Notes:

  1. The first available screen to mirror to is automatically selected.
  2. If you are unable to find your TV on the list of available devices to connect Mac to LG Smart TV shown in the menu, make sure the device is switched on. Also, it needs to share the same internet network as your Macbook. If that’s the case, click on the Refresh button in the menu to update the device list.
  3. When mirroring begins, the content of your Mac screen will be displayed on the TV screen.
  4. Click on the Stop Streaming option to stop mirroring.
  5. Screen mirroring settings are available in the Mirroring tab under Preferences.

Screen mirroring doesn’t include sound. If you’d like to add sound, you have to install the JustStream Audio Driver, which comes with the JustStream installer.

How to connect Mac to LG TV with Apple TV

If you have an Apple TV, it gives you another convenient way to connect Macbook to LG smart TV wirelessly.

By plugging an Apple TV into your TV via HDMI, you can then use AirPlay to connect your Mac to your television. This means you can stream content from your Macbook or share your screen with the TV, or use Apple TV’s built-in capabilities to directly stream other web content.

Follow these steps to share your Mac or MacBook screen with your TV using the Apple TV:

  1. Plug your Apple TV into an HDMI port on the back of your TV set.
  2. Ensure your Apple TV and Mac are connected to the same WiFi network. The connection won’t work unless there is a WiFi network available.
  3. On your Mac, click on the AirPlay button in your menu at the top of your screen (a rectangle with an arrow pointing up).
  4. Find your Apple TV under AirPlay 2 and click on it. (It may be named after the room it is located in, for example).
  5. Your screen will now be mirrored to the TV. You can change the resolution and other settings by going to System Preferences.
  6. If you’d like to use your TV as a second display, go to System Preferences > Displays > Arrangement, then deselect Mirror Displays. This means the two displays will no longer look the same.
  7. To make further changes easier, you can tick the box beside Show mirroring options in the menu bar when it becomes available. After that, you will be able to make such changes simply by clicking on the AirPlay icon in the menu.
