Talking with Ormand Lionheart about the images in a video I made, he mentioned Dynamic Super Resolution. A bit of research shows this is a way to make your 2k-1920×1080 monitor look more like a 4k monitor. The keywords are “more like”.
The video explains and shows what is being talked about. It touches on the fact that a 1080 or 2k monitor is physically limited to showing that fixed number of pixels. Nothing anyone can do will change that. You have 1920×1080 pixels, horizontal and vertical, for a total of 2,073,600 pixels. Those manufactured into the screen. To get more pixels you need a screen manufactured with more.
