Running an HDMI cable across a long distance can be a frustrating challenge. Standard HDMI cables lose signal integrity after about 50 feet (15 meters), leading to flickering screens, poor resolution, or no picture at all. Whether you’re setting up a home theater, a conference room display, or digital signage, you need a reliable solution. Fortunately, there’s a professional-grade method that is both effective and affordable: sending your HDMI signal over a standard Ethernet cable.
At D-Lay Cable, with over 20 years of expertise in manufacturing high-performance connectivity solutions, we’ve helped countless clients overcome this exact problem. dlaycable will walk you through everything you need to know about installing an HDMI over Ethernet system, ensuring a crystal-clear picture every time.

Why Use HDMI Over Ethernet? The Key Advantages
Before we dive into the “how,” let’s understand the “why.” Using an HDMI extender with Ethernet cabling is the preferred method for professionals for several key reasons:
- Extended Distance: While a standard HDMI cable maxes out around 50 feet, a quality Cat6 cable can carry a 1080p HDMI signal up to 200 feet (60 meters) and even a 4K signal up to 100 feet (30 meters) or more, depending on the extender kit.
- Cost-Effectiveness: A long, high-quality fiber optic HDMI cable is significantly more expensive than an equivalent length of premium Ethernet cable from a trusted supplier like D-Lay Cable.
- Flexibility & Pre-existing Wiring: Many modern homes and offices are already wired with Cat5e or Cat6 Ethernet cables. This solution allows you to leverage that existing infrastructure without running new, bulky HDMI cables through walls. Ethernet cables are also thinner and more flexible, making them easier to route.
- Signal Integrity: HDMI extenders are active devices. They convert the HDMI signal to a format suitable for transmission over twisted-pair Ethernet, then convert it back at the other end. This process maintains a strong, clear, and uncompressed signal, free from the degradation that plagues long passive cables.
Your Pre-Installation Checklist: What You’ll Need
Gathering the right components is the first step to success. Quality matters at every point in the chain. Here’s your essential checklist:
- An HDMI Source: This could be a Blu-ray player, gaming console (PS5, Xbox), computer, or media streamer (Apple TV, Roku).
- An HDMI Display: Your TV, projector, or computer monitor.
- An HDMI Over Ethernet Extender Kit: This kit includes two main components:
- A Transmitter (TX): Connects to your HDMI source.
- A Receiver (RX): Connects to your HDMI display.
Most kits also include power adapters for one or both units.
- Two Short HDMI Cables: You’ll need one to connect the source to the transmitter and another to connect the receiver to the display.
- A High-Performance Ethernet Cable: This is the crucial link. For best results, we strongly recommend a D-Lay Cable Cat6 or Cat6a Ethernet Cable of the required length. The quality of this cable directly impacts the maximum distance and resolution you can achieve.
Step-by-Step Installation: From Box to Picture-Perfect Display
The installation process is surprisingly straightforward. Follow these steps carefully for a seamless setup.
Step 1: Connect the Transmitter (TX) to Your Source
Take the Transmitter unit (often labeled “TX” or “Sender”). Using one of your short HDMI cables, connect the HDMI output port of your source device (e.g., your Blu-ray player) to the HDMI input port on the Transmitter.
Step 2: Connect the Receiver (RX) to Your Display
Now, take the Receiver unit (labeled “RX” or “Receiver”). Using your other short HDMI cable, connect the HDMI output port on the Receiver to an available HDMI input port on your TV or projector.
Step 3: Run the Ethernet Cable
This is the long-distance connection. Plug one end of your D-Lay Cable Cat6 Ethernet cable into the Ethernet port on the Transmitter (TX). Run the cable to your display’s location and plug the other end into the Ethernet port on the Receiver (RX). Ensure the plugs click securely into place.
Step 4: Connect the Power
Most HDMI extenders require power to boost the signal. Plug the included power adapters into the DC power jacks on both the Transmitter and Receiver units, and then into a wall outlet or power strip. Some models may only require power on one end (often called PoC – Power over Cable). Check your kit’s manual.
Step 5: Power On and Test
Power on your source device and your display. Switch the display to the correct HDMI input you connected the Receiver to. You should now see a perfect picture from your source device. Congratulations, you’ve successfully extended your HDMI signal!
Choosing the Right Ethernet Cable: A D-Lay Cable Insight
The “weakest link” in this setup is often a low-quality Ethernet cable. As a leading cable manufacturer, we know that not all cables are created equal. Here’s what you need to know:
- Cat5e: The minimum requirement. It can handle 1080p signals over shorter distances but may struggle with 4K content or longer runs. It is more susceptible to signal interference (crosstalk).
- Cat6: The D-Lay Cable Recommendation. Cat6 features more tightly twisted pairs and a central spline to reduce crosstalk. This robust construction ensures a more stable signal, making it ideal for 1080p and 4K UHD over longer distances. It’s the sweet spot for performance and value.
- Cat6a/Cat7: These offer even better shielding and performance, essential for 4K HDR content at 60Hz or in environments with high electromagnetic interference (EMI).
At D-Lay Cable, our Ethernet cables are manufactured with 100% pure copper conductors and undergo rigorous quality control. This guarantees maximum signal conductivity and reliability, unlike cheaper Copper Clad Aluminum (CCA) cables which fail over long distances and are not compliant with TIA standards. Investing in a quality cable is investing in a clear picture.
Pro-Tips & Common Troubleshooting
Running into issues? Here are some expert tips from our team:
- No Picture? Double-check all connections. Ensure both the transmitter and receiver have power (look for an indicator light). Make sure your TV is on the correct HDMI input.
- Flickering or “Sparkles”? This usually indicates signal degradation. Your Ethernet cable might be too long for the resolution you’re sending, or it might be a lower-quality (CCA) cable. Try a shorter, higher-quality Cat6 cable. Also, ensure the cable isn’t tightly coiled or running parallel to high-voltage power lines.
- Can I use a switch or router in between? Generally, no. Most standard HDMI extenders require a direct, point-to-point connection. Do not plug them into your home’s network switch or router unless you have a specialized “HDMI over IP” extender designed for that purpose.
- Solid vs. Stranded Core: For runs inside walls, a solid-core Ethernet cable is best. For shorter, flexible patch connections, stranded-core is fine. D-Lay Cable offers both types to meet your specific project needs.
