At 95 DPI, basically, you have a choice: either some amount of
blurriness, or some amount of corrupting the intended letter shape.
The knob is called hinting. Choose aggressive (“full”) hinting,
strokes are pulled to integer pixel coordinates, you get crisp ugly
letters. Choose slight hinting, letter shape is preserved as much as
practical, but some strokes will be at fractional coordinates and thus
blurry.

On a typical landscape-oriented monitor, vertical strokes can benefit
from subpixel hinting, although some call the result “rainbow soap”.

Both problems (blurriness and letter misshaping) pretty much disappear
at 2x pixel density or around 192 DPI. (However a new one appears —
you start to hate bitmap graphics, as it is either too blurry or too
small.)
