iPhone 12 Pro might come with 120Hz display as seen on iOS 14 developer preview

Yesterday, Apple has announced the new update to macOS Big Sur, iPad OS and iOS 14. The iOS 14 developer preview has an additional function to limited 60 fps which hints the next iPhone flagship might be able to support display higher than 60Hz.

This settings can be found on Settings > Accessibility > Motion and it is named as “Limit Frame Rate”. Once enabled, the refresh rate/ frame rate will be limit to 60fps.

As for the current iPhone 11 Pro Max, the maximum refresh rate is only at 60Hz. This could mean the future of iPhone flagship might have display rate higher than 60Hz, or at 120Hz.
