Our take on the Roku Ultra 4660R

I know from experience — when you get a 4K TV, you want to watch shows and movies that really show off the picture. After I purchased an OLED TV, I became spoiled and now can only watch Stranger Things in 4K. (For me, the rich imagery adds even more texture — and extra dread — to the story-telling.) The Roku Ultra connects to your TV and serves up the largest selection of 4K and HDR streaming video services, movies, and shows available in one “box.”

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

Stream 4K/HDR video with Roku's best player

I know from experience — when you get a 4K TV, you want to watch shows and movies that really show off the picture. After I purchased an OLED TV, I became spoiled and now can only watch Stranger Things in 4K. (For me, the rich imagery adds even more texture — and extra dread — to the story-telling.) The Roku Ultra connects to your TV and serves up the largest selection of 4K and HDR streaming video services, movies, and shows available in one “box.”

Roku app

Roku's unbiased search finds the cheapest way to watch your favorite shows.

"Point anywhere” remote with headphone jack

Roku's redesigned remote is easy to use and can even control your TV's volume. Since the remote communicates over Wi-Fi, you can store the player out of sight and still have full control. Worried about keeping track of another clicker? You can press the "find my remote" button on the Roku Ultra, and the remote will make a sound.

The remote also has a 3.5mm headphone jack for personal listening. Use your own headphones or the included earbuds and watch TV without disturbing others.

Unbiased search — with your voice

The remote also features voice control. Tap the voice search button on the remote, and call out the name of a movie, show, or actor. Roku's “unbiased search” will hunt through the top channels for the cheapest way to watch. That's pretty handy for cost-conscious cord-cutters who no longer pay for cable.

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, Amazon Instant Video, and Vudu are all available in 4K. Plus there's a ridiculous amount of standard HD streaming channels – movie channels, news, kids, sports, you name it.

The Roku Ultra also has a snappy interface, thanks to its quad-core processing. You can breeze through the menu and swiftly load up channels. If you're looking for a particular show or movie,

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 all year. 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.

Plus, late at night, I can plug my headphones into the remote and listen at a volume where dialogue is still clear. That's how I recently re-watched The Sopranos, binging through the first two seasons after my wife went to sleep. (The show still holds up, by the way.)

Quick and easy setup

The Roku Ultra connects to your TV via a single HDMI cable. Then it connects to your network wirelessly via Wi-Fi. You log on, type in your Wi-Fi password, and that's basically it — all the instructions are on-screen. (Or, plug it into your router and network hub with an Ethernet cable.)

Remote app with personal listening mode

Roku's free mobile app lets you operate the player using your Apple® or Android™ device. Choose what you want to watch and control video playback from your phone. You can also connect headphones and hear TV sound, just like with the remote.

Contact your Internet Service Provider (ISP) for details about the available services in your area.

  • Many of Roku's free channels are ad-supported, while other paid apps (like Netflix & Amazon Video) are commercial free.

HDMI 2.0a Output: The Roku Ultra (4660R) is equipped with a rear-panel HDMI 2.0a output with support for 720p HD, 1080p Full HD, 4K Ultra HD (UHD), and 4K HDR video resolution.

  • 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 (High Dynamic Range) Video: The Roku Ultra supports HDR 10. 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.
