Znoogrn 4K HDMI to RJ45 Extender
The Znoogrn kit uses a transmitter (TX) and receiver (RX) to send HDMI signals over CAT 5/6 cables, replacing long HDMI runs with ethernet cables. It supports 3D and high-definition resolutions up to 1080p, with a path to 4K signals depending on source compatibility. The system is designed to extend both video and audio up to 30 meters (98 feet). Note that HDCP is not supported, which can impact protected content in some setups. Pairing is required, so consistently using matching TX and RX units is essential for reliable operation.
Wiistar HDMI Extender Over Cat5e/6
Wiistar’s extender emphasizes long-distance HDMI delivery via Cat5e or Cat6, achieving up to 60 meters (196 feet). It transmits both video and audio concurrently, with performance claims of 1080p resolution and high-speed, point-to-point output. The TX/RX pair is compact (cable length around 22 cm) and designed for easy setup: connect TX to the source, RX to the display, and run a power supply to both ends. Users should ensure the network cables are of high quality since inferior cables can reduce distance or picture quality.
Steetek HDMI Extender 1080p
Steetek provides a reliable full HD 1080p HDMI extender over Cat5e/6/7, with a maximum suggested distance around 164 feet (50 meters). It supports 3D and includes an EDID copy function to help the receiver adapt to various displays. A notable feature is Power over Cable (POC), which allows the transmitter and receiver to share power from one source, simplifying installation. The product emphasizes being compatible with HDMI 1.3 devices and advises using higher-grade Ethernet cables for the best results.
OREI 4K HDMI over Ethernet Extender
OREI’s EX-170C model extends 4K HDMI and Full HD 1080p signals over CAT 6/7 up to 164 feet (50 meters) with attention to reliable transmission. It includes a loop-out on the transmitter for a local display and employs MJPEG compression to preserve efficiency at 4K resolutions. The kit ships with a dual-voltage setup and includes an international adapter, making it suitable for varying regional power requirements. This option suits home theaters or conference rooms seeking a clean, cord-efficient solution.
HDMI Over Ethernet Cat5e/6 (HDSUNWSTD)
HDSUNWSTD presents a bidirectional HDMI to Ethernet extender pair that supports full 1080p transmission over Cat5e/Cat6. The setup emphasizes ease of use with a plug-and-play approach and a robust physical interface, enabling reliable long-distance streaming between displays and source devices. The design claims improved audio and video synchronization across the network, making it a practical option for living rooms or classrooms where flexible display placement is important.
Buying Guide: key considerations when choosing an Ethernet to HDMI extender
Distance and resolution: Consider the maximum transmission distance you truly need. Many models support 1080p, while some advertise 4K compatibility at shorter distances. If you require 4K, verify the accepted frame rates and ensure the source and display support the same HDMI version and color space.
Cable quality and standard: Cat5e versus Cat6/7 can influence distance and signal integrity. Higher-grade cables reduce jitter and degradation over long runs. For longer installations, consider shielded cables and properly terminated connectors to maintain signal quality.
Power requirements: Some extenders use Power over Cable (POC) to simplify installation, while others require external power supplies for the TX, RX, or both. If you’re wiring behind walls or ceilings, POC can reduce clutter.
HDCP compatibility: Some extenders do not support HDCP-protected content. If your setup includes Blu-ray players, streaming devices, or certain gaming consoles that require HDCP, verify compatibility before purchase.
EDID handling: EDID copy or management helps the extender negotiate display parameters with the source, improving compatibility in multi-display environments or with unfamiliar displays. If you have unique monitors, an EDID-aware model is advantageous.
Bi-directional vs. uni-directional: Some devices allow two-way signaling between devices, while others are strictly TX-to-RX. For setups where you need to send a signal back to the source (for control or monitoring), ensure the model supports bidirectional transmission.
Installation and mounting: Look for compact TX/RX units, clear labeling, and simple plug-and-play design. A short TX/RX cable length around 20–25 cm can aid adaptability in tight spaces, but longer cables may be necessary for some installations.
Reliability features: Surge protection, robust housings, and manufacturer support can influence long-term performance. If your environment has power fluctuations or network interference, prioritize models with protective features.
In summary, the best Ethernet to HDMI extenders balance distance, resolution, and ease of use. Depending on your space, you may prioritize 4K capability with shorter runs or opt for longer-range 1080p extensions with robust EDID handling and simple installation. When choosing, align the product’s TX/RX pairing, cable quality, and power strategy with your specific theater, classroom, or office needs.
