The Benq QP20 (part number 5A.JH328.10E) is a wireless presentation accessory designed to enable cable-free screen sharing with compatible projectors in business, education, and collaborative environments. It allows presenters to display content from computers or mobile devices without a direct video cable connection, supporting cleaner installations and more flexible room usage.
The QP20 operates as an external wireless receiver that connects to supported projectors via HDMI and USB, providing network-based screen mirroring and presentation functionality depending on firmware support. It is intended for general presentation and multimedia use rather than latency-critical video playback, and is supplied as a genuine accessory with compatibility limited to specific projector models that officially support the QP wireless platform.
