# vkGetPhysicalDeviceDisplayProperties2KHR(3) Manual Page

## Name

vkGetPhysicalDeviceDisplayProperties2KHR - Query information about the available displays

## C Specification

To query information about the available displays, call:

    // Provided by VK_KHR_get_display_properties2
    VkResult vkGetPhysicalDeviceDisplayProperties2KHR(
        VkPhysicalDevice                            physicalDevice,
        uint32_t*                                   pPropertyCount,
        VkDisplayProperties2KHR*                    pProperties);

## Parameters

- `physicalDevice` is a physical device.

- `pPropertyCount` is a pointer to an integer related to the number of display devices available or queried, as described below.

- `pProperties` is either `NULL` or a pointer to an array of `VkDisplayProperties2KHR` structures.

## Description

`vkGetPhysicalDeviceDisplayProperties2KHR` behaves similarly to vkGetPhysicalDeviceDisplayPropertiesKHR, with the ability to return extended information via chained output structures.

Valid Usage (Implicit)

- VUID-vkGetPhysicalDeviceDisplayProperties2KHR-physicalDevice-parameter
  `physicalDevice` must be a valid VkPhysicalDevice handle

- VUID-vkGetPhysicalDeviceDisplayProperties2KHR-pPropertyCount-parameter
  `pPropertyCount` must be a valid pointer to a `uint32_t` value

- VUID-vkGetPhysicalDeviceDisplayProperties2KHR-pProperties-parameter
  If the value referenced by `pPropertyCount` is not `0`, and `pProperties` is not `NULL`, `pProperties` must be a valid pointer to an array of `pPropertyCount` VkDisplayProperties2KHR structures

Return Codes

On success, this command returns

  - VK_INCOMPLETE

  - VK_SUCCESS

On failure, this command returns

  - VK_ERROR_OUT_OF_DEVICE_MEMORY

  - VK_ERROR_OUT_OF_HOST_MEMORY

  - VK_ERROR_UNKNOWN

  - VK_ERROR_VALIDATION_FAILED
