> At the common resolutions and with purpose-built CRT monitors, pixel boundaries were quite clear and distinguishable. Being able to clearly resolve individual pixels (which I agree was a thing at resolutions like 640x480 or 800x600. 1024x768 is pushing it already though) is not the same as seeing "crisp" boundaries between them. The latter is what I was objecting to. 320x200 (sometimes also 320x240 or the like) is a special case since it was pixel-doubled on more modern VGA/SVGA display hardware, so that's the one case where a single pixel was genuinely seen as a small square with rather crisp boundaries, as opposed to a blurry dot.
