Uploading A Gamma File - Christie Mirage M Series User Manual

smoothly overlapped creating a seamless image. Adjust white levels before adjusting black levels.
Christie recommends using blinders for fixed installations.
Similar to Edge Blending, Black Level Blending allows you to adjust the black level intensity of
multiple adjacent projected images to create one large seamless display.
Adjust white levels before adjusting black levels. The zones in the Black Level Blending (BLB) menu
correspond to the edge blend zones.
1. Start with two projectors. Select the black test pattern for both projectors from the Geometry
and Color submenu.
2. In the Black Level Blending submenu, enable black blending by selecting Standard from
the pull-down list for each projector.
3. Working with one projector at a time, use the center brightness slide bar to adjust the center
brightness (brightness of the non-blended region) so that the center intensity matches that of
the brightest blended region (the center of all images when blending a 2 x 2 display is the
target area).
4. You can choose which of the next four options, Top, Bottom, Left, and Right, to use depending
on which edge of the projector you are working with has been edge blended. The blend width
can be adjusted to line up properly but by default it corresponds to the edge blending setting
determined for that edge.
5. The brightness and black hues of the blended region can be adjusted in more detail in case fine-
tuning is needed (may be only necessary for blending a 2 x 2 projector display because of
blending differs for the sides and center).
The menu options vary depending on the edge blending parameters. When adjusting six or more
projectors, you need to ensure that the brightness of each target area is matched at closely as
possible.
