My current desktop office monitor which is connected to my MacBook Pro (Retina, 13", Mid 2014) is a Dell U2312HM. I am now finding the screen size frustrating small for me particularly when editing and viewing photos and working with Microsoft Office and the like. A blog post at Wirecutter on 4K monitors has got me thinking about updating my monitor. I am not sure I can or would benefit from a 4K monitor or more specifically what 4K really offers over a decent non-4K monitor and hence would appreciate one's thoughts on that as well as alternatives, I guess in the 27" monitor size. Dell, as a price guide sell the P2715Q (the one recommended by Wirecutter) for AU$999 which is probably pushing my budget here. The Dell UltraSharp 27 InfinityEdge Monitor - U2717D is $AU849 which I could live with for example. Oh I really don't want to change my laptop at this point in time. Thoughts?
