Apple TV might get 4K video streaming, but it'll still lag behind

Big things could be coming to the Apple TV.

Last revamped in late 2015 with beefier hardware, a refreshed tvOS interface and the Siri Remote, Apple's set-top box has basically languished as competing set-top boxes like the Amazon Fire TV, Roku Ultra and the new NVIDIA Shield TV run circles around it.

That could soon change. Apple is reportedly testing a new Apple TV capable of streaming 4K video with "more vivid colors (sounds like HDR), according to Bloomberg. The current Apple TV only outputs at 1080p full HD, which is fine, but it's no 4K.
