With any reasonable resolution screen (1080p or more), you can have both good preservation of letter forms and a non-blurry image, simply by applying a sharpening filter after antialiasing. Some image downsampling methods, such as Lanczos filtering, effectively do this for you. The tradeoff is one can detect some very fine 'ringing' artifacts around the sharpened transitions, but these don't impact readability in any way.
