The "Smart M7 - M70D" monitor does not support direct screen mirroring via WLAN from an iPhone. For screen mirroring, you usually need a Smart TV function or a special app such as AirBeamTV that runs on a Smart TV. As this monitor does not have Smart TV functions, direct screen mirroring via Wi-Fi is not possible. However, you could try using an HDMI adapter or another physical connection to transmit the screen.
