VisionTek Active DisplayPort to VGA converter is a DisplayPort to Active VGA converter that receives both video and audio streams from an upstream DisplayPort Source link and converts to a VGA output. The DisplayPort to VGA adapter lets you connect your DisplayPort video source (Macbook, Macbook Pro, Macbook Air, etc.) to any VGA display, eliminating the expense of having to upgrade to a DisplayPort-capable monitor. The DisplayPort adapter offers an active conversion and easy connectivity directly without any external power input and is able to handle resolutions up to 1920 x 1200. Use it to mirror your display to another monitor, or extend your desktop to increase your workspace.
