Connect an HDMI display to a Mini-Display Port source with audio. The MDP2HDMIUSBA Mini Display Port with USB (Universal Serial Bus) Audio to HDMI Adapter offers a cost-effective HDMI with audio to Mini Display Port link, letting you connect an HDMI-capable HDTV to a device with a Mini Display Port output, while saving the expense of upgrading the TV for compatibility. Simply plug in the USB (Universal Serial Bus) & Mini Display Port connectors to a PC or Mac & 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. MDP2HDMIUSBA is a passive adapter that requires a DP++ port (Display Port++), meaning that DVI & HDMI signals can also be passed through the port. Compatible with Intel Thunderbolt, when connected directly to a supporting Display Port over Thunderbolt I/O port.
