If you have multiple streaming subscriptions and you want to access all content in one place, you'll want the best streaming device available, but what is that?
A streaming device is something, usually a box or a stick, that connects to your TV (usually via HDMI) and displays apps that are installed through Wi-Fi connectivity, once you're connected.
Visual Quality
In order to get the most out of your streaming device, you'll need a device (i.e. a TV/laptop etc) that can support the visual quality the streaming device offers. These days, the best streaming devices all support 4K viewing, although some support it better than others.
If you do have a TV, or another device that supports 4K viewing, you'll be pleased to hear that the Amazon Fire TV Stick, Roku Ultra, Apple TV and Google TV Streamer all offer 4K visuals. The Apple TV device offers the best picture with its 4K HDR ability, which means it offers 4K viewing, with improved contrast and brightness.
The Roku Ultra offers 4K UHD as a maximum resolution, whereas the Google TV Streamer offers a genuine 4K resolution and the Fire TV stick can play 4K HDR at 60FPS. All of this means you get high-quality visuals from each, but the Apple TV device is technically ahead, marginally, of the others.
