iPhone 17 Pro Max — Screen Size, Resolution & PPI

What these specs mean

At phone viewing distance (around 15 cm / 6 inches), pixel density is the first thing you notice — above 300 PPI individual pixels disappear and text looks printed rather than pixelated. Refresh rate controls how smooth scrolling and games feel: 60 Hz is the long-standing baseline, 90–120 Hz noticeably cuts motion blur, and LTPO OLED panels can ramp from 1 Hz up to 120 Hz to save battery on static content. OLED's per-pixel contrast also makes blacks look genuinely black, which matters for dark-mode reading and overall battery behavior.

Apple uses the Retina brand for any display where pixels aren't resolvable at normal viewing distance; iPhone Pro and iPad Pro lines add ProMotion (adaptive 120 Hz), Super Retina XDR (OLED with per-pixel HDR), or Liquid Retina XDR (mini-LED with thousands of local dimming zones). True Tone automatically shifts white balance to match ambient light.

Frequently asked questions

What is the pixel density of the iPhone 17 Pro Max?

The iPhone 17 Pro Max has a 460 PPI pixel density on its 6.9-inch display — high enough that individual pixels are indistinguishable at typical viewing distance. Combined with the screen's LTPO OLED technology, this determines how sharp text and images actually render.

When was the iPhone 17 Pro Max released?

Apple launched the iPhone 17 Pro Max in Sep 2025. Release date matters when checking software support windows: most manufacturers commit 5–7 years of security updates and 3–5 years of major OS upgrades from launch.

What operating system does the iPhone 17 Pro Max run?

The iPhone 17 Pro Max ships with iOS. Apple typically delivers OS updates over-the-air — check the device's Settings app or Apple's support page for the latest available version.
