@neauoire Not off the top of my head, based on a rough visual inspection I'd say it has about... 40+ pixels per centimeter? And the screen is roughly 6.5x6.5 cm^2.
So that's around ~300 pixels in both direction, but it's very possible I miscounted, counting pixels is hard.
Not sure if other models have different screen sizes.
I tried to find an official count in the docs and emulator config files I have but couldn't.
