Msvm_SyntheticDisplayController class

아티클
05/31/2018

Represents the state of the synthetic display controller that is present in each virtual machine configuration. Only one display controller can be active in a virtual machine at any time and the synthetic controller can be activated only when the guest operating system has loaded the required video acceleration services.

The following syntax is simplified Managed Object Format (MOF) code, and it includes all of the inherited properties.
