On: Nanofont3x4: Smallest readable 3x4 font with lower...

This seems to be a problem of screen resolution, not font. The number of pixels of the font doesn't have to relate to the size on your monitor at all.

I also can't read it at 100% on a high-density monitor, but I can read it very comfortably at a normal size, even though glyphs have so few features.

Screen resolution is literally the amount of pixels that fit on a square inch.

Not that's density, measured in dpi (dots per inch).

You wouldn't say that Super Mario is unplayable because it's too tiny at 256x224. You would just have you 4k TV show big pixels and get on with the game.
