The MDP2HDMIUSBA Mini DisplayPort® with USB Audio to HDMI® Adapter offers a cost-effective HDMI with audio to Mini DisplayPort link, letting you connect an HDMI-capable HDTV to a device with a Mini DisplayPort output, while saving the expense of upgrading the TV for compatibility. The Mini DisplayPort adapter is the perfect accessory for any of your Microsoft® Surface™ Pro devices with mDP. Simply plug in the USB and Mini DisplayPort connectors to a PC or Mac® and the HDMI connector to an HDMI television/monitor. 2-Channel analog audio will pass through to the HDMI connection, delivering sound to the display side, with the convenience of one HDMI cable.
