Prior to this, Google Play’s 4K movies were only limited to a handful of devices and TVs, but with the update to NVIDIA Shield TV, you’ll be able to enjoy 4K movies regardless of what TV you’re watching it from, as long as the NVIDIA Shield TV is connected to it. In addition to supporting 4K for Google Play, the update will also enable 4K support for Google Cast.
This means that you can push 4K content from devices like your smartphone or tablet to the Shield TV and enjoy it there. Prior to this, the device also supported (and still does) Amazon Video in 4K and also 4K HDR content. It also supports 4K streaming from the likes of YouTube, Netflix, Google Photos, Vudu, Plex, Kodi, and Vimeo, but this update should now make the device more appealing.
