IPad Pro comes with two screen size options. Both have a 4: 3 aspect ratio. The 12.9-inch is a 2732x2048 Retina display at 264ppi. That’s the largest iOS display Apple has ever shipped. Though it’s not quite as dense as iPad mini, and much less than iPhone 7 Plus, the larger size means you’ll likely hold it slightly further away, making it effectively equal. The panel is LED backlit and boasts in-plane switching ( IPS) technology for improved viewing angles. It’s also laminated with a new anti-glare coating and sports a new variable refresh rate, making it one of Apple’s most advanced displays ever.
The 9.7-inch is a 2048x1536 Retina display at 264ppi. It also features a DCI-P3 wide color gamut, and a True Tone technology that adjusts the color temperature to match ambient light, making it look paper-white.
