Today Apple will present Apple TV the fifth generation with support for 4K, Dolby Vision, HDR10 and more. It will be pre-installed with a new standard screensaver Apple in 4K quality.
Jeff Benjamin found this screensaver in the latest version of tvOS 11. The HDR version of the video below didn't even work up to YouTube, it's so high quality.
Looks amazing, doesn't it?
The new default screensaver exists in regular and HDR 4K. The usual version was encoded with H.265 / HEVC in UHD 3840×2160 resolution.
To enjoy the screensaver to its fullest, watch videos in 4K (2160p) quality.
4K YouTube video playback doesn't work in Safari, so you'll need to use Chrome. In addition, to watch videos in such high quality, you need a fast Internet connection.
