Troubleshooting

Display Available Without Audio

• Projector is muted

• Device (PC, TV, etc.) muted.

• Dolby sound is not supported, exit to play again.

• Profile audio format is not supported by projector. E.g. Projector supports 1080P and 1080I video won’t play audio.

• VGA connection can only transmit analog signal of video not audio. External speaker is required when device is connected via VGA cable.

• Encryption applied on the videos or media player which holds the video. Try more videos to define this possibility.

• Exclude possibilities above, try another HDMI cable /external speaker, and a 2.0USB disk/ Micro SD card within 32G/USB hard disk within 1TB to play directly to see if both video audio available.
