Apple packed the biggest display it’s ever made onto the iPhone 6 Plus, and while its 1920×1080 resolution is great for streaming 1080p videos, it turns out that Apple also secretly added 4K video support without telling anyone.
The iPad Air 2, iPhone 6 and iPhone 6 Plus all support 4K video playback out of the box, thanks to the new A8 processor added this year. Apple doesn’t list 4K video playback as one of the A8 chips features, but the discovery was made by the developers behind WALTR, who posted proof of 4K video playback on the iPhone 6 this weekend.
