Despite all the 4K material NVIDIA's Shield TV can handle, there have still been a few gaps: you couldn't play Google Play Movies & TV content in 4K, for instance, and you definitely couldn't Google Cast the 4K videos of your choice. Thankfully, NVIDIA is plugging those two holes today. An update lets all Shield TV boxes play both the content you Cast and Google Play titles in the ultra-sharp resolution, so you don't have to be quite so picky when looking for material beyond 1080p.
