NAME

       SDL_GetDisplayContentScale - Get the content scale of a display.

SYNOPSIS

       #include <SDL3/SDL_video.h>

       float SDL_GetDisplayContentScale(SDL_DisplayID displayID);

DESCRIPTION

       The  content  scale  is  the  expected  scale  for  content based on the DPI settings of the display. For
       example, a 4K display might have a 2.0 (200%) display  scale,  which  means  that  the  user  expects  UI
       elements to be twice as big on this display, to aid in readability.

       After  window  creation, SDL_GetWindowDisplayScale() should be used to query the content scale factor for
       individual windows instead of querying the display for a window and calling this function,  as  the  per-
       window content scale factor may differ from the base value of the display it is on, particularly on high-
       DPI and/or multi-monitor desktop configurations.

FUNCTION PARAMETERS

       displayID
              the instance ID of the display to query.

RETURN VALUE

       for more information.

THREAD SAFETY

       This function should only be called on the main thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
