PS also with this forum, but not on all pages .... see picture

Info and tool for scaling behavior in Windows 10: http://windows10-dpi-fix.xpexplorer.com/

I tried it, both with HDMI or Display Port 1.2 connections; no improvement ... it seems that windows 10 is not there yet, as there are no problems with Windows 8 and older.

In your screenshot example both sets of text look fine to me, though funny enough the "blurry" ones look clearer to me than the "sharp" ones. This might have something to do with subpixel font smoothing.

In short, subpixel smoothing works by virtue of how LCD's display pixels - typically a single pixel is a combination of a Red, Green, and Blue subpixel (usually in that order) - normal rendering uses only the subpixels in each pixel to render the image, while subpixel rendering uses the adjacent red or blue pixels (and occasionally the middle green one) to basically triple the horizontal resolution of the image. This tends to work well, because most monitors arrange the pixels from left to right as Red Green Blue.

Now that's all fine and good, but what if your display isn't RGB but rather BRG or BGR? Then you have to make some adjustments to how Windows calculates it's subpixel rendering. This article will show you how: https://www.laptopmag.com/articles/adjust-cleartype-windows-10

Now even if your monitor is RGB, the previous link may help as it also can control the strength of the smoothing effect, or can allow you to disable it. Only your eyes can be the judge of what looks best.
