Transmitter-only KVM extender

This unit is the transmitter half of a wireless HDMI extender system built for presenters, educators and home-theatre users who need to mirror a laptop, phone or console to a distant display. It pairs with a separately sold receiver to create a cable-free link up to 50 metres. The device targets anyone who values quick setup over permanent installation.

Many-to-one switching capacity

Up to eight transmitters can associate with a single receiver, letting multiple users take turns on one screen with a one-click changeover. Each transmitter operates independently so signals do not interfere, making the kit practical for meeting rooms or classroom podiums where several sources share one projector.

Dual-output streaming at 1080p

The receiver delivers simultaneous HDMI and VGA output plus a 3.5 mm audio jack, all driven from the transmitter’s uncompressed 5 GHz 802.11 stream. Latency stays ultra-low even with 3D content at 1080p resolution, and the plug-and-play link is stable within 20 seconds of power-up.
