Screen mirroring is a way to cast content from one device to another. This lets you enjoy that content on a larger display such as a TV or monitor. Most smart entertainment devices allow you to do this, but native casting isn’t supported by all content sources.
Whether you want to watch Netflix, Hulu, or Prime, view your work on a larger display or deliver a presentation to others in the room, screen mirroring from your Mac makes it easy.
How To Mirror Your Mac Laptop To a PC Monitor Using a Cable (Direct Wired)
Connecting your laptop to a PC monitor directly is the old-fashioned way to mirror your Mac to a PC monitor. If you have a Lightning to VGA adapter for your Mac, connect it to the monitor, and then use the steps below to mirror your Mac’s screen.
- Check the ports on your Mac, as these will determine whether you’ll need an adapter or not. You’ll need to use an adapter in cases where the cable from your external device isn’t compatible with the USB-C or Thunderbolt 3 port on your Mac. You can find the right adapter or cable for your Mac by identifying the connector on the end of the cable from your display.
- Next, check the number of displays your Mac supports. To do this, click on the Apple menu and select About This Mac.
- Click Support > Specifications. On the web page that appears, go to the Video Support section to see the number of displays your Mac supports.
4. On your Mac, click the Apple logo to open the menu and select System Preferences.
5. Click Displays.
6. Next, click Arrangement.
7. Click on the checkbox next to Mirror Displays to select it.
Note: You don’t need to have your Mac laptop’s native display open to using the external monitor (also known as closed-display mode or closed-clamshell mode). If you have an external mouse or keyboard, you can use them with the external monitor. However, if you need the keyboard on your laptop, you’ll have to keep the laptop open.
In the Arrangement tab, you can arrange your displays, or change the primary display, and move displays to the position you want. A red border will appear around the display whenever you change its position.
To set your PC monitor as the primary display, just drag the menu to that display.
