personally i think that 27" 2560x1440 is the sweet spot for any type of productivity or any type of use really. 1080p seems to be really popular still but i find there just isn't enough space on it to "a large improvement over a laptop sreen" in my opinion. I also liked the old 30" 2560X1600 monitors I think that is even better but I dont see those around much anymore. dell has one though last time I looked.
