That puts you at roughly 180 dpi, which isn't that far from the 'retina' standard of roughly 220 dpi. But I imagine I can get you sharp text on a lowly 1080p 20

That puts you at roughly 180 dpi, which isn't that far from the 'retina' standard of roughly 220 dpi. But I imagine I can get you sharp text on a lowly 1080p 20 inch display with Windows or Linux at only 110 dpi (or worse) for roughly half the cost at today's prices.
