Since: 14

Summary

Member Variables

Name	Description
uint32_t id	ID of the display. The value must be a non-negative integer.
char name	Name of the display.
bool isAlive	Whether the display is active. The value true means that the display is active, and false means the opposite.
int32_t width	Width of the display, in px. The value must be a non-negative integer.
int32_t height	Height of the display, in px. The value must be a non-negative integer.
int32_t physicalWidth	Physical width of the display, in px. The value must be a non-negative integer.
int32_t physicalHeight	Physical height of the display, in px. The value must be a non-negative integer.
uint32_t refreshRate	Refresh rate of the display, in Hz. The value must be a non-negative integer.
uint32_t availableWidth	Width of the available area on a 2-in-1 device, in px. The value must be a non-negative integer.
uint32_t availableHeight	Height of the available area on a 2-in-1 device, in px. The value is an integer greater than 0.
float densityDPI	Physical pixel density of the display, that is, the number of pixels per inch. The value must be a floating point number greater than 0. The unit is px. Generally, the value is 160.0 or 480.0. The actual value depends on the optional values provided by the device in use.
float densityPixels	Logical pixel density of the display, which is the scaling coefficient between physical pixels and logical pixels. The value is a floating point number greater than 0 and is restricted by the range of densityDPI. The value range is [0.5, 4.0]. Generally, the value is 1.0 or 3.0. The actual value depends on the density DPI provided by the device in use.
float scaledDensity	Scaling factor for fonts displayed on the display. The value must be a floating point number greater than 0. Generally, the value is the same as that of densityPixels.
float xDPI	Exact physical pixels per inch of the display in the X dimension. The value must be a floating point number greater than 0.
float yDPI	Exact physical pixels per inch of the display in the Y dimension. The value must be a floating point number greater than 0.
NativeDisplayManager_Rotation rotation	Clockwise rotation angle of the display.
NativeDisplayManager_DisplayState state	State of the display.
NativeDisplayManager_Rotation orientation	Orientation of the display.
NativeDisplayManager_DisplayHdrFormat* hdrFormat	All the HDR formats supported by the display.
NativeDisplayManager_DisplayColorSpace* colorSpace	All the color spaces supported by the display.
