UGREEN 4K@30Hz Wireless HDMI Extender TX and RX 50 Meter Range | 90909A
The UGREEN CM586 (item 90909A) is a wireless HDMI kit made of a transmitter (TX) and a receiver (RX). The transmitter plugs into the HDMI port of your laptop, camera or other source, and the receiver connects to a TV, monitor or projector, sending video and audio without a long HDMI cable. It supports up to 4K@30Hz and reaches up to 50 m in open space with no obstacles.

4K@30Hz picture, 1080P@60Hz compatible: The kit handles video up to 4K at 30Hz and also works at 1080P at 60Hz. For movies, presentations and most office content, this gives a sharp picture on a large screen.

Up to 50 m wireless range: The signal travels up to 50 m (164 ft) when there is a clear line between the two units. Walls and other obstacles shorten the real range, so place the transmitter and receiver with as few obstacles between them as possible.

Factory paired, plug and play: The transmitter and receiver come paired from the factory. No Wi-Fi network, Bluetooth, driver or software is needed: connect both units, power them, and start the screen sharing.

HDMI, VGA and 3.5 mm audio on the receiver: The receiver has an HDMI output, a VGA output and a 3.5 mm audio jack, so it can feed newer HDMI screens, older VGA projectors and monitors, or external speakers. The transmitter has an HDMI connector and a USB-C power port.

Who it's for / Works with
HDMI source devices such as laptops, computers and cameras on the transmitter side, and TVs, monitors and projectors on the receiver side.
Good to know
Both the transmitter and the receiver must be connected to external USB power (5V / 1A) to work. The 50 m range is measured in open space without obstacles.
