Features

HDMI Wireless Extender Ideal for Displaying 4K Video in Classrooms and Conference Rooms
This complete wireless transmitter and receiver system is recommended for video presentations in conference rooms, trade shows, home theaters, digital signage and other applications in which connecting long video cables could be a burden. The B127-1A1-WHD4CH extends 4K video and audio from a USB-C source device to an HDMI display up to 65 feet (20 meters) away. No bulky or costly cabling infrastructure is needed.

Wireless Transmission Saves You Money on Cable and Installation Costs
The B127-1A1-WHD4CH eliminates more than just hassles. You’ll save on the costs of cabling infrastructure and the labor to install it. Cable clutter is reduced, and you will enjoy more flexibility in placement of the source and display with no cables to relocate when you want to reconfigure the room. The transmitter and receiver units communicate over a 5.18–5.24 GHz wireless frequency that allows fast data transmission and reduced interference from other wireless sources. Be sure the transmitter and receiver share a direct line of sight for best results.

The B127-1A1-WHD4CH ensures Ultra HD performance in a one-to-one application, where there is less obstruction to occur. It supports 4K video resolutions (3840 x 2160) at 60 Hz. LEDs indicate when the transmitter and receiver units are receiving power, building a wireless connection between the units and transmitting data.

Plug-and-Play Operation for Quick Setup and Immediate Use
The wireless transmitter and receiver set works right out of the box with no software required. Connect the receiver to the display’s HDMI port and the transmitter to the source’s USB-C port.
