Frequently Asked Questions

BenQ projector No Signal but laptop screen is working fine?

The laptop is outputting only to its own screen. Press Win + P on Windows and select Duplicate or Extend to enable output to the BenQ projector as well.

BenQ projector No Signal after connecting a game console?

Check the console video output settings. PlayStation and Xbox must have their video output set to HDMI. Also verify the HDMI cable is plugged into the ARC or output port on the console, not an input port.

BenQ projector alternates between No Signal and image every few seconds?

An intermittent signal is almost always caused by a loose or damaged HDMI cable. Replace the HDMI cable and ensure both connectors click firmly into place.
