This year’s major software releases from Apple bring a nice upgrade for watching YouTube videos on many of its devices. Follow along for how to watch 4K YouTube videos on iPhone, iPad, and Apple TV.

While iPhones and iPads don’t have 4K displays, they can show higher-quality video than the 1080p that they’ve been limited to with YouTube.

Funnily enough, even though Apple TV 4K has been out for three years, it’s just now gaining 4K YouTube support this year as well. You can watch YouTube in 4K on a Mac, but not with Safari for now. But we have seen the functionality arrive with macOS Big Sur for Netflix.

With iOS 14, iPadOS 14, and tvOS 14, Apple is offering 4K YouTube support.

Note: iOS/iPadOS/tvOS 14 are available as free public betas as well as developer betas. Read more here on how to install them. Keep in mind it’s not a good idea to run beta software on a primary device as performance issues, bugs, and more are worked out.

iOS 14: How to watch 4K YouTube videos on iPhone and iPad

  1. Open the YouTube app on your iPhone or iPad (4K not available with YouTube in Safari in iOS 14)
  2. Start playing a video and tap the screen, choose the vertical three-dot “More” icon in the top-right corner
  3. Tap Quality
  4. To watch in 4K, pick 2160p when available

Not all devices that can run iOS 14 get 4K YouTube support (at least at the moment). For example, with iOS 14 on an iPhone X, we didn’t see the functionality (we’ve also heard from a reader that doesn’t see the option with an iPhone XS).

On Apple TV

Note: Apple has announced 4K support is coming to YouTube on Apple TV at some point with tvOS 14. In the meantime, you can AirPlay 4K videos from YouTube on iPhone or iPad to Apple TV as a workaround.

  1. Open the YouTube app
  2. Start watching a video
  3. Press the touchpad on the Apple TV remote
  4. Select the vertical three-dot “More” icon
  5. Choose “Quality” and pick 2160p when available

Here’s how the steps look on iPad (same steps on iPhone):

How to AirPlay 4K YouTube videos to Apple TV

Before long you’ll be able to watch YouTube in 4K directly with the Apple TV YouTube app, but until then…

  1. In the YouTube app on iPhone or iPad running iOS 14, tap the screen of a playing video
  2. Tap the cast icon (rectangle with wifi symbol in the left corner)
  3. Choose AirPlay & Bluetooth devices
  4. Tap your Apple TV
  5. Alternatively, you can screen mirror your iPhone or iPad from Control Center (pull down from the top right corner on devices without a home button/pull up from the bottom of the screen on devices with a home button)
