Connect the adapter to your phone using a USB cable and connect the VGA cable to the projector. Then switch the projector source to VGA and your phone screen should appear on the projector.

5. Connect using a wireless display adapter
If you prefer a wireless connection, you can use a wireless display adapter like the Microsoft Wireless Display Adapter to connect your phone to the projector. Connect the adapter to the projector and use your phone to connect to the adapter via Bluetooth. Then, simply select the adapter from the list of available devices and your phones screen will appear on the projector.

In conclusion, connecting your phone to a projector without wifi is not as complicated as it seems.
