Dear Abu Hamzah,

If you're using an Apple TV connected via HDMI, try the following:

1- Go to Settings → Video and Audio
2- Change the output resolution from 4K to 1080p
3- Temporarily turn off Match Dynamic Range and Match Frame Rate

Also, let me know which of the following best describes the issue:

p1- The projector doesn't appear as an AirPlay device.
p2- It connects, but the screen stays black.
p3- Audio plays, but there's no video.
p4 It disconnects after a few seconds.
p5 You receive an error message.

If you're not sure, or you'd like me to check your settings, upload photos of the Apple TV Video and Audio settings and the projector's AirPlay or display settings, and I'll tell you exactly what to change.
