Question about LG 38wk95c-W

1) What resolution and format (16:9 or 21:9 stretched) do I have when I connect a PS4 PRO and the XBOX One X? 2) Does this monitor have the HDR effect (I don't mean whether it is HDR capable, but explicitly the HDR effect as a selection in the picture. As is the case with the LG 27UK850-W). In certain games, this HDR effect is much nicer than the HDR function in the game. Thank you!
