1. Highwings 8K 10K 4K HDMI Cable – Balanced HDMI 2.1 Performance

4.7Editor scoreCheck price on Amazon

Highwings 8K 10K 4K HDMI Cable

Certified 48Gbps bandwidth

8K at 60Hz

4K at 120Hz

6.6-foot braided cable

The Highwings 8K 10K 4K HDMI Cable is a 6.6-foot, certified ultra-high-speed cable built around a stated 48Gbps bandwidth. Its 4.7 rating and broad support for 8K at 60Hz, 4K at 120Hz, and 4K at 240Hz make it a capable all-round option for a Roku Ultra connected to a modern television or projector. Backward compatibility extends its usefulness to older HDMI equipment as well.

Pros

• Certified ultra-high-speed specification
• Strong high-resolution support
• Reinforced anti-bending connector design
• Backward compatibility with older HDMI
• Supports variable refresh rate

Cons

• Single cable rather than multipack
• No explicit Roku Ultra listing

Its standout qualities are a combination of strong headline bandwidth and practical construction. The cable is described as HDMI 2.1, supports variable refresh rate, and uses an upgraded anti-bending connector-tail design along with military-grade tensile nylon. Those details matter in an entertainment center because a cable often bends sharply as it travels behind a television stand, while its specifications leave room for demanding source and display combinations.

The main trade-off is that this is one 6.6-foot cable rather than a two-cable bundle. That may be perfectly sensible for a single Roku Ultra connection, but it offers less flexibility if you also need a replacement, a second television, or a cable routed through a different location. The product information also does not explicitly name Roku Ultra, although standard HDMI connectivity and backward compatibility make it a logical fit for that device.

This is a strong recommendation for buyers who want recognized ultra-high-speed certification, generous bandwidth, and a conventional 6.6-foot length without moving to the longest cable in the guide. It may be especially useful for a newer 4K television, a high-refresh-rate display, or a setup that will later be connected to other HDMI 2.1 devices. For a straightforward Roku Ultra installation, it provides a capable and well-rounded balance.

Headroom for Advanced Displays

A stated 48Gbps bandwidth and support for 8K at 60Hz and 4K at 120Hz provide useful headroom. The actual resolution and refresh rate remain limited by the Roku Ultra, television, and any connected source, but the cable does not appear to impose a lower ceiling.

Designed for Everyday Routing

The reinforced connector tail and tensile nylon construction target the bending and pulling that occur behind furniture. That makes the 6.6-foot length suitable for many setups where the Roku Ultra sits near, but not directly beside, the television.

Highwings 8K HDMI 2.1 2-Pack

Two certified 48Gbps cables

8K at 60Hz

4K at 120Hz

6.6-foot cable length

The Highwings 8K HDMI 2.1 Cable 2-Pack provides two 6.6-foot certified ultra-high-speed cables, each with a stated 48Gbps bandwidth and a 4.7 rating. For a Roku Ultra owner, the two-cable format is useful because one cable can connect the streaming box while the second provides a spare, serves another display, or replaces a cable routed through a less convenient path.

Pros

• Includes two matching cables
• Certified 48Gbps performance
• Aluminum alloy connector shells
• Supports variable refresh rate
• Backward compatible with HDMI

Cons

• More cable than one setup requires
• No explicit Roku Ultra mention

We may earn a commission when you buy through this link, at no additional cost to you.

Each cable supports 8K at 60Hz, 4K at 120Hz, 4K at 240Hz, and 10K according to the listed information. The construction uses upgraded aluminum alloy shells and anti-bending connector tails, while the nylon exterior is intended to improve durability. Variable refresh rate support makes the package more relevant to mixed entertainment setups that include capable gaming hardware and displays.

Because this is a two-pack, it may be more than necessary for someone who only needs a single direct connection. It also does not explicitly identify Roku Ultra in the supplied listing, so buyers should verify the physical HDMI connectors and compatibility rather than relying on branding. Nevertheless, a standard HDMI 2.1 cable is directly relevant to the streaming box, and the listed backward compatibility broadens the possible uses.

Choose this option when you value having a matching second cable nearly as much as the first. It is a particularly convenient choice for moving a Roku Ultra between a television and a projector, routing cables through furniture, or maintaining a spare connection. Buyers seeking only one straightforward cable may find a single-cable option cleaner, while those who want installation flexibility will appreciate the bundle.

A Spare Solves Many Setup Problems

Keeping a second 6.6-foot cable can eliminate the need to unplug and reconnect the Roku Ultra when moving it or changing a route. It is also useful for a second television, projector, or soundbar arrangement.

Shared Performance Across Both Cables

The package is described as two certified ultra-high-speed HDMI 2.1 cables with 48Gbps bandwidth. Buyers get matching specifications rather than one primary cable and a less capable backup.

Ubluker 10K 8K 4K HDMI Cable

48Gbps ultra-high-speed bandwidth

8K at 60Hz

4K at 240Hz

6.6-foot cable length

The Ubluker 10K 8K 4K HDMI Cable combines a 4.7 rating with official HDMI certification and a stated 48Gbps bandwidth. The 6.6-foot cable is listed for 10K at 60Hz, 8K at 60Hz, 4K at 120Hz, and 4K at 240Hz, giving a Roku Ultra setup a wide performance ceiling even though the streaming box itself will not generate every advertised mode.

Pros

• Official HDMI certification label
• Extensive feature compatibility list
• Broad high-resolution support
• Advanced audio format support
• Explicit Roku TV compatibility

Cons

• Dense specification list may intimidate buyers
• Roku TV is named rather than Roku Ultra

We may earn a commission when you buy through this link, at no additional cost to you.

The product information is unusually detailed. It lists VRR, ALLM, QMS, QFT, Dynamic HDR, HDR10+, CEC, HDCP 2.2 and 2.3, and DSC 1.2a. It also supports eARC, ARC, DTS Master, DTS:X, Dolby TrueHD, Dolby Vision, and Dolby Atmos. For a home theater, the audio and HDR support is more relevant than maximum gaming refresh rates, particularly when the HDMI path continues to a soundbar or receiver.

Compatibility is broad and explicitly includes Roku TV, along with gaming PCs, consoles, Apple TV, televisions, projectors, monitors, and other streaming services. The wording does not directly name Roku Ultra, which may lead cautious buyers to confirm fit and expected functions. It also does not emphasize connector materials or bend testing as strongly as some competing listings, so the buyer is choosing primarily on certification and feature coverage.

This cable is a strong candidate for a Roku Ultra owner who wants one cable that combines certification, high-resolution capability, and modern audio functions. It is particularly attractive when the Roku connects through a soundbar or receiver and the setup may later include HDR-capable content. For the average user, the long feature list is reassuring rather than something that must be fully understood to use the connection.

Modern Audio and Video Features

Support for eARC, ARC, Dolby Atmos, Dolby Vision, and Dynamic HDR makes the cable relevant to connected soundbars and receivers. These functions still require compatible hardware, but the cable can carry the associated signals when the rest of the system supports them.

Certification Gives Clearer Confidence

The official HDMI certification label and stated compliance with HDMI Forum requirements offer a more concrete basis for comparison than a cable that only advertises maximum resolution. Certification also covers the overall specification rather than one isolated feature.

The Anker HDMI 2.1 Cable is a 6.6-foot ultra-high-speed cable with a 4.8 rating, making it one of the strongest-rated products in this guide. It provides 48Gbps bandwidth, supports 8K at 60Hz and 4K at 120Hz, and is explicitly listed as compatible with Roku Ultra. That direct device mention makes it one of the clearest options for readers shopping by product rather than by technical specification alone.

Pros

• Highest listed rating in guide
• Explicit Roku Ultra compatibility
• Official HDMI Forum certification
• Double-braided nylon exterior
• Gold-plated connector pins

Cons

• Costs more than many alternatives
• 18-month warranty is listed

We may earn a commission when you buy through this link, at no additional cost to you.

Its construction is a major differentiator. The cable uses carbon steel connectors, gold-plated pins, and a double-braided nylon finish. Anker states that the materials are designed to withstand 10,000 plug-and-unplug cycles. It is also among the first officially certified ultra-high-speed HDMI cables mentioned in the supplied information, with electromagnetic-interference protection addressed through certification testing.

The trade-off is its higher position in the market compared with many generic and value-oriented cables. The listed package also includes an 18-month warranty and customer support rather than a lifetime warranty, so buyers who prioritize long-term coverage may want to examine that distinction. For a Roku Ultra, however, a high-quality certified cable can be reassuring in a setup where the box and display are expected to remain connected for extended periods.

This is the most directly matched recommendation in the guide for someone who wants a polished, well-known cable and sees the product description mentioning Roku Ultra. It suits a modern 4K television, projector, or monitor and provides ample bandwidth for future display upgrades. Choose it when construction quality, certification, and explicit Roku Ultra support justify spending more than the cost of a basic cable.

Directly Suited to Roku Ultra

The supplied product information specifically names Roku Ultra as a supported device. That removes any need to infer compatibility from a generic streaming-device list, although the physical connection still uses the standard HDMI format.

Materials for Repeated Daily Use

Gold-plated connector pins, carbon steel connector bodies, and a double-braided nylon jacket target durability. These details are particularly relevant for a streaming cable that may remain plugged in but also need to survive occasional repositioning.

Silkland Certified HDMI 2.1 Cable

48Gbps ultra-high-speed bandwidth

8K at 60Hz

4K at 144Hz

6.6-foot braided cable

The Silkland Certified HDMI 2.1 Cable is a 6.6-foot braided cable rated 4.7, with a stated 48Gbps bandwidth and HDMI 2.1 certification that can be verified using a QR-code scanner. It supports 10K, 8K at 60Hz, 5K at 120Hz, 4K at 144Hz, and 4K at 120Hz. That range makes it a capable cable for a Roku Ultra setup shared with capable gaming hardware or a high-performance display.

Pros

• Verifiable HDMI 2.1 certification
• Supports 4K at 144Hz
• E-Braid double-layer construction
• Dynamic HDR support
• eARC and ARC support

Cons

• Some high-end modes require compatible hardware
• Customer-care response is a stated priority

We may earn a commission when you buy through this link, at no additional cost to you.

Its E-Braid construction uses double-layer fishnet winding and nylon braiding, while copper cores and ferrite magnetic beads are intended to support consistent signal transmission. The cable also supports dynamic HDR, HDCP 2.2 and 2.3, DTS:X, Dolby Atmos, and eARC or ARC. Those are valuable additions for a living-room entertainment system where audio may pass through a soundbar or receiver.

Some advertised resolution and refresh-rate combinations depend on a source and display that support them, and a Roku Ultra will not reproduce 4K at 144Hz simply because the cable can carry it. Buyers should also evaluate whether the extensive gaming-oriented specification provides meaningful value if the cable is only serving streaming. The verification method for certification is a positive feature, but a QR-code scan is an additional step during setup.

Choose this cable when you want a well-rounded HDMI 2.1 connection that can serve streaming, gaming, and modern audio in one setup. It is appropriate for users who expect to connect a Roku Ultra to a television, monitor, projector, or soundbar and appreciate an emphasis on verified certification and layered cable construction.

Verification Adds Transparency

The stated HDMI 2.1 certification can be checked by scanning the cable's QR code. For buyers wary of exaggerated bandwidth claims, this provides a more tangible verification point than resolution labels alone.

Layered Protection for Signal Integrity

Copper cores, ferrite magnetic beads, and double-layer fishet and nylon braiding are all intended to support stable transmission. The design is especially relevant around powered entertainment equipment where electromagnetic interference can be a concern.

It is explicitly compatible with Roku devices, making it a practical option for linking a Roku Ultra with a television, projector, monitor, or soundbar.

Pros

• Broad resolution and refresh support
• Backward compatible with older HDMI
• eARC and ARC support
• Braided jacket resists daily wear
• Explicit Roku compatibility

Cons

• No official certification stated
• Maximum gaming modes require compatible devices

We may earn a commission when you buy through this link, at no additional cost to you.

The listing covers both video and audio use cases. It supports eARC and ARC, Dolby Vision, Dolby Atmos, and VRR on compatible hardware. Its construction combines a high-purity copper core, aluminum alloy shells, and a braided jacket intended to resist electromagnetic interference, bending, and daily wear. The cable also remains backward compatible with HDMI 2.0, 1.4, 1.3, and 1.2 devices.

One consideration is that official HDMI certification is not stated in the supplied product information. That does not negate the listed 48Gbps capability, but it gives certified alternatives a distinct documentation advantage. The advanced refresh rates are also mostly relevant to gaming devices and displays rather than the streaming experience itself. For most Roku Ultra installations, the real-time 4K streaming and audio path will be less demanding.

This cable is recommended for buyers who want a clearly compatible, well-constructed HDMI 2.1 option that can serve more than one entertainment role. It is especially suitable when the Roku Ultra shares a setup with a gaming console or PC. A buyer who places a higher value on official certification can choose the Anker, UGREEN, Ubluker, or another clearly certified option instead.

