The Pro DVI-D to VGA Converter is an ideal solution for connecting newer laptops or computers that output a digital DVI-D video signal to legacy displays, such as projects or monitors, which accept a VGA input. This device converts the digital DVI-D video signal to an analog VGA video signal. Many products on the market, particularly cables, claim this capability; however, most of these products only "adapt" from DVI-D to VGA. Without an active conversion process, there are very few devices that are able to output an analog VGA signal from a DVI-D output. The Pro DVI-D to VGA Converter is an active device which converts a digital DVI-D signal to an analog VGA video signal. This product is easy to use with no software or drivers required. Simply connect the unit & enjoy high definition content on an analog display. The durable metal housing protects the converter & provides for a long life. For added convenience, this device is bus powered from the DVI-D port, so no additional power source is required. A 3.5 mm stereo audio output is also included so that audio can be enjoyed through the display.
