NVIDIA just underscored one of the advantages of having a high-powered streaming media hub: you can roll out new video features before anyone else. It's delivering an update to its Shield set-top box that introduces high dynamic range Netflix video on supporting TVs -- a first for a stand-alone device, NVIDIA claims. You can also watch YouTube videos at both 4K and 60 frames per second, while Vudu 4K support is equally new. And if you're an audio junkie, you'll be glad to know that Dolby Atmos' extra-immersive audio gets a direct pass-through when you're using apps like Vudu, MX Player and NVIDIA's own media gallery.
