# hdrBitDepth

> The number of bits in each color channel for swap chain buffers.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.5/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

```csharp
public static HDRDisplayBitDepth hdrBitDepth { get; set; }
```

### Remarks

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