Everything you need to know about Roku in 4K

Roku revolutionized how we watch TV. With its wide range of devices to choose from, Roku made it so you don’t need a smart TV to watch your favorite streaming services. 

The Roku interface is popular and is used by smart TVs like Sharp and TCL. You can enjoy Roku in 4K with all of your apps that support it. Roku also offers its own brand of smart TV with Roku 4K TV. Along with 4K streaming, Roku TVs come with upscaling technology that improves your streaming quality. 

Roku’s devices range from affordable set-top-boxes to high-quality media players. If you want to watch shows and movies in 4K resolution, Roku has a device for you. Keep reading to discover what Roku devices stream 4K TV. 

What are the basics of Roku 4K? 

A 4K quality image packs in four times as many pixels as high definition (HD). The more pixels that are crammed into the screen, the greater the quality you’ll get. So, for example, most HD TVs come in standard 1080p resolution at 1080 x 1920 pixels. By comparison, 4K Ultra HD has 2160 x 3840 pixels. With it, there’s a wider spectrum of colors, while shadows are deeper and darker. 

As noted in the introduction, Roku is available in the form of smart TVs and media player devices. However, not every Roku device provides 4K quality. (But more on that below.) This means that any subscription service that you have, like Amazon Prime Video and Netflix, that supports 4K streaming is compatible with select Roku devices. 

But there are a few things you need to consider. First, your TV should have an HDMI 2.0 input for your Roku device to plug into. Second, you should test your internet speed to make sure it’s fast enough. On their website, Roku recommends around 25 Mbps to stream 4K ultra-high-definition (UHD) content. And, of course, make sure you have a 4K TV. 

Which Roku devices stream in 4K? 

Roku offers a few devices that’ll let you stream in crystal-clear 4K resolution. But first, let’s identify the ones that don’t offer 4K — Roku Express and Roku Express+. Below are the Roku devices that offer 4K quality streaming. 

Roku Premiere – $39.99

Roku Premiere is a simple and straight-forward device. The main feature of the set-top box is its ability to stream in up to 4K Ultra HD.

Roku Streaming Stick+ – $49.99

Roku Streaming Stick+ is a smaller, flash drive shaped device that’s inconspicuous. It also comes with a voice remote with TV controls. 

Roku Streaming Stick+ HE – $59.99

Roku Streaming Stick+ HE is essentially the same as Roku Streaming Stick+. The only difference is the remote that comes with Roku Streaming Stick+ HE. This remote is more robust with enhanced voice commands, a headphone jack, and TV controls. 

Roku Ultra LT – $79.99

Roku Ultra LT is a quad-core processor that syncs to your TV wirelessly. Roku Ultra LT has all the features of Roku Streaming Stick+ HE, including its remote. Roku Ultra LT also hooks up to the internet via an ethernet connection. 

Roku Ultra – $99.99

Roku Ultra is Roku’s highest quality streaming device. It’s an upgraded version of Roku Ultra LT and comes with a few more features. Roku Ultra has USB and microSD ports for extra storage. It also comes with an improved remote complete with shortcut buttons, lost remote finder, JBL headphones for private listening, and a few other upgrades. 

Outside of devices, there’s also Roku 4K TV that lets you stream in 4K Ultra HD and has upscaling technology to improve lower streaming qualities.
