• Properties

Properties

The SupportedDisplayFeaturesDescriptor class has these properties.

ActiveOffSupported

Data type: boolean

Access type: Read-only

Support for active off and very low power. The display consumes less power when it receives a timing signal that is outside the declared active operating range. The display will revert to normal operation if the timing signal returns to the normal operating range. Examples of timing signals outside the normal operating range are no sync signals or no DE signal.

DisplayType

Data type: uint8

Access type: Read-only

Type of display for the monitor. The following table lists possible values.

Value	Meaning
0 (0x0)	Monochrome/grayscale display
1 (0x1)	RGB color display
2 (0x2)	Non-RGB multicolor display

GTFSupported

Data type: boolean

Access type: Read-only

Indicates whether the display has GTF support. If True, the display supports timings based on the GTF standard using default GTF parameter values.

HasPreferredTimingMode

Data type: boolean

Access type: Read-only

Indicates whether the display has a preferred timing mode. If True, the first detailed timing block contains the preferred timing mode of the monitor. Use of preferred timing mode is required by EDID v.1.3 and higher.

sRGBSupported

Data type: boolean

Access type: Read-only

If True, the display supports sRGB.

StandbySupported

Data type: boolean

Access type: Read-only

Indicates whether the display supports VESA Display Power Management Signaling (DPMS) standby. If True, DPMS standby is supported.

SuspendSupported

Data type: boolean

Access type: Read-only

Indicates whether the display supports VESA Display Power Management Signaling (DPMS) suspend. If True, DPMS suspend is supported.