One Cable for Multiple Entertainment Roles

With support for gaming refresh rates, HDR-related audio, and mainstream streaming connectivity, the Acer cable can remain useful when a Roku Ultra shares an entertainment center with a console or computer. Its backward compatibility further extends that usefulness.

Practical Braided Construction

The copper core, aluminum shell, and braided jacket form a practical construction package for regular use. These materials are intended to maintain signal quality and withstand the routine bending involved in connecting entertainment equipment.

This cable is particularly well rounded for home entertainment. Dynamic HDR with 12-bit color is listed, while eARC can carry full-resolution audio such as Dolby Atmos and DTS:X to a compatible soundbar or receiver. It also supports HDCP 2.3, HDCP 2.2, Ethernet, and 3D. Compatibility includes Roku devices along with Apple TV, gaming consoles, TVs, projectors, monitors, computers, and other streaming hardware.

Construction uses an aluminum alloy case, nickel-plated connectors, and a durable nylon braided jacket. The stated design is intended to survive repeated bending without sacrificing flexibility. As with the other high-specification options, the cable cannot create resolution, refresh rate, HDR, or audio formats that the Roku Ultra and television do not support, and the most advanced modes may require compatible gaming hardware.

This is a compelling pick for buyers who want certification, strong rating, broad compatibility, and a capable feature set without moving to the premium end of the market. It is especially suitable for a Roku Ultra connected to a modern 4K television or a soundbar-equipped home theater. Its 6.6-foot length also gives enough flexibility for most furniture arrangements without the routing complexity of a much longer cable.

Certified Performance Without Premium Positioning

HDMI 2.1 certification and 48Gbps bandwidth provide a strong foundation while the cable remains more value-focused than the top premium selection. The result is a practical combination for users who prioritize capability per dollar.

Audio Features for Connected Soundbars

eARC, Dolby Atmos, and DTS:X support can be valuable when the Roku Ultra feeds a compatible television or soundbar setup. The feature only works as intended when every device in the audio chain supports the relevant function.

We may earn a commission when you buy through this link, at no additional cost to you.

The cable targets connected home-entertainment setups. It supports eARC, HDR10, VRR, Dolby Vision, Dolby Atmos, DTS:X, and HDCP 2.2 and 2.3. The listing also mentions compatibility with soundbars, Apple TV, Roku devices, gaming consoles, and monitors. A hologram sticker identifies it as an ultra-high-speed HDMI cable, adding a visible certification marker to the package.

The primary limitation is length. A five-foot cable is convenient for a compact stand and reduces excess cable clutter, but it offers less freedom when the Roku Ultra is several feet from the display, behind a larger wall-mounted television, or in a cabinet with an awkward connection path. A six-and-a-half-foot option would provide more positioning flexibility in many homes. The very high advertised modes also depend on compatible source and display equipment.

This Zeskit cable is a good recommendation when your components are close and you want a concise, certified connection rather than an extra-long run. It is particularly appropriate for a living-room setup with a soundbar, television, and Roku Ultra grouped together. Buyers with more difficult routing should compare the five-foot length carefully against the room layout before deciding.

A Cleaner Connection for Compact Areas

The five-foot length can reduce excess slack behind a television stand. It is a practical match when the Roku Ultra, television, and soundbar are arranged within a relatively small entertainment unit.

Home-Theater Functions in One Cable

eARC, HDR10, Dolby Vision, Dolby Atmos, and VRR coverage gives the cable broad relevance. Roku Ultra users can take advantage of the audio and video functions that their television, soundbar, and source equipment are designed to support.

Its length and slim profile make it a convenient direct connection for a Roku Ultra placed immediately beside or below a television.

Pros

• Short and easy to route
• Slim braided construction
• Dynamic HDR and eARC support
• Gold-plated connector
• Explicit Roku Ultra compatibility

Cons

• Shortest length in the guide
• Highest modes require DSC-compatible devices

We may earn a commission when you buy through this link, at no additional cost to you.

The feature set extends beyond raw bandwidth. Dynamic HDR, eARC, DTS Master, DTS:X, Dolby Atmos, VRR, QMS, ALLM, and SBTM are included in the stated support. A gold-plated connector, 30AWG copper wire, triple tin shielding, and nylon braiding form the construction package. The cable is also listed as compatible with Roku Ultra, Apple TV 4K, PlayStation 5, Xbox Series X, Fire TV, Blu-ray players, displays, and projectors.

