BRIGHTNESS CONTROL

This projector has a built-in brightness sensor for measuring the lamp power and a function for correcting the screen brightness according to the change in lamp power.

With this function, you can reduce changes in brightness caused by aging of the lamps when multiple screens are projected using multiple projectors, or minimize any fluctuations in brightness.
