From using the DK2 I got the impression that the issue wasn’t screendoor effect (fill percentage) but rather the size of the pixels. The spaces between the pixels didn’t really seem noticeable, it was just the shear size of each pixel that bothered me. Perhaps that’s just a fault in my perception though and the screen door was actually what I was experiencing.
IIRC DK2 is an upgrade to two seperate 1080p’s.
EDIT: huh. It’s not clear. Different articles say different things. They all seem to say that there are two separate screens, but some are saying they’re 1080p and others are saying they’re 960x1080. Not sure which is right, wish I had spent more time with the occulus devs and asked this stuff myself.
