BenQ QCast Mirror QP30 Wireless Adapter

The BenQ QCast Mirror QP30 is a wireless adapter designed to connect compatible BenQ projectors to a local network. It plugs into the projector's HDMI port and enables screen mirroring from supported devices without cables. This accessory targets educators and presenters who need quick, cable-free content sharing in meeting rooms or classrooms.

Upgrade from wired HDMI connections

Replacing a physical HDMI cable with the QP30 removes cable clutter and allows the presenter to move freely around the room. The jump is worth it when the projector lacks built-in wireless capability and the environment supports a stable Wi-Fi connection for mirroring. It is not suited for setups that require wired-only infrastructure or projectors without an available HDMI input.
