It is fine sync to 4K resolution. Any suggest for my case ? Please adivse.
Apple TV 4K
Are there any devices connected in between the Apple TV 4K and the projector (e.g. AV receiver, extender, switch)? Are they also 4K HDR/HDMI 2.0/HDCP 2.2 compliant?
Are you using HDMI 2.0/“Premium High Speed”/18 Gbps HDMI cables?
Have you tried resetting the video settings on Apple TV?
