The extender sends uncompressed 4K at 60Hz in YUV 4:4:4 over a single Cat 6, 6A, or 7 cable for distances advertised up to 230 feet, or approximately 70 meters. HDR10+, Dolby Digital, HLG, and high-fidelity audio support broaden its appeal, while zero-latency transfer helps it fit naturally into gaming, media, and presentation installations. PoC means only the transmitter needs a power connection, reducing wiring at a difficult-to-reach receiver location.

The trade-offs are modest but worth considering. The IR path is one-way rather than bidirectional, so remote-control direction should be confirmed before installation. Cat 6A or Cat 7 is listed among the supported cable types, and the strongest long-run performance depends on a properly terminated high-quality cable. The compact metal housing also helps with durability and heat dissipation, but it does not eliminate the importance of cable quality.

This is the most versatile selection for a buyer who wants true 4K60, HDR, long reach, and PoC without moving into a specialized HDBaseT installation. It suits anyone extending a Blu-ray player, game console, media player, satellite box, PC, or laptop to a wall-mounted television or projector. For most buyers seeking one capable general-purpose extender, it provides the strongest feature balance.

4K60 and HDR Performance

The headline HDMI 2.0a and 18Gbps specification enables 4K at 60Hz with YUV 4:4:4 rather than the more restrictive chroma-subsampled formats found on many lower-bandwidth units. HDR10+, HLG, Dolby Digital, and HDCP 2.2 support further improve compatibility with current source devices and modern displays.

Clean Installation with PoC

Power over Cable eliminates the need for a separate power adapter at the receiver end. The included transmitter, receiver, IR components, power supply, and manual create a more complete installation package, making the kit practical for rooms where only one convenient outlet is available.

It carries uncompressed 4K at 60Hz RGB or YCbCr 4:4:4 video and audio over one Cat 6 or 7 cable for up to 165 feet. The specification includes 18Gbps bandwidth, HDR, HDMI 2.1, HDCP 2.2, and up to 12-bit color. The transmitter's loop-out can connect a local screen while the receiver carries the main signal elsewhere, and built-in EDID management helps align source and display resolution behavior.

One-way IR passthrough lets users operate a streaming device, media player, or cable box from the receiver location, although it does not provide the bidirectional control offered by some alternatives. The kit must use a direct Cat 6 or 7 connection and cannot be inserted into a router or network switch. These are meaningful constraints, but they are predictable and manageable in a planned point-to-point installation.

Choose this model when the installation needs a local confidence monitor, 4K60 color quality, and IR control from the remote endpoint. It works well for wall-mounted displays, hidden AV racks, digital signage, conference rooms, and home theaters. Buyers who need much longer reach should consider the OREI HDBaseT model, while those without a local display can focus on simpler extenders.

Local Loop-Out Monitoring

The transmitter-side loop output allows an installer or operator to view the source on a nearby monitor while the same content travels to the remote display. This is valuable for troubleshooting, presentation confidence displays, and installations where local control is part of the room design.

High-Quality 4K Transmission

Support for 18Gbps bandwidth, 4K60 4:4:4, 12-bit color, HDR, and HDCP 2.2 places this extender above basic 1080p or 4K30 models. It also supports LPCM, Dolby Digital, Dolby TrueHD, DTS-HD, and DSD audio formats for a more complete home-theater signal path.

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

Video support includes HDMI 2.0a, HDCP 2.2, UHD 4K at 60Hz, 2K at 60Hz YUV 4:4:4, HDR, HDR10+, Dolby Vision, and 18Gbps bandwidth. Audio support includes DTS-HD, Dolby TrueHD, and 7.1-channel digital audio. Bi-directional IR lets the remote display's control signals reach the source, while RS-232 provides another integration path for compatible control systems.

This extender is less interchangeable than many simpler baluns. OREI states that its HDBaseT transmitter and receiver must be the matching pair and are not compatible with other OREI HDBaseT models or devices from other brands because of chipset differences. That limitation makes careful planning essential, particularly for installers maintaining multiple equipment types. PoC also simplifies deployment by allowing one power adapter at either endpoint.

