This monitor displays coloured pixels adequately. I imagine it also displays black and white pixels, and come to think of it monochrome pixels, and for that stone age aesthetic you could go with green and black pixels only; but I can't review its performance for any of those. I've just displayed coloured pixels, but i have displayed many now, and I can assure you all of them were in the right place at the right time and seemed to be the right colour too. (Just going by eye on that one, it's not like I sit there with Pantene colour swatches checking, that would be weird).
