For most buyers, the Roku Ultra is the best Roku for 4K, Dolby Vision, and fast performance. It is the only model in this group with Wi-Fi 6, Ethernet, USB media playback, Dolby Atmos support, a rechargeable Voice Remote Pro, and Roku’s claim that it is 30% faster than any other Roku device. Choose the Roku Streaming Stick 4K when you want Dolby Vision in a small, TV-hidden design without paying for Ultra’s ports and premium remote. Choose the Streaming Stick Plus when you want the least expensive 4K Roku and your TV does not require Dolby Vision.
The important qualification is generation: Roku has released a new Ultra that replaces the 2024 model reviewed by Tom’s Guide. Independent testing of the newest version is still pending, so check the model and current price before ordering.
Quick answer: which Roku should you buy?
Your TV, audio system, network, and preferred HDR format matter more than the Roku logo on the box. Use this short list to narrow the choice:
- Buy Roku Ultra for the fastest navigation, Dolby Vision and Dolby Atmos, wired Ethernet, Wi-Fi 6, USB playback, and the broadest feature set.
- Buy Roku Streaming Stick 4K for Dolby Vision in a compact stick that hides behind the television, provided Wi-Fi is sufficient and you do not need Ethernet or USB media playback.
- Buy Roku Streaming Stick Plus for lower-cost 4K HDR when HDR10, HDR10+, and HLG are enough. It does not support Dolby Vision or Dolby Atmos.
All three can play 4K video at up to 60 frames per second when the TV, application, HDMI connection, and content support it. The differences are HDR format, processing headroom, networking, audio features, ports, remote controls, and price.

Roku 4K models compared
Roku’s comparison page lists US prices of $59.99 for Streaming Stick Plus, $79.99 for Streaming Stick 4K, and $149.99 for Roku Ultra as of October 20, 2026. Those are current list prices, not guaranteed checkout prices. TechRadar reported on July 26, 2026, that Roku’s US list prices had risen to those levels while sale prices could still appear.
| Model | Release and hardware | Maximum video formats | Audio and networking | Ports and remote | US list price (Roku, accessed October 20, 2026) |
|---|---|---|---|---|---|
| Roku Streaming Stick Plus (3830X) | Released 2025; ARM Cortex-A55; 1 GB RAM | 4K at 60 fps; HDR10, HDR10+, and HLG; no Dolby Vision | Dolby-encoded pass-through and DTS Digital Surround; dual-band 802.11ac Wi-Fi | USB-C power; no Ethernet or USB media port; standard stick form factor | $59.99 |
| Roku Streaming Stick 4K (3820X2) | Released 2022; ARM Cortex-A55; 1 GB RAM | 4K at 60 fps; HDR10, HDR10+, HLG, and Dolby Vision | Dolby and DTS support; the comparison page does not document Ultra-level Dolby Atmos features; long-range dual-band Wi-Fi | HDMI stick; no Ethernet or USB media port | $79.99 |
| Roku Ultra (4850X) | Released 2024 specification; ARM Cortex-A55; 2 GB RAM. A newer Ultra has replaced the model reviewed by Tom’s Guide. | 4K at 60 fps; HDR10, HDR10+, HLG, and Dolby Vision | Dolby Atmos, Dolby Audio, and Bluetooth Headphone Mode; Wi-Fi 6 plus 10/100 Ethernet | USB media playback; separate player that sits near the TV; rechargeable Voice Remote Pro | $149.99 |
The processor family is the same ARM Cortex-A55 across the listed models, but Ultra has twice the listed memory. Roku advertises Ultra as its fastest player, claiming it is 30% faster than any other Roku device. That is Roku’s own product claim, not an independently measured benchmark.
Roku Ultra: best for speed, Dolby Vision, and a complete setup
Why Ultra is the premium pick
Ultra is the most capable option when you want one Roku to cover demanding video, audio, networking, and local-media needs. It supports Dolby Vision as well as HDR10, HDR10+, and HLG, so it can match the HDR formats used by current 4K televisions and streaming services. It also supports Dolby Atmos, provided the soundbar or AV receiver and the content support Atmos.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Its 2 GB of RAM gives it more listed memory than either stick. Roku’s 30% faster statement should be read as a manufacturer comparison rather than a laboratory result, but Tom’s Guide independently described Ultra navigation as incredibly fast. That distinction matters if you frequently switch apps, open large menus, or use search rather than launching one service and leaving it running.
Connections that sticks cannot provide
Ultra adds Wi-Fi 6 and a 10/100 Ethernet port. Ethernet is useful when the player is close to a router, when walls or distance weaken Wi-Fi, or when a busy household makes wireless performance inconsistent. Wi-Fi 6 can also help in a congested wireless environment, although the result still depends on your router, placement, internet service, and other devices.
The USB port enables playback of compatible local media, a feature Tom’s Guide identifies as unique in the Roku line. That makes Ultra a better fit for a personal media collection on a USB drive. The sticks do not provide the same USB media feature.

