Chromecast Ultra is the best Chromecast you can get
Chromecast — both the hardware and the protocol behind it — maybe is one of Google's most important products of the past few years. If you've ever watched a video on your phone and wished that you had an easy way to watch it on your TV, Chromecast is the answer. And, perhaps more important, it's a relatively inexpensive answer.
Chromecast Ultra is a simple device — an HDMI dongle. You plug it into your TV's HDMI port, and plug in the included power connector, set it up in the Google Home app, and you're done. You'll want to be sure to use the included power brick with the Chromecast Ultra , as 4K video needs a little more juice to keep all that data flowing.
Chromecast Ultra an inexpensive, long-term way to watch 4K video.
In addition to supporting 4K resolution, Chromecast Ultra also has support for HDR10 and Dolby Vision, the two competing standards of HDR video.
Chromecast Ultra also should be future-proofed for the foreseeable future. The 4K video standard isn't going to change anytime soon. So even if you don't yet have a 4K-compatible television, you should still spend a few extra dollars on Chromecast Ultra now for when you do get an upgraded TV.
Alternatives to Chromecast Ultra
Chromecast Ultra has a little brother — simply named Chromecast. It was refreshed in 2018 but still tops out at 1080p resolution. If you need a Chromecast but know that you won't be needing it with 4K video anytime soon, then this will be the Chromecast you want to get. (Say, for a secondary TV in a guest room.)
They work exactly the same way, it's just the end result that's different. Chromecast Ultra does 4K video with HDR, the "regular" Chromecast doesn't.
Runner-up
The Chromecast you need if you don't need 4K video.
It's the same easy-to use Chromecast as the Chromecast Ultra, just without 4K video, and with a lower price tag.
It's as simple as that. This Chromecast is the same as the Chromecast Ultra, only its video tops out at 1080p instead of 4K, and it's less expensive. If you know you won't be needing 4K video on a TV, then this is the Chromecast to get.
Also
This little Chromecast only does audio.
It does for audio what Chromecast Ultra does for video.
If you have a stereo receiver that's great but doesn't include any sort of connectivity to it, this is an inexpensive way to stream music.
Bottom line
