UGREEN CM586 Wireless HDMI Extender 4K@30Hz, 50m – Wireless HDMI & VGA Transmitter Receiver Kit

The UGREEN CM586 Wireless HDMI Extender is a wireless video and audio transmission solution designed to connect a compatible source device to a television, monitor or projector without running a long HDMI cable between them.

Also identified by product number 90909A, this transmitter-and-receiver kit supports video transmission up to 4K@30Hz and advertises a wireless transmission distance of up to 50 metres (164 feet) under unobstructed conditions. Its receiver provides HDMI and VGA connectivity, along with a 3.5mm audio output for compatible setups.

With dual-band wireless connectivity, plug-and-play setup and support for common display devices, the CM586 is a practical option for presentations, home entertainment, classrooms, offices and other environments where a long physical HDMI cable is inconvenient.

Common Problems with Traditional HDMI Connections

Wired HDMI connections work well, but they can create practical challenges when the source device and display are far apart.

Common problems include:

• Long HDMI cables running across rooms
• Cable clutter around televisions and projectors
• Difficult installation in meeting rooms and classrooms
• Limited placement options for a laptop or media player
• Extra cable management for temporary presentations
• Difficulty connecting devices across open spaces

The UGREEN CM586 provides a wireless alternative by transmitting video and audio from a source device to a compatible display through its dedicated transmitter and receiver.

Smart Solution: Wireless HDMI Transmission up to 50m

The UGREEN CM586 Wireless HDMI Extender uses a transmitter connected to the source device and a receiver connected to the display.

Source device → Wireless transmitter → Wireless signal → Receiver → TV, monitor or projector

The kit supports 2.4GHz and 5GHz wireless frequency bands, with a maximum advertised range of 50 metres in unobstructed conditions. Actual range and stability depend on walls, interference, placement and the selected resolution.

Key Features

1. Up to 4K@30Hz Resolution

The CM586 supports video resolutions up to 4K at 30Hz, making it suitable for compatible media playback, presentations and general display use.

It is also listed as backward compatible with 1080p@60Hz. Actual output depends on the source device, display, connection type and wireless conditions.

2. Wireless Transmission up to 50 Metres

The kit advertises wireless transmission up to 50m (164ft) under unobstructed conditions.

This can help when connecting a laptop or media player to a display positioned across a room or open area. Walls and other obstacles can reduce the practical range.

3. Dual-Band Wireless Connectivity

The CM586 supports wireless frequency bands in the 2.4GHz and 5GHz ranges, helping it operate across different wireless environments.

The extender uses its own transmitter and receiver link; a home Wi-Fi router or internet connection is not generally required for the direct connection between the two units.

4. HDMI Transmitter and Receiver

The transmitter connects to the HDMI output of a compatible source device, while the receiver connects to the display.

This arrangement is useful for laptops, desktop computers, media players, compatible game consoles and other HDMI sources. Check the device’s output compatibility before purchasing.

5. HDMI and VGA Receiver Outputs

The receiver includes:

• HDMI output
• VGA output
• 3.5mm audio output
• USB-C power input

This combination helps support both modern HDMI displays and compatible older VGA projectors or monitors. VGA does not carry audio, so a separate audio connection may be necessary when using VGA. Some documentation lists VGA output up to 1080p@60Hz, so confirm the supported resolution for your specific output configuration.

6. Plug-and-Play Setup

The CM586 is designed for straightforward installation without requiring a dedicated software installation for basic operation.

Connect the transmitter to the source, connect the receiver to the display, power both units and establish the wireless link according to the supplied instructions.

7. One-Click Connection

The transmitter features a connection button for convenient pairing or reconnection, depending on the supplied version.

This makes it easier to establish the wireless display link without navigating a complicated setup process.

8. Audio Transmission Support

The CM586 is designed to transmit video and audio from compatible HDMI sources. The documentation lists audio sampling up to 24-bit/48kHz.

When using the receiver’s VGA output, remember that VGA carries video only. Use the receiver’s 3.5mm audio output with a compatible audio device when required.

9. USB-C Power Connection

Both the transmitter and receiver require power through their power ports. The product documentation specifies an external 5V, approximately 1A power supply for each unit, with two USB-A-to-USB-C power cables listed in the package documentation.

A suitable power adapter may need to be supplied separately, depending on the retail package.

10. Compact, Practical Design

The separate transmitter and receiver allow flexible placement without needing a long HDMI cable between the two locations.

The receiver is designed with HDMI, VGA, audio and power connections to support a variety of display setups.
