I want to get an external monitor for my MBP15 early 2013 model. Being limited to 2560x1600 I dont want to spend a lot of $ since I would expect to upgrade in the next couple of years and I will buy a 4k then. So I looked up monitors that can reproduce Adobe RGB and I found these 2 dell U2515H and UP2516D. The 2515 is about $100 cheaper. Which would you pick? Is there another worth considering? Thanks!
