Frequently Asked Questions

BenQ projector powers on, lamp is lit, but the screen is totally dark?

Check whether the Blank function has been activated. Also ensure the source device is outputting video. If both are fine and the screen is still black, try a factory reset via the Settings menu.

BenQ projector shows blue screen instead of image — what does it mean?

A blue screen (not black) usually means the projector is on the correct input but the source device is not sending a signal. Wake the source device from sleep and check the cable.

BenQ projector image disappeared during presentation — how to restore quickly?

Press the Blank button on the remote — a single press usually restores the image immediately. If Blank is not the issue, check that the HDMI cable has not been knocked loose.
