Extending your HDMI signal beyond the typical cable limit is a common challenge for home theater enthusiasts, professional AV installers, and gamers alike. Whether you’re setting up a projector in a dedicated cinema room, running a video feed to a digital sign across a store, or simply connecting a PC in another part of the room, a standard HDMI cable often falls short. This is where a 4K HDMI extender over Ethernet becomes an essential piece of technology, using the structured wiring in your walls to bridge the gap.
These devices, often called baluns, convert the HDMI signal to travel over a single, inexpensive Cat5e, Cat6, or Cat7 Ethernet cable, allowing for clean, high-quality video and audio transmission over much greater distances. The market offers a wide array of options, from basic point-to-point extenders to complex multi-display systems. This roundup cuts through the noise to present the ten best 4K HDMI extenders over Ethernet, helping you find the perfect solution for your specific distance, resolution, and feature requirements.

Buying Guide: How to Choose the Best 4K HDMI Extender Over Ethernet
When I need to send a high-quality video signal a long way, I always look at a 4K HDMI extender over Ethernet. These little boxes are lifesavers for home theaters, conference rooms, and digital signage, letting you run HDMI over a simple network cable for much greater distances. But not all extenders are created equal. Here’s what I focus on when I’m picking one out.
First and foremost, I check the supported video resolution. You’re looking for a 4K HDMI extender over Ethernet, so make sure it explicitly states it supports 4K UHD and, ideally, a high refresh rate like 60Hz. This is non-negotiable for a sharp, smooth picture with modern gaming consoles, streaming devices, and Blu-ray players. Some older or cheaper models might only handle 1080p, which is a deal-breaker for a 4K setup. Also, look for HDR compatibility (like HDR10 or Dolby Vision) if you want those vibrant colors and high contrast ratios.
Next, I think about the audio. Most extenders will pass through common formats like Dolby Digital, but if you have a high-end sound system, you need to verify it supports the high-resolution audio you care about, such as Dolby TrueHD or DTS-HD Master Audio. Some models even have a separate optical audio output, which can be a nice bonus for connecting directly to a soundbar or AV receiver.
The maximum distance is a huge factor. The product will always list a maximum range, but remember that this is often a “best-case” number. The quality of your Ethernet cable matters a lot here. For runs over 50 meters, I always use Cat6 or even Cat6a cable to ensure a stable signal. Many units can work in pairs over a local network switch, which gives you incredible flexibility, but for the simplest point-to-point connection, just make sure the distance rating meets your needs.
Finally, I consider the little extras. Does it support HDCP 2.2? It must, otherwise, most 4K content from commercial sources will be blocked. Is it a one-way transmitter (for just sending a signal) or two-way (allowing for IR or serial control to operate the source device from the display location)? If you need to control a cable box from your couch in another room, two-way IR is a must-have feature. Power options are also worth a glance; some kits are powered only at the transmitter side, which is very convenient.
FAQ
What is the maximum distance for a 4K HDMI extender over Ethernet?
The distance can vary significantly between models, but a good rule of thumb is that most standard units can reliably transmit a 4K signal up to 100 meters (about 328 feet) using a high-quality Cat6 Ethernet cable. Some professional-grade models can push this even further. It’s important to check the specifications for the specific extender you’re considering, as the maximum resolution might decrease at the absolute limit of the range.
Can I use a network switch with my HDMI extender over Ethernet?
Yes, in many cases you can. Instead of using a single, long Ethernet cable running directly from the transmitter to the receiver, some extender kits are designed to work over your existing local area network (LAN). This means you can plug the transmitter and receiver into any ports on the same network switch. This is fantastic for complex installations. However, you must confirm this feature is supported by the product, as not all extenders are designed for this mode of operation.
Do I need special Ethernet cables for a 4K HDMI extender?
For the best performance, especially with 4K HDR content, I strongly recommend using at least Cat6 Ethernet cables. While Cat5e can sometimes work for shorter distances, Cat6 provides better shielding and higher bandwidth, which gives you a much more reliable connection and helps prevent signal dropouts or visual artifacts. For runs approaching the maximum 100-meter distance, investing in good cables is one of the most important things you can do.
Will this device work with my gaming console for 4K gaming?
To work well with a modern gaming console like a PlayStation 5 or Xbox Series X, the extender needs to support a few key things. First, it must handle 4K at 60Hz as a bare minimum, but for future-proofing, 4K 120Hz support is even better. Second, it should have a very low latency. Look for specifications that mention “zero latency” or “near-zero latency” to ensure your button presses aren’t delayed, which is crucial for gaming. A standard 4K HDMI extender over Ethernet that meets these criteria should work just fine.
Why is HDCP 2.2 compliance important?
HDCP 2.2 is a copyright protection protocol that all modern 4K content uses. If your extender is not compliant with HDCP 2.2, it will fail to “handshake” with your 4K Blu-ray player, streaming device, or cable box. This results in a blank screen or an error message, even if all your other equipment is correct. Any extender you buy today must be HDCP 2.2 compliant to work with protected 4K content.
Can I extend the audio separately from the video?
Many extenders offer this flexibility. They often include an optical (Toslink) audio output on the receiver unit, allowing you to send audio directly to a sound system while the video goes to the display. Some also support audio extraction, meaning you can pull the audio signal out and send it to a different destination than the video. Check the product’s input and output ports to see if it has the audio options you need for your specific setup.
