Display6.2-inch (6.0-inch with rounded corners) Dynamic AMOLED 2X; 2340 × 1080 (FHD+); adaptive 1–120 Hz; Vision Booster

The adaptive refresh rate drops to 1 Hz on static content to save power; Vision Booster adjusts tone and contrast in bright light.

Typical maximum brightness is 800 nits, with 1200 nits peak for HDR content; typical contrast is 2,000,000:1. The spec page does not list a refresh rate; the Pro models’ ProMotion is not on this model. Because of the rounded corners, the visible area is slightly smaller than a 6.06-inch rectangle.

Apple
Processor10 cores; 3.2 GHz, 2.9 GHz, 2.6 GHz and 1.95 GHz clusters

Samsung notes that the processor varies by market; the US SM-S921U does not use the same chip as this global model.
