UGREEN CM586 Wireless HDMI Extender – Detailed Overview

The UGREEN CM586 Wireless HDMI Extender (Model 90909) delivers reliable Full HD audio and video transmission without the need for long HDMI cables. Designed for modern homes, offices, and digital signage setups, it ensures easy setup and a clutter-free viewing experience. Ideal for users looking to buy wireless HDMI extenders in Kenya, this device provides professional-grade performance at an affordable price, now available at Passcode East Africa Techverse Limited.

Wireless Transmission and Range

The CM586 extends HDMI signals up to 50 meters (164 feet) in open space using advanced 5GHz frequency bands. This reduces interference and provides a stable, smooth connection. While walls or large obstacles may slightly reduce range, it still offers excellent transmission reliability for typical room-to-room setups.

Video and Audio Performance

With support for Full HD 1080p @60Hz, users experience sharp, lag-free visuals perfect for streaming, office presentations, and digital signage. It uses H.264 compression to maintain video integrity while optimizing bandwidth usage.
Audio compatibility includes PCM stereo, ensuring clear and consistent sound. While formats like Dolby Digital or DTS may not be supported, the performance remains strong for general entertainment and professional needs.

Local HDMI Loop-Out Functionality

A standout feature is the HDMI loop-out port on the transmitter, allowing users to connect a local display. This is ideal for scenarios such as classrooms, conferences, or live events where both presenter and audience need to view the same content simultaneously.

Low Latency for Real-Time Viewing

The system provides latency of under 200ms, which is excellent for movie playback, slideshows, and remote display setups. While not designed for high-speed gaming, it performs admirably for video streaming, business use, and educational applications.

Effortless Plug-and-Play Setup

The CM586 is driver-free and software-free. Simply connect the transmitter to the source device (such as a laptop, camera, or Blu-ray player) and the receiver to the display (monitor, TV, or projector). Power is supplied via USB ports or 5V adapters, making it simple to integrate into any setup.

IR Remote Passback Function

With IR control extension, users can manage their source devices remotely, such as changing media on a Blu-ray player or switching input channels on a decoder — all from the receiver side.

Compatibility and Design

This wireless HDMI extender supports a broad range of HDMI-enabled devices, including laptops, desktops, cameras, projectors, TVs, and gaming consoles. Built from durable ABS plastic, both units are lightweight and heat-resistant. LED indicators conveniently display signal and power status.

Power is delivered via micro USB or USB-C (5V/1A–2A). Depending on the packaging, adapters may be included or powered through the connected device’s USB port.
