Null values returned when you use the Win32_VideoController WMI class in Windows 8 or Windows Server 2012

Symptoms

Assume that you have a computer that is running Windows 8 or Windows Server 2012. You run an application that uses the Win32_VideoController Windows Management Instrumentation (WMI) class to collect and configure display settings on the computer. In this situation, null values are returned for the CurrentBitsPerPixel, CurrentHorizontalResolution, and CurrentNumberOfColors properties. Additionally, null values are returned for other current configurations.

Cause

This issue occurs because the device interface classes that are enumerated by the GUID_DISPLAY_DEVICE_ARRIVAL device interface class do not match the device interface classes that are passed by WMI.
