Signal quality
Video reaches up to 4K at 30 Hz. Audio supports sampling rates up to 24-bit at 48 kHz.
Radio and reach
Operates on 2400–2483.5 MHz, 5150–5250 MHz, and 5725–5850 MHz bands. In unobstructed conditions, wireless range extends to about 50 m (164 ft).
What ships and how to power
Package includes a USB A-to-C cable. Count on two external power adapters—transmitter and receiver each need 5 V ± 5% at 1 A and will not run without that supply.
Getting started
Connect sources and displays, apply power to both ends, and use the kit without a complex configuration workflow.
