BZBGear BG-Air4Kast Wireless HDMI Extender Kit

The BG-Air4Kast is a transmitter and receiver pair that carries HDMI across a room without a cable. It uses ipcolor STREAM encoding on the 5 GHz band, supports 3840x2160 at up to 60 Hz, and holds latency in the 130 to 180 ms range.

The transmitter has an HDMI loop out for a local monitor, and IR is passed back from the display end so a source can still be controlled from the far side of the room. SSID pairing and channel switching are there to work around a crowded band. HDCP 1.4 and 2.2 are both handled and the link runs at up to 18 Gbps.
