There’s actually not that much new with the iPhone 15 Pro Max’s display, with the exception of thinner bezels around the 6.7-inch OLED panel. Apple says you still get 1,600 nits of peak brightness and 2,000 nits outdoors.

The ProMotion display continues to offer 120Hz refresh rates, so you get smooth scrolling and animations. And with the always-on display, you can still check notifications, the time and more without having to unlock your iPhone.

I also continue to appreciate the Dynamic Island. It’s easy to get real-time updates at the top of the display, such as the status of my Uber ride, my United flight status or easy access to my Spotify playlist.

In our test results, the Pro Max hit a max of 1,550 nits when playing HDR content, which is about the same as the iPhone 14 Pro Max. The Galaxy S23 Ultra was a slightly dimmer 1,444 nits on the same test.

Color reproduction remains strong on this panel, which I noticed when watching the trailer for Aquaman 2. The underwater world’s colors looked vibrant and the details on Jason Momoa’s gleaming costume sharp.

In our testing the iPhone 15 Pro Max reproduced 119.4 % of the sRGB color gamut and 84.5% of the more demanding DCI-P3 color space. The Galaxy S23 Ultra hit a lower 111.2% / 78.8 % in Natural mode but a higher 193% / 136.7% in Vivid mode.

The iPhone 15 Pro Max’s display offers more accurate colors, as it earned a Delta-E score of 0.14 (where zero is perfect). The S23 Ultra notched 0.3.
