I think this is a known issue. Hopefully they can push am update to improve or get rid of the delay


Thanks for bringing this issue to our attention.

May I know if you have tried a different HDMI cable or connected with another device via HDMI to see the same delay? It’s the nature for the potential delay when connecting to other devices. But per most users feedback, this shouldn’t affect your projecting experience.

If you have concerns, please contact our customer support team at with a short video to display the issue, we will try best to assist further. Thank you!
