# VkSwapchainDisplayNativeHdrCreateInfoAMD(3) Manual Page

## Name

VkSwapchainDisplayNativeHdrCreateInfoAMD - Structure specifying display native HDR parameters of a newly created swapchain object

## C Specification

If the `pNext` chain of VkSwapchainCreateInfoKHR includes a `VkSwapchainDisplayNativeHdrCreateInfoAMD` structure, then that structure includes additional swapchain creation parameters specific to display native HDR support.

The `VkSwapchainDisplayNativeHdrCreateInfoAMD` structure is defined as:

    typedef struct VkSwapchainDisplayNativeHdrCreateInfoAMD {
        VkStructureType    sType;
        const void*        pNext;
        VkBool32           localDimmingEnable;
    } VkSwapchainDisplayNativeHdrCreateInfoAMD;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `localDimmingEnable` specifies whether local dimming is enabled for the swapchain.

## Description

If the `pNext` chain of VkSwapchainCreateInfoKHR does not include this structure, the default value for `localDimmingEnable` is `VK_TRUE`, meaning local dimming is initially enabled for the swapchain.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_SWAPCHAIN_DISPLAY_NATIVE_HDR_CREATE_INFO_AMD`

Valid Usage

- It is only valid to set `localDimmingEnable` to `VK_TRUE` if VkDisplayNativeHdrSurfaceCapabilitiesAMD::`localDimmingSupport` is supported.
