If you’re looking for a way to increase the screen real estate of your MacBook, or you simply want to use an external display as your main monitor, you can do so by connecting your MacBook to an external monitor. This process is relatively simple, and in most cases only requires a few minutes to complete.
In order to connect your MacBook to an external monitor, you will need the following items:
- A Mini DisplayPort to DVI Adapter (or a Mini DisplayPort to VGA Adapter)
- A DVI or VGA cable
- An external monitor
Once you have gathered the necessary items, follow the steps below to connect your MacBook to an external monitor:
- Connect the Mini DisplayPort end of the adapter to the Thunderbolt port on your MacBook.
- Connect the DVI or VGA end of the cable to the adapter.
- Connect the other end of the DVI or VGA cable to the external monitor.
- Turn on the external monitor.
- On your MacBook, open System Preferences and click on “Displays”.
- In the “Display” tab, select the “Arrangement” tab.
- In the “Arrangement” tab, you will see a representation of your MacBook’s screen and the external monitor. If the external monitor is not showing up, make sure that the “Mirror Displays” checkbox is not selected.
- Once the external monitor is showing up in the “Arrangement” tab, you can drag the white bar to the external monitor to set it as your primary display. You can also adjust the resolution of the external monitor by clicking on the “Scaled” radio button and selecting a resolution from the drop-down menu.
- When you are finished, close System Preferences and your MacBook’s screen will be transferred to the external monitor.
If you want to disconnect your MacBook from the external monitor, simply unplug the cable from the monitor or the adapter. You can also disconnect your MacBook from the external monitor by opening System Preferences and clicking on the “Displays” icon. In the “Display” tab, select the “Arrangement” tab and click on the “Detect Displays” button. This will cause your MacBook’s screen to be transferred back to the built-in display.
