Secondary displays require both hardware and driver support; some graphics cards may support overlay on the second display while their drivers may not yet support it (note: recent (July 2008) graphics chipset driver bugs can cause most video formats apart from mpeg2 to work on both monitors, and mpeg2 only on the primary with most players).
Shared graphics power components, allowing non-graphics drivers to participate in the power management of a graphics device. Shared texture improvements , increasing the types of textures that can be shared across processes and Direct3D devices, adding support to monochrome with minimal memory copying.

The DisplayLink VGC software is based on proprietary adaptive graphics technology.
Dedicated graphics cards are not bound to the motherboard, and therefore most are removable, replaceable, or upgradable. They are installed in an expansion slot and connected to the motherboard.
