In their annual iPad display technology shoot-out, the experts at DisplayMate have compared the new displays of the iPad mini 4 and iPad Pro to 2014's iPad Air 2. The result surprised me:
The nicest surprise this year is the tremendous improvement in the display quality and performance of the iPad mini 4 after the poor showings of previous minis – the mini 4 is now very impressive and breaks many Tablet display performance records. The iPad Pro has also made a strong entrance and first appearance.
If you're into this kind of technical overview, you may want to save a couple of hours to dive deep into this. Incredible research.
