Intel® 82830M Graphics and Memory Controller Hub (GMCH)
Why does device manager show two different graphics controllers?

The Intel® 830M/830MG chipset has dedicated multimedia engines that execute in parallel to deliver high performance 3D, 2D, and video capabilities. These two engines operating in parallel are seen in Device Manager as 'Intel(R) 82830M Graphics Controller - 0' and 'Intel(R) 82830M Graphics Controller - 1.'

Control Panel Display Adapters

The existence of multiple display devices on a single system allows for a number of possible configuration options. For example, two devices can be driven independently with different content, resolutions, and color depth to increase desktop space. Another possible configuration sends the same content to different monitors to give a presentation to a large audience. For more information on these multi-display configuration options, see: Multi-monitor: Understanding multi-display options.
