typedef struct SDL_DisplayMode
{
    SDL_DisplayID displayID;        /**< the display this mode is associated with */

    int w;                          /**< width */
    int h;                          /**< height */
    float pixel_density;            /**< scale converting size to pixels (e.g. a 1920x1080 mode with 2.0 scale would have 3840x2160 pixels) */
    float refresh_rate;             /**< refresh rate (or 0.0f for unspecified) */
    int refresh_rate_numerator;     /**< precise refresh rate numerator (or 0 for unspecified) */
