Red text puzzle

I'm puzzled why red text which I use to annotate or title my images
usually appears blurred on my PC screen, yet when the same JPG is
printed the red is perfectly sharp. Here's an example:

Text requires sharp edges, and when you make red letters on a CRT (or
flat-panel), the edge resolution is determined by only one-third of the
available pixels, and their position is fixed on the face of the
display. With printing, there can be as many "pixels" as needed.
