After using a HiDPI display for the last 3 years I would never willingly go back.

And while I'm no particular fan of larger monitors, it seems that a lot of software just assumes it these days. So I would expect 5K @ 27" and 6K @ 30-some inches to be everywhere these days (I guess 4K @ 24" as well).

I guess it's just a matter of being somewhat too expensive to go mainstream, where either a large screen with lower-res or smaller hires screen is much cheaper and "good enough".

Dell has a new 32” 8K monitor that connects via two display ports.

I get 5120x2880, the same vertical resolution as this new LG monitor, but with more horizontal real estate.

I use it with 4 x long (tall) terminal windows.
