Method #2: Using a Wireless Connection

  2. Click “System”.
  3. Click “Display”.
  4. Click “Connect to a wireless display”.
  5. Select your TV from the list and click “OK”.

Your smart TV is turned into a monitor. Now, you can work on your computer and see the contents on your TV. 

Keep in Mind

If you don’t see your smart TV under the “Connect to a wireless display” list, click the “Detect” button under the “Multiple Displays” header option. 

Method #3: Using AirPlay on Mac Computer

You can quickly turn your TV into a monitor by connecting your Mac computer to it through AirPlay. However, you need to ensure that you have either an Apple TV streaming device or an AirPlay 2-enabled smart TV.

Here is the complete method to mirror your Mac laptop screen on your TV through AirPlay.

If you don’t want to mirror your Mac screen to your TV anymore, click “Screen Mirroring” and “Stop Mirroring”.

Method #4: Using Chromecast With Chromebook

If you are a Chromebook user, you can wirelessly cast your TV with a Google Chromecast device and turn it into a monitor. You don’t have to invest in an HDMI cable, which will be a cleaner setup. 

Before going through this method, ensure that your TV and Chromebook are connected to the same internet connection. 

  1. Plug your Google Chromecast device into the HDMI port at the back or side of your TV.

  3. Choose the HDMI port where the Chromecast device is plugged.
  4. On your Chromebook, click “Time” and ensure “Bluetooth” and “Wi-Fi” options are turned on.
  5. Click “Cast devices available”.
  6. Select the content you want to cast to your TV screen (i.e., desktop).
  7. Click “Share”.

Your Chromebook will now cast the screen to your TV. If you want to stop sharing your Chromebook screen on your TV, click “Time” and “Stop” next to the “Casting Screen” option. 

Keep in Mind

It is possible to cast Windows desktop to your TV on any computer. To do this, launch Chrome, click the three dots (menu icon), click “Cast” > “Sources” > “Cast Desktop”, and select your TV from the list.
