Frequently Asked Questions

Optoma projector shows power light on but completely black screen?

A powered-on projector with a fully black screen almost always means the Hide button was pressed. Try pressing Hide on the remote first before investigating further.

Optoma projector blue screen instead of black — source not detected?

A blue background screen means the projector is on the correct input but no signal is arriving. Check the cable, wake the source device from sleep, and confirm the output is enabled.

Optoma projector image disappeared mid-use and will not return?

Check the Hide button first. If that is not the cause, the HDMI handshake may have been interrupted — unplug and reconnect the HDMI cable to force a fresh handshake.
