(This is the legacy documentation for SDL2, the previous stable version; SDL3 is the current stable version.)

SDL_GetCurrentDisplayMode

Get information about the current display mode.

Header File

Syntax

int SDL_GetCurrentDisplayMode(int displayIndex, SDL_DisplayMode * mode);

Function Parameters

int	displayIndex	the index of the display to query.
SDL_DisplayMode *	mode	an SDL_DisplayMode structure filled in with the current display mode.

Return Value

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

Remarks

There's a difference between this function and 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.
