iPhone 15: DisplayPort Support, Pro Comparison, Underrated Upgrade, Rumor Report Card, and User Backlash
All models of the iPhone 15, including the iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max, now support DisplayPort for up to 4K HDR video output to an external display or TV. This feature is made possible through the USB-C port on the devices, allowing for native 4K/60Hz video output to a DisplayPort-equipped display with a compatible cable. Alternatively, users can utilize Apple's USB-C Digital AV Multiport Adapter to mirror video to an HDMI-equipped display, although HDR is not supported in this case. Previous iPhones with a Lightning port were limited to 1080p video mirroring.
