Sony has released an update for its PlayStation 4 Pro, bringing support for 4K video playback to the Media Player app on the console. The PS4 Pro already supported 4K video through streaming apps such as Netflix and YouTube, but the console can now play users' own Ultra HD videos too.
The update will enable the app to play videos stored in mp4 format on a USB stick or home server. "Your home server will appear as a media option in the Player automatically," Sony said, "so finding your media is simple and quick." However, it pointed out that "USB storage that’s already been formatted as extended storage for your PS4 can only be used to save games and apps – it can’t be used to save and play the videos."
The update also brings new support for 4K virtual reality content through PlayStation VR, as Sony explained:
For those of you that own a PlayStation VR system in addition to PS4 Pro, Media Player will also update to support playback of 4K VR video content. PS VR’s display resolution is 1920 x RGB x 1080, therefore 4K VR videos will be displayed in a higher image quality compared to HD VR videos. Capture stunning 360 degree 4K footage, and then immerse yourself in that footage in VR at home – just as if you’re right back in the scene you shot.
Of course, one omission that a software update can't address is the PS4 Pro's lack of 4K Blu-ray support - that's down to the fact that Sony didn't include a 4K Blu-ray drive in the console. Microsoft's Xbox One S, on the other hand, does have a 4K drive, as well as supporting other Ultra HD content.
