A fresh rumor from reliable Apple leaker Majin Bu has us looking at iOS 19 with a little more anticipation, especially if you’re someone who’s ever plugged your iPhone into an external monitor and wished it could do more than just mirror your screen.
iOS 19 Could Let iPhone Users Extend Their Display to External Monitors
According to Bu, iOS 19 will introduce a Stage Manager-style interface for iPhones with USB-C, meaning likely the iPhone 15 series and newer.
Instead of basic screen mirroring, this update could let users extend their display, offering real multitasking functionality: multiple apps visible at once, dedicated windows, and more space to work with.
It’s not a full desktop mode, but for tasks like presentations, video editing, or side-by-side app usage, it could be a major leap.

Just in Time for the New Apple Studio
The timing feels calculated. Rumors also point to a new Apple Studio Display launching around the same time as iOS 19, suggesting Apple may be prepping to pitch the iPhone as part of a broader productivity ecosystem.
While nothing is official yet, this rumored update would mark the first time the iPhone supports an external display in a way that feels genuinely useful for power users, and not just a novelty.
