Field Documentation

NvU16 _NV_HDR_CAPABILITIES_V1::desired_content_max_frame_average_luminance

Desired maximum Frame-Average Light Level (MaxFALL) of HDR content ([0x0001-0xFFFF] = [1.0 - 65535.0] cd/m^2)

NvU16 _NV_HDR_CAPABILITIES_V1::desired_content_max_luminance

Maximum display luminance = desired max luminance of HDR content ([0x0001-0xFFFF] = [1.0 - 65535.0] cd/m^2)

NvU16 _NV_HDR_CAPABILITIES_V1::desired_content_min_luminance

Minimum display luminance = desired min luminance of HDR content ([0x0001-0xFFFF] = [1.0 - 6.55350] cd/m^2)

struct { ... } _NV_HDR_CAPABILITIES_V1::display_data
NvU16 _NV_HDR_CAPABILITIES_V1::displayPrimary_x0

NvU16 _NV_HDR_CAPABILITIES_V1::displayPrimary_x1

x coordinate of color primary 1 (e.g. Green) of the display ([0x0000-0xC350] = [0.0 - 1.0])

NvU16 _NV_HDR_CAPABILITIES_V1::displayPrimary_x2

x coordinate of color primary 2 (e.g. Blue) of the display ([0x0000-0xC350] = [0.0 - 1.0])

NvU16 _NV_HDR_CAPABILITIES_V1::displayPrimary_y0

y coordinate of color primary 0 (e.g. Red) of the display ([0x0000-0xC350] = [0.0 - 1.0])

NvU16 _NV_HDR_CAPABILITIES_V1::displayPrimary_y1

y coordinate of color primary 1 (e.g. Green) of the display ([0x0000-0xC350] = [0.0 - 1.0])

NvU16 _NV_HDR_CAPABILITIES_V1::displayPrimary_y2
