[PROJECTOR SETUP] menu
[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. Use the projector when using multiple projectors to display on multiple screens to reduce changes in overall brightness of the multiple screens due to lamp degradation and suppress variation in brightness to preserve uniformity.
1) Press ▲▼ to select [BRIGHTNESS
CONTROL].
2) Press the <ENTER> button.
zzThe [BRIGHTNESS CONTROL] screen is displayed.
3) Press ▲▼ to select an item.
■■To set [BRIGHTNESS CONTROLGAIN]Adjust brightness when using multiple projectors to display on multiple screens.

Note
zzWhen one projector is used, the maximum correction amount is the value obtained when the [BRIGHTNESS CONTROL GAIN] value is subtracted from 100%. When [BRIGHTNESS CONTROL GAIN] is 100%, the maximum correction amount is 0% and brightness cannot be corrected due to luminance controls.
zzLuminance will be unsteady for eight minutes after a lamp is turned on. Adjust after eight minutes have elapsed from the time that the power is switched on.
zz[BRIGHTNESS CONTROL GAIN] adjustments are reflected to all image signals, internal test patterns, and
zz[BRIGHTNESS CONTROL GAIN] is enabled even if [BRIGHTNESS CONTROL SETUP] is [OFF].

| Correction by luminance sensor is |
[GROUP A] | performed by connecting several |
projectors. | |
[GROUP B] | Use network functions to set up to four |
[GROUP C] | A to D groups within the same subnet. |
[GROUP D] | Up to eight projectors can be registered |
| and connected in each group. |
