# signalConfig

Information about display setup.

## Declaration

```occ
UInt32 signalConfig;
```

## Discussion

Discussion kIOAnalogSetupExpected is set if display expects a blank-to-black setup or pedestal. See VESA signal standards.kIOInterlacedCEATiming is set for a CEA style interlaced timing: Field 1 vertical blanking = half specified vertical blanking lines. Field 2 vertical blanking = (half vertical blanking lines) + 1 line. Field 1 vertical offset = half specified vertical sync offset. Field 2 vertical offset = (half specified vertical sync offset) + 0.5 lines.
