Chapter 4 Settings — [PROJECTOR SETUP] menuENGLISH - 99[BRIGHTNESS CONTROL]The projector is equipped with a brightness sensor to measure brightness and color of the light source, andcorrects brightness and white balance of the projected image according to the changes in brightness and color ofthe light source.By using this function while structuring the multi-display by combining the projected images from multipleprojectors, the change in the brightness and white balance for the whole multi-display can be reduced or holddown the difference of the brightness and white balance to maintain uniformity, caused by the aging of the lightsource.Setting [BRIGHTNESS CONTROL GAIN]Adjust the brightness when displaying multiple images using multiple projectors.1) Press as to select [BRIGHTNESS CONTROL].2) Press the button.f The [BRIGHTNESS CONTROL] screen is displayed.3) Press as to select [BRIGHTNESS CONTROL GAIN].4) Press qw to adjust.Operation Adjustment Range of adjustmentBrightness Runtime (estimate)Press w. The screen becomes brighter. Maximum correction willdecrease. 20 % - 100 %Press q. The screen becomes darker. Maximum correction willincrease.Notef When using only one projector, the value obtained by subtracting the value of the [BRIGHTNESS CONTROL GAIN] from 100 % is themaximum amount of brightness correction. Brightness cannot be corrected through brightness control since the maximum amount ofcorrection becomes 0 % when [BRIGHTNESS CONTROL GAIN] is at 100 %.f The luminance will not stabilize for eight minutes after turning on the light source. Perform the adjustment after at least eight minutes haveelapsed after starting the projection.f The adjustment result of [BRIGHTNESS CONTROL GAIN] is reflected in all of the video signal, internal test patterns, and on-screen menu.f The [BRIGHTNESS CONTROL GAIN] setting is valid even when [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP] is set to[OFF].Setting [BRIGHTNESS CONTROL SETUP]Set the operation of the brightness control function.1) Press as to select [BRIGHTNESS CONTROL].2) Press the button.f The [BRIGHTNESS CONTROL] screen is displayed.3) Press as to select [BRIGHTNESS CONTROL SETUP].4) Press the button.f The [BRIGHTNESS CONTROL SETUP] screen is displayed.5) Press as to select [CONSTANT MODE].6) Press qw to switch the item.f The items will switch each time you press the button.[OFF] Does not correct the brightness of the screen by the brightness sensor.[AUTO]Corrects the brightness of the screen by the brightness sensor.When the brightness of light source or white balance changes, the brightness of the projected imageis automatically corrected.[PC] Synchronizes nine or more projectors using a computer and the dedicated software “Multi Monitoring& Control Software”*1 .*1 “Multi Monitoring & Control Software” is included in the supplied CD-ROM.f When [PC] is selected, proceed to Step 9).
