# SDL_GetCurrentDisplayMode

Get information about the current display mode.

## Header File

Defined in [SDL_video.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_video.h), but apps should _only_ `#include "SDL.h"`!

## Syntax

```c
int SDL_GetCurrentDisplayMode(int displayIndex, SDL_DisplayMode * mode);

```

## Function Parameters

|                      |                                                                                         |
| -------------------- | --------------------------------------------------------------------------------------- |
| **displayIndex**     | the index of the display to query                                                       |
| **mode**             | an [SDL_DisplayMode](SDL_DisplayMode) structure filled in with the current display mode |

## Return Value

Returns 0 on success or a negative error code on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

There's a difference between this function and
[SDL_GetDesktopDisplayMode](SDL_GetDesktopDisplayMode)() when SDL runs
fullscreen and has changed the resolution. In that case this function will
return the current display mode, and not the previous native display mode.

## Version

This function is available since SDL 2.0.0.
