The ATEN VC180 VGA to HDMI converter with audio allows you to display analog VGA source data on an HDMI digital display with stereo sound quality. It uses two power sources: from the VGA port or from a power adapter (included). The VC180 is powered from the VGA port. However, if your source device is not capable of supplying power, the included power adapter can be used to connect the VC180 to a power outlet. The VC180 is compact, flexible and convenient to install, with no software required.