Four feet is the shortest option shown, so placement is the central trade-off. It works well for compact media cabinets and direct connections, but it can be too restrictive for wall-mounted televisions, larger furniture, or a Roku Ultra positioned farther from the display. The listing also notes that 10K at 30Hz and 8K at 60Hz require source and display support for Display Stream Compression, an important qualification when assessing maximum specifications.

This is a good fit for a nearby streaming device where easy routing and reduced cable clutter matter more than maximum reach. A Roku Ultra owner with a compact setup can benefit from the direct compatibility and broad modern-feature support. If the components are more than a few feet apart, a 5-foot, 6.6-foot, or 15-foot alternative will usually be easier to position.

Minimal Clutter Near the Display

A four-foot cable is easy to conceal behind a compact television stand and avoids unnecessary loops. That makes it a functional choice for a Roku Ultra installed close to the screen.

Streaming and Gaming Feature Coverage

VRR, ALLM, QMS, SBTM, Dynamic HDR, and advanced audio support make the cable suitable for a mixed entertainment system. The connected devices determine which features become active in practice.

It supports 8K at 60Hz and 4K at 120Hz, making it a capable connection for a Roku Ultra even when the streaming box is positioned much farther from the television or projector than a standard six-foot cable allows.

Pros

• Long 15-foot installation length
• 48Gbps ultra-high-speed bandwidth
• Solid copper wire construction
• 24K gold-plated connectors
• Lifetime warranty included

Cons

• Longest cable may add cable clutter
• Premium pricing versus shorter alternatives

We may earn a commission when you buy through this link, at no additional cost to you.

Its premium feature is the combination of reach and stated construction. Solid copper wiring, 24K gold-plated connectors, and a bend-tested lifespan of more than 25,000 bends target dependable use. The listing supports HDR10+, HDCP 2.3, eARC, 3D, Ethernet, Dolby TrueHD 7.1, and hot plugging. Compatibility explicitly includes Roku devices, Apple TV, Xbox, PlayStation, Nintendo Switch, computers, Blu-ray players, monitors, and projectors.

A long cable is only a benefit when needed. In a compact setup, 15 feet can create unnecessary slack, while a wall-mounted display and a nearby media shelf may make several feet of extra reach very helpful. The product also costs more than many shorter alternatives, and a lifetime warranty is listed instead of the limited warranty shown with the Anker cable. Maximum 8K or 4K at 120Hz modes still depend on the connected source and display.

This is the preferred option for longer installations, such as a wall-mounted television above a fireplace, a projector positioned away from the streaming box, or a media cabinet placed to one side of the room. Choose it when routing flexibility and lifetime coverage justify the premium selection. For a standard nearby connection, a 4-foot, 5-foot, or 6.6-foot cable is likely easier to manage.

Reach for Awkward Entertainment Layouts

Fifteen feet provides meaningful placement flexibility when the Roku Ultra cannot sit directly beside the television. It reduces the need for extension products, which can add another connection point into the signal path.

Premium Connector and Warranty Package

Solid copper wiring, 24K gold-plated connectors, more than 25,000 stated bends, and a lifetime warranty distinguish the package. These are meaningful considerations for a permanently installed home-entertainment connection.

Buying Guide – How to Choose the Best HDMI Cable for Roku Ultra

For most Roku Ultra owners, the decisive factors are correct physical fit, reliable signal delivery, a practical cable length, and compatibility with the television or audio system. Advanced gaming specifications can add value when the same cable will serve a console or computer, but they do not need to be the only consideration.

Confirm the Connector and Device Compatibility

A Roku Ultra uses a standard HDMI connection, so the cable should terminate in a male HDMI connector on both ends and include a standard HDMI port for the television or other display. Several options in this guide explicitly name Roku Ultra, while others list Roku TV or the broader Roku family. That distinction is not a reason by itself to reject a product, but direct mention can make the intended use clearer to a first-time buyer.

It is also important to consider the complete connection path. If the Roku Ultra connects to a television and the television passes sound to a soundbar, each relevant connection and feature must be supported by the equipment. A cable can carry eARC, Dolby Atmos, or HDR signals, but it cannot make an older television or soundbar decode them.

Match Bandwidth to Your Display

A stated 48Gbps bandwidth provides the headroom associated with HDMI 2.1 ultra-high-speed cables. Every product in this guide advertises that figure and supports 8K at 60Hz, although actual output depends on the Roku Ultra and television. For a typical 4K television, a good HDMI 2.1 cable is more than adequate, while a 4K at 120Hz or 4K at 240Hz television may benefit from the full capability of the cable.