It is best suited to large commercial spaces, conference systems, digital-signage networks, projection installations, and homes with exceptionally long in-wall runs. The included manual, sender, receiver, PoC power supply, IR kit, and mounting ears support a professional installation. When the stated 400-foot reach and advanced control features matter, this is the premium pick.

Extended HDBaseT Reach

HDBaseT is designed to carry high-bandwidth AV over structured cabling over longer distances than ordinary point-to-point extenders typically specify. The advertised 400-foot capability makes this model useful when the display is at the far end of a large building, campus room, or auditorium.

Professional Control Options

Two-way IR, RS-232, and CEC provide several methods for controlling source equipment and integrating the extender into a larger system. These features distinguish it from basic HDMI baluns intended only for video and audio transport across one room.

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

The listed formats include 4K at 30Hz, 1080p, 720p, 576p, and 480p. Its product information clearly distinguishes this unit from a 4K60 extender, so buyers should not expect the same gaming-level refresh rate or 4:4:4 output as the higher-bandwidth OREI options. The transmitter can provide a local display output while the main signal reaches a remote screen.

PoC reduces the number of required power connections, and the package includes an HDMI transmitter, receiver, IR transmitter and receiver cables, a 12V 1A adapter, and a manual. One-year warranty coverage adds reassurance. However, this is an HDMI transmission product rather than an IP extender, and it is expressly not compatible with HDMI ARC or network-based systems.

This model is well suited to a living room, conference room, classroom, or surveillance-style display installation that needs 4K30 but does not need 4K60 gaming performance. Its combination of a high rating, flexible resolution support, local monitoring, and PoC makes it a practical choice for established structured-cabling projects.

Flexible Resolution Support

Supporting everything from 4K30 down to standard-definition formats makes the extender usable with a broad range of source and display equipment. It is particularly appropriate when the destination screen or source device does not require a 60Hz 4K workflow.

Point-to-Point Signal Design

The kit is explicitly a direct HDMI-over-cable system rather than a network streamer. Keeping that distinction in mind helps prevent installation mistakes and makes the unit appropriate for integrators who need predictable dedicated signal paths.

Cons

• Not positioned for 4K60
• Power adapter not included

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

The system transmits uncompressed Full HD 1080p at 60Hz with 3D support over one Ethernet cable for up to 196 feet, or 60 meters. High-grade solid-copper Cat 6 or Cat 7 is recommended for best results, while Cat 5e compatibility broadens the possible applications. Smart EDID copying is designed to improve source-to-display matching and reduce common no-signal issues.

PoC allows the kit to be powered from one end, and the included USB-A-to-DC lead can draw power from a TV, computer, or common USB wall charger. A separate power adapter is not included, which is an important distinction for buyers creating a complete installation kit. The aluminum alloy housing and ventilation design support durability and heat dissipation.

This is a strong recommendation for anyone who needs reliable 1080p rather than 4K60. Its high rating, EDID behavior, and single-power arrangement reduce both technical and installation friction. Consumers should verify that a suitable USB power source is available at the chosen endpoint and should use solid-copper Cat 6 or Cat 7 for the longest runs.

Smart EDID Improves Recognition

The EDID copy function reads display parameters and helps the source negotiate a suitable output. That can be especially helpful when a computer, media player, or streaming device does not automatically identify the extended display correctly.

Convenient Single-Power Operation

PoC removes the need for a second power supply at the display end. The included USB-A-to-DC cable offers flexibility, though the absence of a conventional power adapter means buyers may need to source a USB charger if neither endpoint can supply suitable power.

Pros

• Extended 70-meter reach
• Receiver-side HDMI output
• Transmitter-side loop output
• Automatic cable adjustment
• No driver installation

Cons

• Limited to 1080p60
• Distance depends on cable grade

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

For Full HD 1080p at 60Hz with 3D support, the listed distance is up to 164 feet or 50 meters over Cat 5e or Cat 6, and up to 230 feet or 70 meters over Cat 6a or Cat 7. The zero-loss transmission description, audio support for DTS-HD and Dolby TrueHD, and audio-video synchronization make it suitable for home entertainment and commercial display applications.

