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: This is cropping, not electronic keystone adjustment. In Figure 2-14, cropping simply

corrects a display that overlaps the available screen.

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 1 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 1 of the cropping “bow” points

between 2 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

2-15). 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.
