# VkDisplayPowerStateEXT(3) Manual Page

## Name

VkDisplayPowerStateEXT - Possible power states for a display

Loading… please wait.

## C Specification

Possible values of VkDisplayPowerInfoEXT::`powerState`, specifying the new power state of a display, are:

    // Provided by VK_EXT_display_control
    typedef enum VkDisplayPowerStateEXT {
        VK_DISPLAY_POWER_STATE_OFF_EXT = 0,
        VK_DISPLAY_POWER_STATE_SUSPEND_EXT = 1,
        VK_DISPLAY_POWER_STATE_ON_EXT = 2,
    } VkDisplayPowerStateEXT;

## Description

- `VK_DISPLAY_POWER_STATE_OFF_EXT` specifies that the display is powered down.

- `VK_DISPLAY_POWER_STATE_SUSPEND_EXT` specifies that the display is put into a low power mode, from which it may be able to transition back to `VK_DISPLAY_POWER_STATE_ON_EXT` more quickly than if it were in `VK_DISPLAY_POWER_STATE_OFF_EXT`. This state may be the same as `VK_DISPLAY_POWER_STATE_OFF_EXT`.

- `VK_DISPLAY_POWER_STATE_ON_EXT` specifies that the display is powered on.