The output flexibility deserves particular attention. An HDMI output at the receiver can support a one-input, two-output arrangement, while the transmitter loop-out can create a one-input, three-output setup. This is useful when the same source needs to feed more than one screen, though each destination still requires an appropriate connection. The EQ button provides automatic adjustment for cable length.

The kit is a good general choice for offices, classrooms, gyms, bars, meeting rooms, and home theaters that primarily use Full HD. IR passthrough allows operation of a source from the receiver area, while PoC means only the transmitter requires the included style of power connection. It lacks 4K60 capability, so high-refresh gaming and high-bandwidth 4K installations should look elsewhere.

Flexible Multi-Display Outputs

Both the receiver output and transmitter loop-out create options beyond a simple one-screen extension. The arrangement can support local monitoring, secondary displays, or installations where more than one screen needs the same source.

Automatic Length Adjustment

The built-in EQ function is designed to tune the extender for the cable run. Correct adjustment and a suitable Cat 6a or Cat 7 cable are important when maximizing the advertised distance of up to 230 feet.

The stated distance depends on resolution. A 4K signal can extend up to 164 feet or 50 meters, while 1080p can travel as far as 229 feet or 70 meters over one Ethernet cable. Compliance with HDMI 1.4 and HDCP 1.4 places it firmly in the 4K30 class, even though 4K at 60Hz is not listed. Smart EDID helps simplify source-to-display negotiation.

Bidirectional IR is a significant advantage over the one-way models in this roundup because it allows remote-control signals to travel more flexibly between the source and display areas. PoC powers the receiver through the Ethernet cable, and the loop-out provides a local display connection for monitoring or dual-display use. The older specification means buyers should assess it as a 4K30 solution rather than a gaming-grade 4K60 option.

This is an attractive choice for home theaters, conference rooms, offices, schools, and any installation that prioritizes 1080p reach and user-friendly control while still supporting 4K content at 30Hz. Its 5.0 rating, broad cable support, and useful feature set make it one of the most balanced choices, although modern 4K60 demands call for a higher-bandwidth alternative.

Resolution-Aware Distance

The extender maintains up to 50 meters for 4K and up to 70 meters for 1080p. Recognizing that high-resolution signals consume more bandwidth helps prevent a buyer from expecting identical reach at every output format.

The extender carries 4K Ultra HD at 60Hz with 4:4:4 color over standard Cat 5e, Cat 6, or Cat 7 cable for up to 200 feet, or 60 meters. Its loop-out allows local monitoring while the main signal travels to the remote receiver, and PoC means the display end does not require a separate power outlet. That is particularly useful for ceiling-mounted projectors and digital-signage displays.

The package includes one HDMI transmitter, one HDMI receiver, a 12V 1A power adapter, and a product manual. The listed specification does not include IR passthrough, RS-232, or bidirectional CEC, so this model is less attractive for installations where remote source control or command integration is essential. It remains a clean option for extending video and power without complex control features.

Buyers should choose this kit when the primary requirements are 4K60, HDR10, a long cable run, and straightforward point-to-point operation. It fits home theaters, conference rooms, professional AV installations, and display environments where a loop-out is useful. Installers needing remote-control passthrough should instead examine the OREI models with IR support.

Uncompressed 4K60 Video

Supporting 4:4:4 color at 60Hz preserves finer detail than chroma-subsampled 4K modes. This is a meaningful advantage for a living-room television, presentation screen, or professional display when the source and cable installation can support the full signal.

Simple Power and Monitoring

PoC reduces the receiver-end wiring, while the loop-out lets technicians or operators watch the source locally. These practical features are particularly helpful in ceiling and wall installations where access is limited.

The system converts the HDMI signal to standard TCP/IP for transmission over internet-style cabling. It supports 1080p, 3D, HDCP, Dolby TrueHD, and DTS Master Audio, while the listed color depth reaches 36 bits with Cat 7 and 24 bits with Cat 6. An M-JPEG processing technique is described as providing compression without image-quality loss.

IR extension functionality lets users control source devices remotely, which is valuable when the source is located in an equipment closet or technical area. Because its distance and color-depth characteristics depend on cable type, selecting the appropriate structured cable is critical. The product information also mentions tablets among compatible devices, while the primary use remains dedicated Full HD AV transmission.

