The portable monitor is compatible with the iPhone 13 Pro if you use the appropriate connection adapters, as it supports HDMI and USB-C video inputs. The iPhone 13 Pro does not have a native HDMI or USB-C video output, so you would need a Lightning to HDMI adapter or a Lightning to USB-C adapter that supports video output to connect the phone to the monitor. The monitor has a Full HD (1920 x 1080) resolution and supports HDR, which the iPhone 13 Pro can output via compatible adapters.
