1. Connect with Smart View
This is the most basic method of mirroring your Samsung smartphone to a TV through Wi-Fi. On your LG TV, use the remote to press the Menu or Recents button and look for the Screenshare option on the menu. Ensure that both the phone and TV are on the same WiFi network. After this point, the next steps apply to both Samsung and LG smart TVs.

Step 2. Select your TV from the list of available devices (depending on the TV, you may need to enter a PIN).

If the mirroring image is small on the screen, you can change the aspect ratio.
Step 1. Go to Smart View > Tap on More Options (three vertical dots).
