public static D3DHDRDisplayBitDepth D3DHDRBitDepth { get; set; }
```

### Remarks

The bit count also defines the method Unity uses to render content to the display. When set to `10`, Unity will use R10G10B10A2 buffer format, Rec2020 primaries and ST2084 PQ encoding. When set to `16`, Unity will use R16G16B16A16 buffer format, Rec709 primaries and linear color (no encoding).
