Expand description

A structure defining the limits and attributes of a display or framebuffer.

This structure is used to define the limits for modes programmed as detailed timings by the OS. The VESA EDID is useful background information for many of these fields. A data property with this structure under the key kIOFBTimingRangeKey in a framebuffer will allow the OS to program detailed timings that fall within its range. Field: __reservedA Set to zero. Field: version Set to zero. Field: __reservedB Set to zero. Field: minPixelClock minimum pixel clock frequency in range, in Hz. Field: minPixelClock maximum pixel clock frequency in range, in Hz. Field: maxPixelError largest variation between specified and actual pixel clock frequency, in Hz. Field: supportedSyncFlags mask of supported sync attributes. The following are defined:
kIORangeSupportsSeparateSyncs - digital separate syncs.
kIORangeSupportsSyncOnGreen - sync on green.
kIORangeSupportsCompositeSync - composite sync.
kIORangeSupportsVSyncSerration - vertical sync has serration and equalization pulses.
kIORangeSupportsVRR - variable refresh rate.
Field: supportedSignalLevels mask of possible signal levels. The following are defined:
kIORangeSupportsSignal_0700_0300 0.700 - 0.300 V p-p.
kIORangeSupportsSignal_0714_0286 0.714 - 0.286 V p-p.
kIORangeSupportsSignal_1000_0400 1.000 - 0.400 V p-p.
kIORangeSupportsSignal_0700_0000 0.700 - 0.000 V p-p.
Field: supportedSignalConfigs mask of possible signal configurations. The following are defined:
kIORangeSupportsInterlacedCEATiming Supports CEA style interlaced timing:
Field 1 vertical blanking = specified vertical blanking lines.
Field 2 vertical blanking = vertical blanking lines + 1 line.
Field 1 vertical offset = specified vertical sync offset.
Field 2 vertical offset = specified vertical sync offset + 0.5 lines.
kIORangeSupportsInterlacedCEATimingWithConfirm Supports CEA style interlaced timing, but require a confirm. Field: minFrameRate minimum frame rate (vertical refresh frequency) in range, in Hz. Field: maxFrameRate maximum frame rate (vertical refresh frequency) in range, in Hz. Field: minLineRate minimum line rate (horizontal refresh frequency) in range, in Hz. Field: maxLineRate maximum line rate (horizontal refresh frequency) in range, in Hz. Field: maxHorizontalTotal maximum clocks in horizontal line (active + blanking).
