This is probably a dumb question but I haven't purchased an external monitor in a very, very long time. Now I'm working at home more and thinking about an external monitor for my 16" MBP. I mostly write and research. I do not game. I do want text to be perfectly crisp and clear since I stare at it all day. I'm thinking of something in the 27-30" range. With that in mind, what resolution do I need to text as crisp and clean as it is on the MBP's retina display? I'm assuming I need a 4K display instead of 1080p? Or is there something else I should be looking at. Again I apologize for what is probably a dumb question.
