Black Level Uplift
Black Level Uplift is used to compensate for the lack of pure black output from projectors, due to light leak-
ing to the projection screen. When projecting black , the hot area where the two images overlap project
twice the projectors’ black output levels.
The solution is to adjust the Black Level Uplift. First make sure that the units connected to the projectors are
outputting black. Then increase the Black Level Uplift (Top, Bottom, Left, Right) until the non-overlap area’s
brightness matches the overlap area.
