Jagged fonts?

Font display quality largely comes down to four things: the physical screen resolution (which is rarely an issue these days, but used to be); the settings of the video adapter (again, not much of a problem on any working system); the resolution and quality setting of the app — that choice, in InDesign, between Fast and Quality display — and then the quality of the font itself. If the font does not have good hinting and other metadata, it may not adapt well to every increment of resolution.

Just off the cuff, this looks like an out of the ordinary font, possibly from a less than meticulous foundry/source, and the ragged display may be caused by a gap between what the system needs for smoothing and clean edges and the font data that isn't that detailed.
