FrequencyRangeDescriptor class

The FrequencyRangeDescriptor WMI class represents a container for characteristics of a supported frequency range. Instances of this class are elements of the MonitorFreqRanges array in WmiMonitorListedFrequencyRanges.

Syntax

class FrequencyRangeDescriptor
{
  uint8  Origin;
  uint32 MinVSyncNumerator;
  uint32 MinVSyncDenominator;
  uint32 MaxVSyncNumerator;
  uint32 MaxVSyncDenominator;
  uint32 MinHSyncNumerator;
  uint32 MinHSyncDenominator;
  uint32 MaxHSyncNumerator;
  uint32 MaxHSyncDenominator;
  uint32 ConstraintType;
  uint32 ActiveWidth;
  uint32 ActiveHeight;
  uint32 MaxPixelRate;
};
