The title is a little misleading. Most of the poster's problems come from the small dot size. If he had a 48'' 4k display, each pixel would be the same size as on a 24'' 1080p display. Zero font size problems, no need to scale anything. I use a curved tv of this size (at a low brightness setting ;)) and notice only one problem from the ones the poster mentioned: sometimes the amount of windows on the screen can be a little distracting. However it is easily offset by the productivity gain from having all necessary windows constantly visible. Also, if you need to concentrate on just one window temporarily, just move it to another virtual desktop. Takes no effort.
