Wireless HDMI Extender

The Gefen AV246 is a wireless HDMI extender that transmits audio and video up to 100 metres or 328 feet. It operates on 5.8G and 2.4G bands with 80ms latency. The unit accepts 4K input and delivers 1080p output. It suits presenters, educators and home users who need cable-free projection.

2-in-1 Transmitter and Receiver

The kit works as a full transmitter-and-receiver pair or the receiver alone mirrors phones, tablets and laptops directly. Included accessories are a Mini HDMI 8K adapter, a Micro HDMI 8K adapter and two standard HDMI extension cables. USB power keeps the compact dongles portable for meeting rooms, classrooms or living rooms.

Sustained Wireless Link

Dual-band 5.8G and 2.4G operation maintains a stable connection during long sessions. The fixed 80ms latency stays consistent whether streaming a feature-length film or running a day of presentations. No driver installation is required, so the link remains active across reboots and input changes without manual intervention.
