It's interesting that DEC did horizontal pixel stretching because individual dots would be too precise to be seen because of phosphor latency.
The Commodore 64 had a similar problem with single-pixel latency, which is why the vertical portions of its character ROM are all two pixels wide. Otherwise, the character would be too blurry to be read comfortably on televisions of the era.
I used to love making my own C-64 fonts pixel by pixel and comparing how they looked on a Panasonic portable TV versus my Commodore CM-141 monitor.
