The panel itself also appears to have dual domain pixels and a conventional RGB stripe. Viewing angles as a result are quite good. The cover glass also contains the AR coating first introduced with the iPad Air 2, which cuts reflectance roughly in half relative to a display that doesn’t have such a coating. This effectively doubles outdoor contrast, so it’s great for outdoor use.
You want a display to have as little reflectance as possible. Here are some test results:
- Brightness: 426.71 nits (max). The iPad Pro came in the middle of the pack, with the iPhone 6s Plus at #1 with 582.01, and just ahead of the iPad Air 2 at 406.99.
- Black Levels: 0.25 nits. The iPad Pro was #1 followed by NVIDIA’s SHIELD (0.29) and Microsoft’s Surface Pro 4 (0.30).
- Contrast Ratio: 1,644. The iPad Pro was #1 followed by Huawei Mate 8 (1,607) and iPhone 6s (1,532).
- White Point: 6,908K. 6500K is optimal. The Google Nexus 5X (6,541K) and Samsung Galaxy Tab S2 (6,466K) were the closest.
- Grayscale Accuracy: 1.80 (average DeltaE 2000). The iPad Pro came behind the iPad mini 4 (1.02), Google Nexus 5X (1.38), and Surface Pro 4 (1.80).
- Saturation Accuracy: 1.37 (average DeltaE 2000). Similar to grayscale accuracy, the iPad Pro came in at #4 behind the iPad mini 4 (0.87), Surface Pro 4 (1.34), and Google Nexus 5X (1.35).
- Gretag MacBeth (GMB) Accuracy: 1.55 (average DeltaE 2000). Second only to the iPad mini 4 (1.32), with the Surface Pro 4 (1.56) and Google Nexus 5X (1.65) right behind.
AnandTech concludes by stating the iPad Pro display as “one of the best available on the market today.”
