How is web browsing at that density? I'm nervous to pick up a 4K display even at 30-32 inches, as I don't think scaling is solved in Windows or on the web (though that's just speculation).
It's fine for me, but I'm used to high density screens. For the longest time, I was using 1680x1050 15" laptop screens at 1:1 (before 1080p became common).
Looking at the HN site, which has pretty small text to start with, I'm perfectly fine reading the text on the screen. If the text is too small, zooming once or twice usually fixes it.
I originally thought 40 or 32 would be the ideal size, but got tired of waiting for the models to come out.
I went into a store and checked out the 28" 4K monitors (which were pretty common), but I wanted IPS, so I ended up with the 27" Dell IPS, which got good reviews and not that much denser than the 28s (for me).
I actually am glad that I did not go 32 or larger because I got acclimated to the added real estate very quickly and wanted more. My desk handles two side by side 27s in landscape. I guess I could have went with two portrait 32s but I definitely could not fit in dual 40s.
I don't know if I can handle four monitors (more head turning than I have now), but I've got some mini monitors in addition to my two main ones, and I still feel at times that I don't have enough screen real estate when I'm multitasking.
