# VkDisplayModeParametersKHR(3) Manual Page

## Name

VkDisplayModeParametersKHR - Structure describing display parameters associated with a display mode

## C Specification

The `VkDisplayModeParametersKHR` structure is defined as:

    typedef struct VkDisplayModeParametersKHR {
        VkExtent2D    visibleRegion;
        uint32_t      refreshRate;
    } VkDisplayModeParametersKHR;

## Members

- `visibleRegion` is the 2D extents of the visible region.

- `refreshRate` is a `uint32_t` that is the number of times the display is refreshed each second multiplied by 1000.

## Description

| Note For example, a 60Hz display mode would report a `refreshRate` of 60,000.

Valid Usage

- The `width` member of `visibleRegion` must be greater than `0`

- The `height` member of `visibleRegion` must be greater than `0`

- `refreshRate` must be greater than `0`
