At some point additional resolution is a dimishing return. The human eye has limits.

5K 27” looks usefully better than 4K 27” to my middle aged eyes.

I’d prefer that to not be so, because 5K panels are so much more expensive. But in a side by side comparison it’s very obvious.

But the market has spoken: a quality 4K display is very good, certainly good enough, and the value for money is great.

I’m ok with spending more on a better display that I spend so much time with. The cost per use-hour is still very, very low.

We're approaching that point but are not there yet
