Fix 4: Use HDMI 2.0 Cable
If you’re still experiencing YouTube 4K videos not playing on Apple TV 4K, you have to check the HDMI cable version that you’re using on your Apple TV 4K. You might be watching your favorite content shows in Full HD on other streaming platforms, and this might have been left unchecked from your end. But to access and stream the videos in 4K resolution, you need to have an HDMI 2.0 cable which allows a higher bandwidth of 18Gbps and a peak resolution of 3840×2160p @60fps (4K@60fps).
