After a couple of quiet years, Apple has finally made some much-needed upgrades to the Apple TV and released a brand new Apple TV 4K model that supports super-high resolutions and HDR streaming.

Despite this significant upgrade, though, the Apple TV has retained its minimalist design. There’s nothing about this unassuming black box that gives away its high resolution capabilities so we’re glad that iFixit, a site famed for its teardowns, has taken Apple’s latest streaming device apart to reveal just what’s going on in there.
