Adjusting the Brightness

You can adjust the brightness of your projector's light source.
  1. Turn on the projector and switch to the image source you want to use.
  2. Press the Menu button.
  3. Select the Settings menu and press Enter.

  4. Select the Brightness Settings setting and press Enter.

  5. Select the Light Source Mode setting and press Enter.
  6. Select one of the following options:
    • Normal: Sets brightness to maximum level (ideal for conference rooms, auditoriums, and lecture halls)
    • Quiet: Sets brightness to 70% and reduces fan noise (ideal for libraries, theaters, museums, and art galleries)
    • Extended: Sets brightness to 70% and extends the life expectancy of the light source (ideal for darker environments with ambient light, such as museums and art galleries, where a reduced maintenance cycle is desired)
    • Custom: Allows you to select a custom brightness level between 30 to 100%
  7. If you selected Custom, select Brightness Level from the Brightness Settings screen and use the left and right arrow buttons to select the brightness. To maintain consistent brightness, turn on the Constant Brightness setting.
    Note: If you turn on Constant Brightness, you cannot change the Light Source Mode and Brightness Level settings. If you turn off Constant Brightness, the Brightness Level setting changes according to the status of the light source.
  8. Press Menu or Esc to exit the menus.
Note: If you use the projector continuously for more than 24 hours, or regularly turn it off by shutting off the power outlet, schedule periodic Light Source Calibration events from the Extended menu. Otherwise, the Constant Brightness setting may not work properly.
