DPI is only half of the picture though (forgive the pun). Viewing distance is the other half, your eyes can't tell the difference between 100 DPI and 300 DPI if you're far enough away.
- m0zg 7y agoBingo. And it's less stressful for the eyes to focus on an object that's further away. Net result: I might actually have some vision left over by the time I retire. Worth the cost.
- seanmcdirmid 7y agoSo what, do you read books ten feet away to reduce eye strain? A modern desk gives you about two feet between you and your monitor, which isn’t overly close, and you’ll still very much notice the difference between 138 and 220 DPI.
- bavell 7y agoOnly for my 150" books ;) I sit 3ft away from my monitors, at that distance I can't notice a difference.
- Dylan16807 7y agoYeah but we're talking about computer screens, not televisions. The viewing distance is around 20-30 inches and 100DPI definitely does not cut it at that distance.
- bavell 7y agoYou're not wrong but at around 30" is where is starts not to matter (for 1440p anyway) and I happen to sit ~36" away from my monitors. See [0]. [0] https://news.ycombinator.com/item?id=21977571 https://news.ycombinator.com/item?id=21977571
- Dylan16807 7y ago'Retina' is just one metric. When it comes to crisp edges, there's still a difference up to 5 or 10 times the PPI. https://en.wikipedia.org/wiki/Hyperacuity_(scientific_term) https://en.wikipedia.org/wiki/Hyperacuity_(scientific_term)
