Wireless HDMI transmitter and receiver

The Nyrius TDD20TX transmits Full HD 1080p video from any HDMI source to a TV or projector without cables. It draws power from USB and requires no apps, drivers or Wi-Fi network to operate. The kit includes a transmitter, a receiver and the necessary power cables for a direct point-to-point link.

Replaces long HDMI cable runs

This unit removes the need to route HDMI cables through walls, ceilings or across rooms up to 150 ft in clear line of sight. The upgrade is worth it when installing cables is impractical, when the source and display are in separate rooms, or when a temporary setup must be moved frequently. It does not suit buyers who need 4K resolution, HDR metadata or multi-channel audio formats beyond standard stereo.

Practical limits of the wireless link

Lab testing rates the signal at 50 ft through walls, floors and ceilings and 150 ft with unobstructed line of sight. Auto-channel switching mitigates interference from nearby Wi-Fi and Bluetooth devices. The system streams at 1080p 60 Hz; latency, compression artefacts or frame drops may appear at the range extremes or in dense RF environments.

Questions about this item

What HDMI and power connections do the transmitter and receiver each need?

Both units have an HDMI port and a USB power input; connect the transmitter to your source and the receiver to the display, then supply USB power to each.

Which step in the two-step setup do users most often miss?

Supplying USB power to both the transmitter and the receiver is the step that is frequently overlooked, preventing the link from starting.

How long before the USB power adapters or cables typically need replacing?

With normal indoor use the USB power adapters and cables generally last several years before wear or connector fatigue requires replacement.
