Also, check your graphics card configuration (Nvidia Control Panel or AMD counterpart). There should be a “scaling” thingy, try to fiddle with these settings. Looks like your current settings does no scaling at all, so the fixed 1024x768 appears small compared to native resolution. Selecting “aspect ratio” should make the image scale so it fits as much of the screen while preserving proportions - so full height and black bars on sides. Selecting “full scrren” will make the 2D screen go fully widescreen, but at the cost of horizontal stretching. These settings won’t affect 3D at all if your 3D resolution is set to native. Take note that the display (as in, the monitor itself) can have it’s own scaling settings.
