One of the main features of iPadOS 16 is the new Stage Manager. Front-end scheduling is a brand-new multitasking method, the size of the window can be flexibly adjusted according to your needs, and multiple windows can be stacked in the same view.
You can also connect an iPad Pro or iPad Air to an external monitor through “Pre-stage Scheduling” to achieve up to 6K resolution. The iPad display and an external monitor can display multiple apps together, and files and apps can be dragged and dropped between the two screens.
To the disappointment of some users, the pre-stage scheduling is limited to iPads with the M1 chip, including the latest iPad Pro and iPad Air. In a statement, Apple explained the reason for the M1-only iPad.
Front Office Scheduling is a completely coherent experience that provides a new window management experience that is astonishingly fast and responsive, allowing users to run up to 8 apps simultaneously on iPad and external monitors with resolutions up to 6K. Delivering this experience requires a lot of memory, ultra-fast storage, and flexible external monitor I/O, and for that, the M1 chip is needed.
The M1 iPad Pro comes with 16GB of RAM, while the previous-generation iPad Pro only had 6GB of RAM. At the same time, the storage speed of the M1 iPad Pro is also twice that of the previous generation.
