It is not a new thing that for some reason that using big monitors is rare, but I wonder why it is that way?
It used to be that the big monitors was really expensive. In fact if we go back far enough it was even so that running a big high resolution monitor required fancy graphics hardware, but now all but the most basic graphics card will support high resolutions and a an average one even support gaming in high resolution. So it is that until somewhat recent the costs was high and therefore the perception is that it is still so causing no one to consider going big.
I have been using a 40" 4K monitor as my main unit for 1½ year now and I can not imagine going back to say 2x27" or 2x24". The 40" 4K offers a pixel size similar to to a 1440p 27"so there is no issue with objects being too small like there can be with a 32" 4K and compared to running two monitors there is much freedom not having to work around the bezels. A 40" 4K computer monitor can be had for $600 or so.
Really I only see one reason to hold back and that is there is not many models to choose from, so one in you favorite brand may not be available but that will change since the 4K TV's which are now the norm means 4K panels are becoming ever cheaper.
Have you considered making your next computer monitor a 40"?