What you give up
Ultra is a separate set-top player rather than a small stick hidden behind the TV, so it needs a visible shelf or other stable location near the television. It costs $149.99 at Roku’s listed US price, nearly twice the Streaming Stick 4K and more than twice the Streaming Stick Plus. The newest Ultra also has less independent test data available than the outgoing 2024 model. Tom’s Guide advises waiting for testing of the replacement or buying the outgoing unit only when a discount makes the uncertainty worthwhile.

1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsRoku Streaming Stick 4K: the compact Dolby Vision choice
Who should choose it
Streaming Stick 4K is the straightforward answer to the question, “Which Roku supports Dolby Vision without a set-top box?” It supports Dolby Vision, HDR10, HDR10+, and HLG, and its HDMI stick design leaves little hardware visible around the television. Roku positions it for 4K and Dolby Vision with stronger long-range Wi-Fi than a basic wireless setup.
At $79.99 on Roku’s current US comparison page, it costs $20 more than Streaming Stick Plus. That premium buys Dolby Vision support and the compact model aimed at longer wireless links, not Ethernet, USB playback, or Ultra’s full remote and audio feature set.
Limits to check before buying
Streaming Stick 4K depends on Wi-Fi. It has no Ethernet port, so it cannot use a wired network without an additional networking arrangement that Roku does not present as an integrated feature. It also has no USB media port. If either is a requirement, move to Ultra.
The comparison information documents Dolby and DTS support but does not list the Ultra-level Dolby Atmos feature set for this stick. If your sound system specifically requires Atmos from the Roku, Ultra is the safer choice. Confirm the capabilities of the exact application, soundbar, receiver, and television before assuming that a format supported by a streaming service will reach your speakers.
Roku Streaming Stick Plus: the value 4K HDR model
What it does well
Streaming Stick Plus is the least expensive of the three at Roku’s listed US price of $59.99. It uses an ARM Cortex-A55 processor, 1 GB of RAM, and dual-band 802.11ac Wi-Fi. It plays 4K video at up to 60 fps and supports HDR10, HDR10+, and HLG.

Tom’s Guide’s 2026 buying guide found 4K video on Streaming Stick Plus to be hitch-free, with no browsing hang-ups during its testing. The guide names it the best Roku under $40, an editorial category label rather than a measured market statistic. Because Roku’s current list price is $59.99, that recommendation makes the most sense when a sale brings the stick below that threshold.
The format and feature trade-offs
Streaming Stick Plus does not support Dolby Vision. It also does not support Dolby Atmos, Ethernet, USB media playback, or the premium remote features included with Ultra. Choose it when your television uses HDR10-family formats, your wireless network is reliable, and you do not need local files or a wired connection.
Dolby Vision, HDR10, HDR10+, and HLG explained
Dolby Vision is the deciding feature for many 4K buyers
Dolby Vision is a dynamic HDR format that some televisions and streaming titles use to adjust picture information scene by scene. In this lineup, only Streaming Stick 4K and Ultra support it. Streaming Stick Plus cannot output Dolby Vision, even if the television itself is Dolby Vision-capable.
Quick wins for a faster PC:
Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →A Dolby Vision television can still display HDR10 content, but that does not make a non-Dolby-Vision Roku equivalent to one that can send Dolby Vision titles. If Dolby Vision is a firm requirement, eliminate Streaming Stick Plus before considering price or size.
The other HDR formats
All three models support HDR10, HDR10+, and HLG according to Roku’s hardware documentation. HDR10 is the widely supported baseline. HDR10+ adds dynamic metadata on compatible televisions and content, while HLG is commonly associated with broadcast and live-video workflows. Actual playback depends on the title, application, television, and the negotiated HDMI connection.
Performance: what “faster” means in everyday use
Streaming performance and interface performance are related but not identical. A fast internet connection can deliver a 4K stream, while the Roku processor and memory affect how quickly menus open, searches respond, applications resume, and the home screen redraws.

