How does Apple connect the projector?

1. First, connect the external monitor to the power supply, and connect the data cable to the MAC through the adapter (Apple notebook computer only has USB-C interface or DisplayPort interface, so it needs to be connected through the adapter).

2. After the connection is completed, the system will automatically recognize it, open the system preferences on the Apple computer and enter the display settings.

3. Then, after entering the display option, we can see two screen settings pages, in which the resolution and other related settings are automatically optimized by the Mac without manual setting.

4. If the external projector of Mac is used for the first time, the external display will not project the contents displayed on the Mac screen, which is a unique "arrangement" display function of Mac. Equivalent to the "extended" mode of Windows system.

5. Select "Mirror Display" in the picture to keep the display content of Apple laptop and projector synchronized.

6. That's it.