Readers should avoid choosing based on resolution alone. Color depth, HDR formats, audio return functions, and compression support all contribute to the overall bandwidth picture. Certification provides a stronger indication that the cable is designed around the complete HDMI 2.1 specification rather than only being marketed with a high resolution number.

Measure Before Choosing Length

Cable length should follow the layout of the entertainment center rather than an arbitrary preference. Four feet suits components placed immediately together, five feet offers a little more reach, and 6.6 feet is a common middle ground. A 15-foot cable makes sense when the Roku Ultra must remain near a game console, streaming device, or media shelf while the television is wall-mounted several feet away.

Measure the planned path and add enough slack to bend the cable without creating strain. A long cable that is barely long enough can pull against the connector, while an excessively long cable in a compact area can be awkward to conceal. Buyers should also consider whether the intended route crosses power cables or passes through tight furniture channels.

Prioritize Stable Signal Construction

The connector shell, pins, conductor, shielding, and outer jacket all contribute to durability and signal stability. Braided nylon is common among the listed cables and helps the outer jacket resist routine bending. Gold-plated or nickel-plated pins are used by some options, while aluminum alloy shells, carbon steel connectors, copper cores, ferrite beads, and shielding appear in different combinations.

A cable routed behind a television should have reinforced strain relief where it enters the connector, because most stress occurs near that point. Construction is especially important if the Roku Ultra is unplugged and moved regularly. Buyers who plan to route the cable through furniture or a wall should look for a flexible cable and allow adequate bend space at both ends.

Check HDMI Certification

Official HDMI certification offers a more comprehensive quality reference than a packaging claim alone. The UGREEN, Ubluker, Zeskit, and Anker products in this guide are described as certified or officially certified, while the Silkland listing provides a QR-code verification method. Certification indicates that the cable has been evaluated against HDMI requirements and can be particularly reassuring for buyers concerned about high-bandwidth performance.

Certification does not eliminate the need to check device compatibility. It also does not mean every source and display will operate at the cable's maximum resolution or refresh rate. The cable is one part of the chain, and the most advanced modes require appropriate source hardware, display capability, and sometimes compression support.

Evaluate Audio and HDR Features

A Roku Ultra is often connected to an entertainment system rather than used only with television speakers. eARC and ARC support can carry audio from a television to a soundbar or receiver, while Dolby Atmos, Dolby TrueHD, DTS:X, and Dolby Vision can improve the experience when supported across the entire setup. Dynamic HDR, HDR10+, and HDR10 are additional factors for viewers who care about contrast, brightness, and color.

The cable should support the relevant pathway without forcing buyers to compromise between audio and video features. Every advanced function remains dependent on compatible equipment and content. Checking these details before purchasing prevents the common mistake of buying a cable for a future feature while failing to check whether the current television or soundbar can use it.

Account for Gaming and Future Upgrades

Roku Ultra owners who also own a current gaming console or PC may want VRR, ALLM, 4K at 120Hz, or 4K at 144Hz support. The high-refresh modes in this guide require compatible hardware and displays, but choosing a cable with those capabilities prevents a later upgrade from being constrained by the existing connection.

A certified 48Gbps cable is a useful long-term target because it supports the complete high-bandwidth feature set advertised in this guide. The Roku Ultra itself may continue to operate at lower video modes, but the cable can remain in place when another source is introduced. This makes it a practical consideration for an entertainment center intended to last for years.

How to Use and Care for Your HDMI Cable for Roku Ultra

Begin by identifying the intended HDMI input on the television, projector, monitor, or soundbar system. Connect one end of the cable to the Roku Ultra and the other to the selected device. If a television is responsible for passing sound to a soundbar, follow the manufacturer’s eARC or ARC setup instructions, and make sure the correct television audio output is enabled.

After connecting the cable, power on the Roku Ultra and display, then select the matching HDMI input from the television or projector menu. If the picture appears but the resolution or refresh rate is wrong, review the display and Roku Ultra output settings. Features such as 4K at 120Hz, VRR, HDR, Dolby Vision, and eARC will only activate when the source, display, and any intermediary device all support them.

To care for the cable, hold the connector housing rather than pulling the wire when unplugging. Avoid sharp folds, especially near the connector, and do not place the cable beneath furniture wheels or along a path where it can be repeatedly stepped on. For a concealed installation, leave a gentle service loop and check the connection periodically, especially if the Roku Ultra or television is moved.
