Every iPhone device has a predefined screen resolution that cannot be changes with convenient methods. ResSet16 is a new tool allowing users to set screen resolution on iOS 15 – iOS 16 to anything you like. What's more, it doesn't require a jailbreak to work.

What is ResSet16?

ResSet16 is a handy tool that lets you alter the screen resolution of your jailed iPhone or iPad running iOS 15 to iOS 16.1.2. Although modifying the screen resolution is discouraged and blocked by Apple, there may be instances where it proves useful.

To use ResSet16, simply sideload the IPA onto your device and launch the app from the Home Screen. The app boasts a user-friendly interface, enabling you to modify your device's screen resolution using the MacDirtyCow exploit. To undo any changes, simply reboot your device.

ResSet16 is influenced by ResolutionSetterSwift for TrollStore but leverages the MacDirtyCow exploit for greater device and iOS compatibility. The tool supports all iOS versions from iOS 15 to iOS 16.1.2 (excluding iOS 15.7.2 and iOS 15.7.3). Use it to set screen resolution on iOS 15 - iOS 16.

Tip: Users have suggested using Pro Max resolutions on smaller Pro devices for an improved aesthetic appearance. Other resolutions may result in an goofy appearance.

If you are interested Matthew Anisovich released ResSet16 as an open source project under GPL-3.0 license, with source code made available through GitHub Repository. ResSet16 is absolutely safe to use, and all changes can be reverted by force restarting your iDevice.

ResSet16 was developed using a blend of Objective-C, C, and Swift programming languages and is frequently updated by the developer. As of February 2, 2023, the latest version of the ResSet16 IPA has been released and future updates are planned to address known issues.
