I have a late-2014 iMac 27" 5k that our family uses as the primary, do everything computer. I work from home and my office is setup with a MBP mid-2014 with three external Dell 24" monitors. I like the portability of the MBP but a couple of years ago I started an aerial photography company so my editing needs have skyrocketed. The laptop is doing an ok job but it's obvious that the iMac would blister it should i put side by side. I am considering pulling down the 2 of the 3 external monitors and putting a 5k 27" iMac in my office and just use my laptop for portability as needed for my real job (not related to photography). Could I still pop my laptop down and connect it and use the 27" display along with one of the Dell displays and the MBP display? Any suggestions for the best setup?