This model is best for installers who prioritize maximum reach and TCP/IP-based transport over modern 4K capabilities. It can suit large homes, schools, offices, retail spaces, or long corridor installations that require remote-control access. It is not the right choice for 4K60 content, and buyers should verify exact source, display, and control compatibility before finalizing the installation.

Maximum Cable Reach

The stated 120-meter capability gives this extender an advantage for installations that cannot be served by a typical room-length balun. Structured-cable quality and the selected category become increasingly important as the run approaches the advertised limit.

Remote Source Control

IR extension supports control of devices located away from the display. This is especially useful where the source sits in a rack, closet, or reception area and the user needs to operate it from the viewing location.

Buying Guide – How to Choose the Best HDMI Extender Cat 5 6 7 Ethernet

Choosing an HDMI extender requires matching bandwidth, cable distance, power, control, and EDID behavior to the source, display, and installation environment. The most important distinction is whether the application needs 1080p, 4K30, or 4K60, because advertised cable reach can vary with resolution.

Resolution and Refresh Rate

Resolution and refresh rate determine how much signal bandwidth the extender must carry. A 1080p-at-60Hz system has different capabilities from a 4K30 model or a 4K60 extender supporting 4:4:4 color and HDR. Check both the source output and display input, because the extender cannot create a higher refresh rate than the source supplies or a higher resolution than the display accepts.

Maximum Cable Distance

Maximum distance figures should be read as model- and resolution-specific limits. Some products reach approximately 230 feet for 1080p on Cat 6a or Cat 7, while others advertise 200 feet, 196 feet, 165 feet, or 400 feet under particular conditions. Higher resolutions usually reduce usable reach, and Cat 5e generally supports a shorter maximum than Cat 6 or Cat 7.

Cable Category and Installation Quality

All ten products are designed around Cat 5e, Cat 6, or Cat 7-style Ethernet cabling, but advertised reach improves with higher-grade cable. Solid-copper Cat 6 or Cat 7 is specifically recommended for stronger performance in several descriptions. Proper termination, avoiding excessive splices, and keeping signal cables away from interference sources can be as important as the category label.

Power Over Cable

PoC sends power through the Ethernet cable so only one endpoint needs a power source. It is especially useful for ceiling projectors, lobby displays, and wall-mounted televisions where installing a second outlet is inconvenient. Check which endpoint requires power, what adapter is included, and whether the model can also be powered through a USB connection.

IR and Control Options

IR passthrough allows a source device to be controlled from the remote display area, which is essential when the source is hidden in a cabinet or rack. One-way IR supports control from the receiver side, bidirectional IR offers more flexibility, and models with RS-232 suit professional control systems. If no control path is needed, a simpler unit may be sufficient.

EDID and Loop-Out Support

EDID management helps a source recognize the extended display's capabilities and negotiate a compatible mode, reducing blank screens and resolution mismatches. An HDMI loop-out permits local monitoring or a second display at the transmitter side. These features are valuable in dual-display, troubleshooting, presentation, and professional AV installations where a completely hidden source still needs visual confirmation.

Audio, HDR, and IP Functionality

HDR support and high-bandwidth color modes can improve the image on compatible displays, while advanced audio formats such as Dolby TrueHD, DTS-HD, and DSD support matter for home theaters. Some extenders use TCP/IP internally, but most remain dedicated point-to-point AV systems and cannot be placed on a network switch. Verify HDMI ARC, CEC, audio, and IP claims separately.

How to Use and Care for Your HDMI Extender Cat 5 6 7 Ethernet

Begin by identifying the source, the remote display, and any nearby display that needs a loop-out. Connect the source to the HDMI input on the transmitter, then connect the transmitter and receiver with a continuous run of properly terminated Ethernet cable. Keep the run within the distance and resolution limits published for the selected model, and avoid unnecessary couplers or signal converters.

Power the system according to its PoC arrangement. With a conventional PoC extender, connect the supplied power adapter at the transmitter; with a USB-powered model, connect the specified USB cable to the approved endpoint or a suitable USB power source. Connect the receiver to the display, install the IR emitter and receiver where they can communicate with the source remote, and configure EDID or loop-out functions as required by the installation.
