_D3DKMDT_MODE_PRUNING_REASON enumeration

Description

The D3DKMDT_MODE_PRUNING_REASON enumeration type contains values that identify the reason why the monitor either supports a display mode or does not support a display mode.

Constants

D3DKMDT_MPR_UNINITIALIZED

A variable of type D3DKMDT_MODE_PRUNING_REASON has not yet been assigned a meaningful value.

D3DKMDT_MPR_ALLCAPS

The monitor does not support the display mode because none of the available monitor capabilities imply support of the display mode.

D3DKMDT_MPR_DESCRIPTOR_MONITOR_SOURCE_MODE

The monitor supports the display mode because of the monitor source mode in the monitor descriptor.

D3DKMDT_MPR_DESCRIPTOR_MONITOR_FREQUENCY_RANGE

The monitor does not support the display mode because of the monitor frequency range in the monitor descriptor.

D3DKMDT_MPR_DESCRIPTOR_OVERRIDE_MONITOR_SOURCE_MODE

The monitor supports the display mode because of the monitor source mode in the monitor descriptor override.

D3DKMDT_MPR_DESCRIPTOR_OVERRIDE_MONITOR_FREQUENCY_RANGE

The monitor does not support the display mode because of the monitor frequency range in the monitor descriptor override.

D3DKMDT_MPR_DEFAULT_PROFILE_MONITOR_SOURCE_MODE

The monitor supports the display mode because of the monitor source mode in the default monitor profile.

The monitor supports the display mode because of the monitor source mode that the display miniport driver recommends.

D3DKMDT_MPR_MONITOR_FREQUENCY_RANGE_OVERRIDE

The monitor supports the display mode because of the monitor frequency range override.

D3DKMDT_MPR_CLONE_PATH_PRUNED

Supported in Windows 7 and later versions.

The display mode is pruned (that is, the monitor does not support the display mode) because other paths in the clone cluster have no mode supported by the monitor.

D3DKMDT_MPR_MAXVALID

Valid enumeration values were exceeded.

Remarks

The setting of the ValidatedAgainstMonitorCaps member of the D3DKMDT_DISPLAYMODE_FLAGS structure indicates whether the monitor supports a display mode or not. If the monitor does not support a display mode, the operating system removes the display mode from the list of display modes that are available to the monitor.

When a display mode is supported, the reason type can be one of the following:

When a display mode is not supported, the reason type can be one of the following:
