A display corresponds to a physical screen which is the default display. Whenever
eglGetDisplay()is called withEGL_DEFAULT_DISPLAYdisplay type, a connection to this default display is returned. One will obtain connection to same default display even when such call is made in different applications because there is only one default display.If you working on X11 or Wayland windowing system then
EGL_PLATFORM_X11_SCREEN_KHR,KHR_platform_waylandextensions allow to obtain corresponding display. In that caseeglGetPlatformDisplay()with parameterEGL_PLATFORM_X11_KHRorEGL_PLATFORM_WAYLAND_KHRwill return corresponding display connections.Please look at the extensions:
