4K HDMI Extender Over Ethernet - Extend 4K up to 50m with PoC

In this review of the 4K HDMI Extender Over Ethernet, the bottom line is simple: it is a practical, no-nonsense solution for sending HDMI from a source to a remote display without running long HDMI cables. The reviewer found it best suited to installations where a single Cat5e/6 cable can bridge the gap and where 4K@30Hz or 1080p@60Hz video quality with YCbCr 4:4:4 is required. The unit's Power over Cable capability and an HDMI loopout on the transmitter are the single biggest practical advantages that make setup cleaner and reduce wall-wart clutter.

Key Features

• 4K and 1080p support: Handles up to 4K@30Hz with YCbCr 4:4:4 and 1080p@60Hz with YCbCr 4:4:4 so image quality is preserved for both UHD and full HD sources.
• Long-range extension: Extends 4K signals to about 164 ft (50 m) and 1080p signals to about 229 ft (70 m) over a single Cat5e/Cat6 cable, reducing the need for multiple runs or active repeaters.
• HDMI loopout: The transmitter includes an HDMI loopout port so a local display can be connected without interrupting the remote feed.
• Power over Cable (PoC): The receiver can be powered by the transmitter over the Ethernet cable, simplifying power management at the remote end.
• Smart EDID management: Built-in EDID handling helps the source negotiate compatible resolutions for reliable playback across mixed displays.
• Bidirectional IR passthrough: IR signals can travel both ways so remote control of source equipment is possible from the display location.

Who It's For

This extender is aimed at installers, home theater enthusiasts, and AV integrators who need to place a display away from a source without running long HDMI cable runs. It is especially useful in homes, classrooms, and conference rooms where a single Cat5e or Cat6 conduit is available and where 4K@30Hz or quality 1080p is acceptable.

Those who need 4K@60Hz, HDR support, or the latest HDMI 2.x features should look elsewhere, as this product follows HDMI 1.4 and HDCP 1.4 specifications and is optimized for the 4K@30Hz performance it describes.

Pros & Cons

Pros

• Supports 4K@30Hz and 1080p@60Hz with YCbCr 4:4:4 for strong image fidelity in typical AV setups.
• PoC feature reduces the need for a separate power supply at the receiver, simplifying installs.
• Transmitter HDMI loopout and bidirectional IR passthrough add valuable flexibility for local monitoring and remote control.

Cons

• Limited to HDMI 1.4/HDCP 1.4 feature set, so it will not support 4K@60Hz or newer HDR formats.

Specifications

Our Verdict

The 4K HDMI Extender Over Ethernet is a sensible, cost-effective choice for anyone who needs to place a display tens of meters from a source using existing Cat5e/6 wiring. It delivers reliable 4K@30Hz and excellent 1080p performance, plus practical features like PoC and an HDMI loopout that make installation cleaner. Choose this for straightforward AV extension needs; seek newer HDMI 2.x extenders if you need 4K@60Hz or HDR support.

Frequently Asked Questions
