures all image data is displayed and
its aspect ratio is maintained. Use letterbox for virtually all
normal operation. It ensures all incoming data is displayed
within the defined presentation area and nothing will be
discarded (Figure 3-38). If desired, any "black bars" (unused
pixels) could then be cropped 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
Letterbox for all cinema presentations.
• Screen: Select a screen file name from the drop-down list to modify settings or create a new screen file with
a different name.
• Lens Factor: Define the anamorphic needed to stretch an image horizontally. Leave at 1 (default) if no lens
is needed.
• Save: Save current settings as a Screen file, which can be accessed through the Channel: Page 1 menu.
IMPORTANT! To save settings to a new screen file, edit the screen file name before saving. Otherwise, the
settings of the loaded screen file will be overwritten. Restore will not cancel a Save.
• Restore: Cancel new (unsaved) screen settings and return to previously saved settings.
