At what seating distance? IMO at 22-25", text on it looks pretty poor, especially with non 2X scaled resolutions. I had it for a week and just couldn't stand it -
Asus ProArt PA329CV.
Seating distance will vary with a.o the user`s vision, but also preferences, posture and so on. Got the 32 on a Egotron arm and have placed it all sorts of positions depending upon what I`m at, mood or whatever. Some people prefer their monitor several inches above the desk, others want it to lick the desk. Which makes the stand and the adjustment range rather important to some, whereas it doesn`t matter to others.
There is no universal answer, people will figure out what`s good for them and adjust accordingly. Same goes with (related) scaling, monitor size and dpi. It`s difficult to suggest "the right monitor", as we might have grown accustomed to something which IS great, WAS great, or not brilliant at all. I`m accustomed to mine, but I bet I`d be wanting something else if doing a side by side comparison with a really good one.
I did try out the 30" Cinema Display back in the day, it was kind of a grail (Apple was always great at pushing DPI), but when I tested it I actually realized it was way too big and figured out 27 was the right size when they arrived with reasonable DPI and quality. And here I am, on a 32. People tend to adapt to what they have to work with, and when it works it kind of becomes the "new ideal".
No matter the size and dpi, I`d most of all believe it is wise to get a VESA monitor which doesn`t cause all sorts of strain to the eyes.
