Gefen EXT-DVI-2-VGA DVI VGA Blue cable interface/gender adapter

EXT-DVI-2-VGA, DVI to VGA Converts DVI / ADC Graphics for Connection to Analog SVGA Monitors
The Gefen DVI to VGA Conversion Box takes a digital DVI signal and converts it to an analog VGA signal, preserving the clarity of the original signal. Installation is plug and play, taking only minutes.

How It Works
Connect your analog monitor to the HD-15 female connector output of the DVI to VGA Conversion Box. Connect the DVI (M-M) cable between the DVI connector on your computer's graphic card and the DVI input of the DVI to VGA Conversion Box. The converter generates all the compatible digital to analog conversion signals to make the connection between the digital input and the analog output work.
