NVIDIA has just added a feature to its Shield device that might just pull in a drove of new consumers - 1080p streaming. You can now use NVIDIA's GameStream console mode to stream your PC games to your TV, all at the glorious 1080p res.
Although the words 'streaming' are used, there's no wireless trickery here, unfortunately. Cables are still used, as you'll need an Ethernet cable for 1080p, and you'll also require the Shield's microUSB port, too. If you want to check out the latest update, it should be getting pushed to your Shield right now, or very soon.
