Want the highest quality Netflix and Amazon to feed your brand-new 4K HDR TV? Don't want to ditch your old AV receiver quite yet? Roku Ultra is the answer.

Unlike the Apple TV 4K, though, the Roku Ultra only features 4GB of internal storage, whereas the Apple TV 4K offers 64GB and 128GB of storage, depending on the model you purchase.

The latest version of Google's tiny streamer, dubbed Chromecast Ultra, can deliver 4K resolution streams from Netflix and others, complete with high dynamic range, for an affordable price.
