03/29/2022

The Win32_VideoController WMI class represents the capabilities and management capacity of the video controller on a computer system running Windows.

Hardware that is not compatible with Windows Display Driver Model (WDDM) returns inaccurate property values for instances of this class.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.
