What to do if the BenQ Interactive flat panel remote control does not work?
- N
  Nicole BurnsAug 10, 2025
  If the BenQ Interactive flat panel's remote control isn't working, several factors could be the cause. First, ensure the batteries are correctly oriented and not dead. Second, make sure you are within the appropriate range and angle from the display, and that the remote is pointed directly at the sensor window. Third, check for any obstructions between the remote and the sensor. Strong fluorescent lighting or direct sunlight on the sensor can also interfere, as can nearby devices transmitting infrared signals. Try turning off the infrared function on these devices.

  If the computer input image looks strange on your BenQ Interactive flat panel, it might be due to an unsupported output resolution. Try selecting a supported resolution. You can also use the Auto Tune function, which optimizes the display of the computer image automatically. If Auto Tune doesn't give satisfactory results, manually adjust the image using the Clock, Phase, Horizontal Position, and Vertical Position functions.
