ah, and one solution to the font sharpness issue is to use bitmap fonts, indeed. I haven't found good ones though which are available at 16px or above sizes, which are necessary for 2K or 4K displays. Also they are typically quite wide and don't have narrow options.

I found an interesting middle ground though. The old AmigaOS Topaz font as TTF :D http://www.geekometry.com/2013/11/amiga-topaz-truetype-font-...

Joking aside, the narrower variants of the Input font looks pretty good with anti-aliasing: https://input.fontbureau.com/preview/
