The HoloLens 2 has a field of view that’s twice as big as before. It doesn’t quite fill your entire field of vision — there’s still clipping — but it’s big enough now that you no longer feel constantly annoyed by a letterbox. Microsoft says that each eye has the equivalent of a 2K display in front of it, but it’s better to think of that as a metaphor than a precise spec. The exact spec is that it has a “holographic density of 47 pixels per degree,” which means that the pixel density is high enough to allow you to read 8-point font.
