Apple's new iPhone Air boasts impressive specs like the A19 Pro chip, a 48MP camera, and a 6.5-inch ProMotion display, but it falls short in supporting AR glasses due to a critical port limitation.

The device's USB-C port lacks DisplayPort support, which is essential for transmitting video signals to AR glasses, making it incompatible with popular AR devices such as Xreal and Viture.

This is primarily because the iPhone Air uses a USB 2 port that does not support DisplayPort Alt Mode, a necessary feature for AR connectivity.

While other devices like the Nintendo Switch 2 have found workarounds through firmware updates and docking stations, such solutions are less practical for the iPhone Air, which does not support video output via its port.

Notably, recent iPhones like the iPhone 16 and iPhone 17 do support DisplayPort on their USB-C ports, making the iPhone Air's restriction a unique and disappointing anomaly.

This port limitation could be addressed if Apple releases Apple Glasses that require DP support, but currently, it remains a significant gap that could impact the device's appeal among AR enthusiasts.
