Product Features

Long-Distance HDMI Transmission Over Ethernet

Extends HDMI signals up to 70 metres over Cat5e/Cat6 cable, far beyond the typical limits of standard HDMI leads, making it well suited for larger spaces where displays are remote from the source.

High-Definition Video Support

Delivers stable, crisp video and audio for most HDMI sources and displays — commonly supporting 1080p Full HD resolution and often compatible with higher resolutions up to 4K (depending on display, source, and cable quality).

Easy, Cost-Effective Cabling

Utilizes standard Ethernet CAT-series cables (Cat5e, Cat6, or Cat7), reducing cost and complexity compared with running long runs of heavy HDMI cable.

Plug-and-Play Setup

No drivers or specialized software are needed — simply connect the HDMI source to the transmitter, use Ethernet to link to the receiver, and connect your display for instant video extension.

Broad Device Compatibility

Compatible with a wide range of HDMI-equipped devices such as laptops, desktops, PCs, media players, set-top boxes, gaming consoles, and streaming devices, paired with HDMI displays such as monitors, TVs, and projectors.

Ideal for Multiple Applications

Perfect for office presentations, digital signage, training rooms, auditoriums, trade shows, home theater layouts, or any situation where long-distance HDMI connectivity is required without compromising picture quality.
