Panasonic has launched a new wireless presentation system that allows up to four presenters at a time to display visual and audio content on a Panasonic display or projector. Simply connect the transmitter button to a PC’s USB and HDMI ports and press a button to share content, including presentations with video.
The presenter’s PC can also be switched by pressing a button. No set-up, software or driver installation is required. The Panasonic Wireless Presentation System is available in two versions: basic, with a set-top-box; or cable-less with an SDM board receiver that fits perfectly inside the Intel SDM expansion slot of a Panasonic SQ1 display.
