Gefen EXT-VGA-2-DVISP VGA to DVI Scaler Plus

INTRODUCTION

Congratulations on your purchase of the VGA to DVI Scaler Plus. Your complete satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer systems, professional audio/video environments and HDTV systems of all sizes with hard-working solutions that are easy to implement and simple to operate.

The Gefen VGA to DVI Scaler Plus

The VGA to DVI Scaler Plus connects traditional analog video graphic cards (VGA) to DVI compliant digital monitors. The VGA to DVI Scaler PLUS enables users to connect laptops or legacy PC computers equipped with HD-15 video connections to the DVI (digital visual interface) video display format. The VGA to DVI Scaler Plus will also work with component video sources such as DVD players and set top boxes. You can even add a converter cable to achieve HDMI video, or go further and merge external audio sources with the HDMI signal to create HDMI video with embedded digital audio.

How It Works

Simply connect the supplied VGA (M-F) cable to the input side of the VGA to DVI Scaler PLUS. Then connect the DVI monitor or projector to the DVI output of the VGA to DVI Scaler Box. The converter generates the compatible analog to digital conversion signals to make the connection between the analog input and the digital output work. Navigation through the menu is easily done via the buttons in the front of the unit.