Ultra has 2 GB of RAM versus 1 GB in each stick and carries Roku’s 30% faster claim. Tom’s Guide reports that Ultra navigation feels incredibly fast, while its Streaming Stick Plus testing found smooth 4K playback and no browsing hang-ups. Those observations support Ultra as the smoother premium choice, but they do not establish a universal frame-rate or loading-time advantage for every app. The new Ultra replacing the reviewed 2024 model still needs current independent testing.
For a household that mostly opens one or two services and watches a program, Streaming Stick Plus may be responsive enough. For frequent multitasking, a large app library, rapid searching, or a preference for the quickest interface available, Ultra has the stronger specification and testing case.
Networking, audio, and ports: the practical differences
| Need | Streaming Stick Plus | Streaming Stick 4K | Roku Ultra |
|---|---|---|---|
| Wireless connection | Dual-band 802.11ac Wi-Fi | Long-range dual-band Wi-Fi | Wi-Fi 6 |
| Wired Ethernet | No | No | Yes, 10/100 |
| USB media playback | No | No | Yes |
| Dolby Vision | No | Yes | Yes |
| Dolby Atmos | No | Not documented as an Ultra-level feature on Roku’s comparison information | Yes |
| Bluetooth Headphone Mode | Not stated | Not stated | Yes |
When Ethernet is worth paying for
Choose Ultra’s Ethernet connection when the television is near the router and you want to avoid wireless interference, or when a long distance and several walls make Wi-Fi unreliable. Ethernet does not increase the speed of an internet plan; it can make the link between the player and router more consistent.
When Atmos support matters
Dolby Atmos requires more than an Atmos-capable Roku. The content must carry an Atmos track, the streaming application must pass it through, and the television, soundbar, or receiver must decode or forward it correctly. Ultra is the model in this comparison that explicitly lists Dolby Atmos. If your system is stereo or limited to basic Dolby/DTS playback, paying for Ultra solely for Atmos may not change what you hear.
When USB playback matters
Ultra’s USB port is useful for compatible files stored locally. The sticks do not offer the same USB media function, so a household that watches downloaded or personally recorded files should account for that before choosing a smaller model.

Compatibility and setup requirements
Roku states that Ultra can work with any TV that has HDMI, but advanced formats depend on the rest of the signal chain. A TV must support 4K for 4K output, support the relevant HDR format for HDR playback, and expose the correct HDMI mode. Dolby Atmos additionally requires compatible audio equipment.

