Hello! Which external displays with retina feeling do you guys think is the best for rMBP 15" mid 2015, 2880×1800 (16:10) 220 ppi ? I am a newbie on this, but I prefer 19-23 inch and not small text. The LG Ultrafine 4k 21.5" 220 ppi (link) is not supported ! Tested DELL U2515H 25" 2560x1440, 117 ppi (link), but didn't like it at all, to small text and no retina feeling. What about DELL P2016 19.5" 1440x900, 87 ppi (link). Half resolution but wrong ppi. Thank you!!
