Hello, I can't make up my mind between these following three Dell displays. I hope someone could help me out. 1) 2X Dell U2415 = 444 Euros 2) 1X Dell U2715H = 400 Euros 3) 1X Dell U2414Q = 480 Euros I have the high end late 2013 15" rMBP and use it for web and iOS development. Currently using an old 24 inch Samsung (Full HD) display as a second monitor, but it's due for replacement. At work I use 2 24 inch Full HD Dell displays, which works great. I've never used a 27 inch monitor or a 4K monitor before, so I don't know how the experience will be using any of those two for development. I hope someone could share his/her experience with me so I can finally make up my mind.
