About the Roku Ultra 4800R

Access to the most shows and movies — in full 4K and Dolby Vision

There are so many TV options out there that it's hard to keep up! And now even blockbuster movies are skipping theaters and going straight streaming services — so you want it all to look and sound its best. The Roku Ultra connects to your TV and serves up the largest selection of video content I've seen. That includes the most complete list of 4K and HDR options available in one streaming box. And the 2020 version is the first Roku player that supports content with the advanced HDR format Dolby Vision.

The compact Roku Ultra fits into your TV setup and serves up a ton of streaming 4K and HD channels.

Access to the most shows and movies — in full 4K and Dolby Vision

There are so many TV options out there that it's hard to keep up! And now even blockbuster movies are skipping theaters and going straight streaming services — so you want it all to look and sound its best. The Roku Ultra connects to your TV and serves up the largest selection of video content I've seen. That includes the most complete list of 4K and HDR options available in one streaming box. And the 2020 version is the first Roku player that supports content with the advanced HDR format Dolby Vision.

Netflix, Disney+, and Amazon Prime Video all offer shows in Dolby Vision. Just be warned — ever since I connected a Roku to my LG OLED TV, I've become spoiled. Now I only want to watch visually-striking shows like The Mandalorian, The Boys, and Stranger Things in full 4K and HDR. 

Faster processing and stronger Wi-Fi

This latest version of the Roku Ultra offers the company's fastest processing yet, so you should notice smoother performance and less waiting for content to load. They've included a more powerful dual-band Wi-Fi antenna, too, so you can get a stronger wireless signal. Especially helpful if your wireless router is further away from your TV setup. (Of course, I always recommend getting as close as you can — or better yet, making a wired connection via the Ethernet port.)   


Customize the remote's "1" and "2" button to instantly pull up a favorite channel or playlist.

Do "smart TV" owners need a Roku?

While most 4K TVs have some streaming services baked in, Roku offers the most complete list of 4K options I've seen. Netflix, Hulu, Prime Video, and Vudu are all available in 4K. New video services  and AppleTV+ are also available with 4K and HDR content.   

Plus there's a ridiculous amount of standard HD streaming channels – movie channels, news, kids, sports, you name it. I use my Roku to watch baseball games on MLB.TV and order UFC pay-per-views on ESPN+. I can't watch either on my Smart TV without the Roku. 

"Point anywhere” remote with voice search

Roku's remote communicates over Wi-Fi. That means you can store this player out of sight and still have full control. Hit the "Mic" button on the remote, and just say what show or movie you're looking for. 

Roku also includes a pair of earbuds that connect to the remote, so you can watch TV without disturbing others. I find that's a nice feature to have for late-night movies and west coast sports. I can hear dialogue or play-by-play clearly, and I'm not waking up any of my kids.   

My Roku experience: It's not just for cord cutters

While I've dabbled in cord-cutting, I'm currently a cable subscriber. Still, I call the Roku I bought for my bedroom TV the best bang-for-my-buck purchase I've made in some time. It gives me on-demand shows from my cable channels like FX, HBO, AMC, and more. So I can watch Fargo or Better Call Saul on my own time — without having to rent another cable box.

Remote app with personal listening mode

Roku's free mobile app lets you operate the player using your Apple® or Android™ device. You can setup your player, choose what you want to watch, and control pretty much everything from your phone. You can also connect headphones and hear TV sound.

The 4800R is also equipped with a RJ-45 Ethernet (10/100) jack for a wired connection. The Roku streaming player must be connected to your home network and the internet provider.

  • Roku streaming devices perform well with most home broadband services (DSL or cable internet). Movies and TV shows streamed in higher picture quality formats like 4K or HDR require more bandwidth and therefore need higher internet speeds (up to 25 Mbps). Contact your Internet Service Provider (ISP) for details about the available services in your area.
  • Using a mobile hotspot is not recommended, considering they are generally not as reliable as home broadband.

Entertainment Apps: The Roku Ultra lets you wirelessly stream blockbuster movies, TV shows, live TV, popular broadcast networks, niche channels. TV shows, live sports, news, and music.

  • Many of Roku's free channels are ad-supported, while other paid apps (like Netflix & Amazon Video) are commercial free.
  • Not all content available from a streaming service that supports 4K HDR will appear in 4K HDR. Look for movies or TV shows that are marked with an HDR logo. 4K and HDR content is not available on all channels and may require additional fees.

HDMI 2.0b Output: The Roku Ultra (4800R) is equipped with a rear-panel HDMI 2.0b output with support for 720p HD, 1080p Full HD, 4K Ultra HD (UHD), and 4K HDR video resolution. The HDMI output cannot be set to output 480i, 480p, or 1080i. The HDMI 2.0b output also supports high-resolution multichannel audio transmission; including support for Dolby Digital, DTS, and Dolby Atmos.

  • Ultra-HD 4K Compatible: The term "4K" (also known as 4K Ultra High Definition, 4K Ultra HD, or just 4K UHD) refers to the resolution of the TV, which is a measure of how much detail you can see on the screen. A traditional 1080p high definition TV has 1,920 vertical columns and 1,080 horizontal rows of pixels, while a 4K Ultra HD TV has a total resolution of 3,840 pixels by 2,160. With 4x the resolution of 1080p HD displays, 4K offers improvement in picture clarity over existing HD resolutions.
  • HDR (Dolby Vision + HDR10): The Roku Ultra supports HDR10 and Dolby Vision. HDR (High Dynamic Range) is a technology that helps to expand the range of brightness, contrast, and color significantly. Bright parts of the image can get much brighter with better color accuracy, while dark parts of the image can get much darker improving the contrast. Overall, the image is more natural looking with a greater sense of depth.
  • Dolby Atmos: In addition to Dolby Digital and DTS, the Roku Ultra (4800R) offers supports for Dolby Atmos so it can output the Dolby Atmos immersive 3D surround format from select apps (such as Netflix, Disney+, and Vudu) to your HDMI connected AV receiver and home theater speaker system.

Can Roku Ultra stream the highest resolution audio from Amazon or Tidal and the like?
[ Rodney  Nov 27, 2020 ]
2 answers
No! Roku can stream Tidal etc but not even close to Hi Res or MQA quality. Roku won't reveal their streaming resolution but it is less than CD quality, probably similar to Spotify. Roku is a good all purpose streaming platform, especially for video. But for true Hi Res audio you will need a quality streaming device like the Bluesound N130 as well as an external DAC.
[ FDW-NM  May 25, 2022 ]
Yes. As long as you have the right av equipment to process the stream, you will be able to enjoy the highest resolution audio and video. I have been streaming Amazon and Disney+ with sucess.
