What's the HoloLens2 resolution?

[fr00g]

It says that HoloLens2 resolution is 2K per eye and has over 2.5k radiant (light points per radian) holographic density?

Can anyone give me a more detailed explanation on how these radiants are calculated or what it means in terms of pixels?

thanks for raising this @fr00g . A similar question was raised here https://forums.hololens.com/discussion/92/whats-a-light-point#:~:text=Another%20measurement%20is%202.... Although it's regarding HL1, the explanation from Ashraf is still applicable in regards of radiant/lightpoints
