For those who've updated to 4K from 1080 monitors

[tuqqer]

I currently use dual 24-inch 1080 monitors, and they're 28-34 inches from my eyeballs. I spend inordinate amounts of time in front of them, about 12 hours a day. Tons of video conferences on zoom video conference, writing training manuals, video how-tos, and reading.

I wear prescription glasses, but often can get away with 1.25 reading glasses (headed towards 1.5 lately). Increased clarity wouldn't be a bad thing.
