iPhone 15 charging cable, display port?
Want to know if the cable that came with my iPhone 15 will work to connect my laptop (which has a usb c port) to an external display (with a usb c port).
Question marked as
Does this laptop's USB-C port support video output?
Not all external display support USB-C for video input. Typically, they would have HDMI, miniDisplayPort, or DisplayPort connections. Older ones would have DVI and/or VGA. Only the most recent ones now come with USB-C for video input. It's important to verify what capability your monitor's USB-C ports are designed for.
If you verified that your display does support USB-C video input, then your iPhone's USB-C cable should work.
