Why does the light turn on and off by itself?

You might have activated the auto on/off function, which detects motion in a 23.6±3.9" cone-shaped area ahead.

Why doesn't my wireless controller work?

The controller is not faulty. When idle, the icons dim. To activate the controller, tap any function icon first (not the display panel). Then rotate the dial to adjust brightness/color temperature, or press another icon to use its function.

Why do I see glare on my screen when using ScreenBar Halo 2?

ScreenBar Halo 2's asymmetrical optics prevent screen glare. If you notice glare, the lamp may not be mounted correctly. Please ensure the clamp’s top is completely flat, not tilted. You can also rotate the lamp to adjust the angle for your monitor.

Is my monitor compatible with the ScreenBar Halo 2?

ScreenBar Halo 2 fits monitors 0.17–2.36" thick and 1000R–1800R curved screens. For more information, please contact BenQ.

Why does the power on/off button on the wireless controller keep blinking and fail to control the lamp?

The blinking means that the controller has lost its connection with the lamp. To restore the connection, please follow the tutorial video on this product page or the guide on BenQ’s website. For more help, contact our customer care via online chat.
