Having the same issue, on my laptop the screen is 2560×1600, but the topmost option for resolution in graphics settings is for 2560×1440, meaning that I either get a letterbox effect (black stripes on top and bottom of the screen) during matches, or a zoomed in version that cuts parts of the right and left sides when forcing the screen resolution through Nvidia settings.
