UGREEN HDMI OVER ETHERNET EXTENDER 1080P 70M EU

The UGREEN HDMI Over Ethernet Extender 1080P 70M (model CM455, part number 20519EU) solves a very specific problem: how to send a high-definition video signal across a long distance without losing quality. Standard HDMI cables struggle beyond a few meters. Therefore, this device converts the HDMI signal into a network signal. Then it sends that signal over a standard Ethernet cable. Finally, the receiver converts the signal back to HDMI at the destination. Consequently, you can place your source device and your display up to 70 meters apart.https://sammertechnology.co.ke/

 What You Get in the Box

UGREEN packages this extender as a complete kit. You do not need to buy separate components. The box contains the following items:

• One Transmitter Unit (TX): This connects to your video source device.

• One Receiver Unit (RX): This connects to your display device.

• Two Power Adapters: Each unit requires its own 5V/1A power supply.

• IR Extension Cables: These allow you to control your source device from the display location.

• User Manual: A quick guide for setup.

 How It Works

This extender uses a simple three-step process. First, you connect the transmitter to your source. Next, you run a single Ethernet cable between the two units. Finally, you connect the receiver to your display. The system handles the conversion automatically.

The Transmission Path:

1. Source: Connect a PC, laptop, media player, or game console to the transmitter’s HDMI input.

2. Transport: Connect a single Cat5e or Cat6 Ethernet cable to the transmitter’s RJ45 port. Then connect the other end to the receiver’s RJ45 port.

3. Display: Connect the receiver’s HDMI output to a TV, monitor, or projector.

The units use EDID management to automatically detect the display’s capabilities. Therefore, the source device outputs the best possible resolution and format. Additionally, EQ (Equalization) technology adjusts the signal strength to compensate for the cable length. This ensures a stable picture even at the maximum distance.

Video and Audio Performance

The CM455 prioritizes reliability over raw specifications. It supports 1080p resolution at 60Hz. This means you get a sharp, smooth Full HD picture. The extender also supports 3D video and Deep Color. However, this model does not support 4K resolution at the full 70-meter distance.

The audio performance is impressive. The extender passes through high-quality surround sound formats. You can enjoy Dolby Digital, DTS, and DSD audio. Furthermore, it supports 5.1 and 7.1 channel surround sound systems. The digital audio sampling rate reaches 192KHz at 24-bit. Consequently, the sound quality matches the high-definition video.

 IR Remote Control Extension

A standout feature is the bi-directional IR control. This means you can control your source device from the display location. Imagine your cable box is in a closet. Your TV is across the room. You can point your remote at the TV. The receiver captures the IR signal. Then it sends that signal back through the Ethernet cable to the transmitter. Finally, the transmitter blasts the IR signal at your cable box. Therefore, you do not need to walk to the closet to change the channel.

 Design and Durability

UGREEN builds the CM455 with a durable aluminum housing. Aluminum helps dissipate heat. As a result, the units can run continuously without overheating. This is important for permanent installations. The compact size (74 x 26 x 56 mm) allows for easy mounting behind a TV or in an equipment rack.

The units include LED indicators for power and link status. You can quickly verify that the system is working. The plug-and-play design means you do not need to install drivers or software. It works with Windows, macOS, and Linux operating systems.

 Ideal Use Cases

This extender excels in professional and home environments.

Conference Rooms: Keep the presentation PC in a secure cabinet. Then display the video on a projector across the room. The IR extension lets you control the PC from the podium.

Digital Signage: Place the media player in a central closet. Then distribute the signal to multiple displays in different areas. The long-distance capability reduces the need for multiple players.

Home Theater: Put all your AV equipment in a closet or rack. Then run a single Ethernet cable to your TV. This creates a clean, wire-free look in your living room.

Security Monitoring: Connect a DVR or NVR to a monitor in a different room or building. The stable transmission ensures you see a clear picture without lag.https://www.ryans.com/ugreen-cm455-20519eu-hdmi-female-to-rj45-female-hdmi-extender

 Limitations to Consider

The ugreen CM455 is a specialized tool. It has specific limitations.

Resolution Cap: The primary limitation is 1080p at 70 meters. If you need 4K video over a long distance, this model is not suitable. You would need a more advanced (and more expensive) extender that supports 4K over Ethernet.

Power Requirement: Both the transmitter and receiver require a 5V/1A power adapter. You need a power outlet at both the source location and the display location. This adds a small amount of setup complexity compared to a passive HDMI cable.

Ethernet Cable Quality: The system requires a Cat5e or Cat6 cable for the full 70-meter distance. A lower-quality cable might reduce the maximum distance or cause signal dropouts. Therefore, use a good quality cable for best results.

📊 Key Technical Specifications

 Final Thoughts

The UGREEN CM455 HDMI Over Ethernet Extender is a reliable solution for a specific need. It solves the problem of sending a Full HD signal across a distance where a normal HDMI cable would fail. The setup is straightforward. The aluminum build is durable. The audio support is excellent. Furthermore, the IR control extension adds significant convenience.

However, it is not a universal solution. It maxes out at 1080p. It requires power at both ends. Therefore, you should only buy it if your needs match its capabilities. If you need to send a 1080p signal across 50 or 70 meters, this extender will do the job perfectly. It is a professional-grade tool for conference rooms, digital signage, and advanced home theater systems.
