Im looking at purchasing a display and I'm torn between the P2715Q (4K) and the Apple Thunderbolt Display. As of this moment I'm leaning more towards the P2715Q. In the past I purchased a Dell U2313HM and it was returned due to the aggressive ag coating, dirty white's appearance and yellow tingling. So I'm a bit apprehensive about buying another Dell Display. I do appreciate that the Dell P2715Q is a completely different monitor from the last Dell monitor owned, can anyone advise who have / had this monitor if it is free from yellow tinge etc. Also, I like the sharp fonts displayed on my Retina MacBook / iPad and having used Thunderbolt Display in the past I'm now pondering if I would be unsatisfied using the Thunderbolt Display having become accustomed to the sharp text on my MBPr and iPad. The Thunderbolt Display that was released circa 2011, I'm not to fussed about the USB 2.0 ports, though I do like the connectivity that it has for the MBPr and the built in speakers and camera. My main use for the monitor is for Web Development, my MacBook Retina 15" is the late 2013 that supports 4K at 60mhz as far as I believe.
