The DisplayPort to VGA active converter cable, model DP2VGAMM3B, allows you to connect a desktop or laptop computer equipped with DisplayPort directly to a nearby VGA monitor or projector, which avoids having to buy additional adapters and also avoids the clutter of too many cables.
In addition, since the converter cable supports video resolutions up to 1920×1200, it is possible to convert a DisplayPort video source to VGA without deteriorating the video quality.
