SDL_GetDisplayContentScale - Get the content scale of a display.
Defined in SDL3/SDL_video.h
#include "SDL3/SDL.h"
float SDL_GetDisplayContentScale(SDL_DisplayID displayID);
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.
Returns the content scale of the display, or 0.0f on failure; call
SDL_GetError () for more information.
This function should only be called on the main thread.
This function is available since SDL 3.2.0.
