The Marmitek Connect VH51 is a VGA-to-HDMI converter designed to connect computers and other VGA-output sources to modern HDTV displays and projectors that accept only HDMI. It converts the VGA video signal and a 3.5 mm stereo audio signal into a combined HDMI output at selectable 720p or 1080p resolution.

An automatic and manual zoom function allows the image to be scaled to fit the connected screen, and no software or driver installation is required. The unit is powered via USB, so no separate power supply is needed at the source end.
