Apple just announced a new Apple TV that will stream video in ultra-sharp 4K resolution

Apple TV is going 4K.

Apple announced the Apple TV 4K on Tuesday during its annual September event from the new Steve Jobs Theater at its new Apple Park campus.

The new Apple TV 4K will be able to stream 4K - or UHD (ultra high definition) - resolution video, which is sharper than the full-HD 1080p resolution from previous Apple TV models.

The Apple TV 4K will also support HDR (high dynamic range) to produce better colors and contrast between light and dark areas of a scene.

Apple also announced that 4K movies and TV shows will be sold at the same price as their HD counterparts, and that movies that were bought in HD in the past will be automatically upgraded to 4K for free.

The new Apple TV 4K runs on the A10 X Fusion Chip, the same chip inside iPad Pro that's twice as fast as current Apple TV.

The new Apple TV 4K will be available to buy for $179. You can pre-order it starting on September 15 and it ships a week later.

This story will be updated as more is announced.