Before you connect the Roku
- Confirm that the television has an available HDMI input. For 4K HDR, use a high-speed HDMI connection suitable for the TV’s stated format.
- Check the TV’s specifications for 4K at 60 fps and the HDR formats it accepts. A Dolby Vision Roku cannot add Dolby Vision to a TV that lacks Dolby Vision support.
- For Ultra, decide whether Ethernet or Wi-Fi 6 fits the installation. For either stick, verify that the intended location receives a dependable dual-band Wi-Fi signal.
- If you want Atmos, verify support on the soundbar or receiver and identify whether the Roku connects directly to that device or through the television.
- Allow adequate internet bandwidth for stable 4K streaming. The exact requirement varies by service and household traffic, so do not treat the Roku model alone as a guarantee of uninterrupted playback.
Basic setup procedure
- Connect the Roku to an HDMI input. Plug in the supplied power connection; the sticks use USB-C power, while Ultra sits as a separate player.
- On the TV, select the HDMI input used by the Roku and follow the on-screen pairing instructions for the remote.
- Join the home network. Select Ethernet during setup if using Ultra’s wired port; otherwise choose the appropriate Wi-Fi network and enter its password.
- Allow the Roku to check for software updates, then sign in to or add the streaming services you use.
- Open the display settings and confirm the detected resolution and HDR behavior. Play a known 4K HDR title to verify that the television reports the expected format.
- If using an Atmos system, check the soundbar or receiver’s input display while playing an Atmos title. If it reports only stereo or basic Dolby, inspect the TV’s HDMI audio setting and the connection path.
How to choose in common buying situations
You have a Dolby Vision television and want the smallest device
Choose Streaming Stick 4K if Wi-Fi is dependable and you do not need USB playback, Ethernet, or the Ultra remote. It provides Dolby Vision in the compact stick form factor.
You have a Dolby Vision television, a soundbar, and a busy network
Choose Ultra. Its explicit Dolby Atmos support, Wi-Fi 6, and Ethernet address the audio and connectivity requirements that make the smaller stick a compromise.
You have a 4K HDR10 television and want to spend as little as possible
Choose Streaming Stick Plus, especially when a sale price puts it below Roku’s $59.99 list price. Its HDR10, HDR10+, and HLG support covers the formats your TV can use, but it will not provide Dolby Vision later if you upgrade to a compatible television.
You keep local video files on a USB drive
Choose Ultra because USB playback is the feature identified for that model. Neither stick provides the same USB media port.
You want the fastest interface but do not need Dolby Vision
Ultra remains the performance choice because it has 2 GB of RAM, Roku’s 30% faster claim, and positive independent comments about navigation. Whether that premium is worthwhile depends on how often you notice menu delays and how much the $149.99 list price matters.
You plan to hide the player behind a wall-mounted TV
Choose one of the sticks if the installation has reliable Wi-Fi and no requirement for wired networking or USB media. Ultra’s separate box needs a suitable location and cable routing.
Common problems and fixes
The TV shows 1080p instead of 4K
- Confirm that the selected HDMI input supports the television’s 4K mode; some sets reserve full-bandwidth features for specific inputs or settings.
- Replace an unsuitable or damaged HDMI cable with a high-speed cable appropriate for 4K HDR.
- Check the Roku display setting after the TV and Roku have negotiated the connection.
- Verify that the title and streaming plan actually provide 4K. A 4K-capable player cannot turn an HD stream into native 4K.
Dolby Vision does not activate
- Make sure the Roku model is Streaming Stick 4K or Ultra. Streaming Stick Plus does not support Dolby Vision.
- Confirm that the TV supports Dolby Vision and that the HDMI path does not pass through equipment limited to another format.
- Check the application and title; not every 4K program uses Dolby Vision.
4K playback buffers or drops quality
- Test the Roku near the router or use Ultra’s Ethernet connection if the installation allows it.
- Reduce competing traffic on the network and check for interference affecting a stick’s Wi-Fi signal.
- Confirm that the internet connection has enough available bandwidth for 4K while other household devices are active.
The interface feels slow
- Restart the Roku and allow pending software updates to complete.
- Remove applications you no longer use if the home screen is crowded.
- If responsiveness is the deciding factor and the problem persists, Ultra is the model with the higher memory allocation and the strongest published performance case.
Atmos is not reaching the soundbar
- Verify that the title, application, subscription, and soundbar or receiver all support Dolby Atmos.
- Check whether the Roku connects directly to the audio device or through the TV, then enable the TV’s appropriate HDMI audio pass-through option if required.
- Use Ultra when you need a Roku model that explicitly lists Dolby Atmos support; the comparison information does not document the same Ultra-level feature set for Streaming Stick 4K.
Price and generation caveats for 2026
Roku’s current US list prices are $59.99 for Streaming Stick Plus, $79.99 for Streaming Stick 4K, and $149.99 for Ultra. TechRadar’s July 26, 2026 pricing report noted that those list prices had increased while sale prices could remain lower. Treat retailer stock and promotions as temporary: check the final checkout price and the model number.
Recommended Free Tools
Ultra requires extra caution because a new generation has replaced the 2024 unit reviewed by Tom’s Guide. The 4850X specification lists a 2024 release, but the current retail product may be the newer replacement. If you buy the outgoing model, the discount should compensate for choosing hardware with less current testing coverage. If you want the newest Ultra’s behavior documented independently, wait for updated testing.
Final buying verdict
Roku Ultra is the best all-around Roku for a 4K television when you value speed, Dolby Vision, Dolby Atmos, a stable wired option, Wi-Fi 6, USB playback, and the rechargeable Voice Remote Pro. Streaming Stick 4K is the better physical design for Dolby Vision buyers who want a hidden HDMI stick and can live with Wi-Fi-only networking. Streaming Stick Plus is the sensible value purchase for 4K HDR10-family televisions, but its lack of Dolby Vision and Atmos makes it the wrong choice for a format-specific upgrade.
