[Brightness Control] - Panasonic PT-DZ780 Operating Instructions Manual

[BRIGHTNESS CONTROL]

The projector is equipped with a luminance sensor to measure brightness and functions to correct screen
brightness resulting from changes in lamp brightness.
By using this function, it is possible to reduce changes in overall brightness of the multiple screens due to lamp
degradation and suppress variation in brightness to preserve uniformity when constructing multiple screens using
multiple projectors.

Note
f When using only one projector, the value obtained by subtracting the value of the [BRIGHTNESS CONTROL GAIN] from 100 % is the
maximum amount of brightness correction. Brightness cannot be corrected through brightness control since the maximum amount of
correction becomes 0 % when [BRIGHTNESS CONTROL GAIN] is at 100 %.
f Luminance will be unsteady for eight minutes after a lamp is turned on. Make adjustments at least eight minutes after starting projection.
f The result of [BRIGHTNESS CONTROL GAIN] adjustments is reflected on all video signals, internal test patterns, and on-screen menus.
