The LINDY Multi AV Input to HDMI Presentation Switch allows you to conveniently share content from a variety of devices to a HDMI display, such as a projector, using just a single cable. Each of the connected devices is instantly converted and scaled to a HDMI signal, with the Presentation Switch automatically switching to use the most recently active device, making it ideal for use in class rooms, meeting/conference rooms and auditoriums. For added convenience the Switch also features an Ethernet pass though port and a USB charging (5V 500mA) port, handy for use in the absence of WiFi or for powering mobile devices.
