The DP2HDMIUSBA Display Port to HDMI Adapter with USB (Universal Serial Bus) Audio is a cost-effective solution that lets you connect an HDMI capable HDTV to a device with Display Port output, avoiding the expense of upgrading the TV for compatibility. Featuring a compact design, the Display Port to HDMI converter/adapter requires minimal space & draws power through the USB (Universal Serial Bus) connection, so that no bulky external power supply or outlet is required. Simply plug the integrated USB (Universal Serial Bus) & Display Port connectors into your PC or Mac, & use the desired length of HDMI cable to connect to your television/monitor. The 2-channel analog audio signal passes through the HDMI connection, delivering the video & accompanying audio signals using a single HDMI cable. DP2HDMIUSBA is a passive adapter that requires a DP++ port (Display Port++), meaning that DVI & HDMI signals can also be passed through the port.
