Here are four steps you can take to display photos and videos from your phone on a Smart TV:

1. Connect to the same Wi-Fi network: Make sure your phone and TV are both connected to the same Wi-Fi network so the devices can communicate with each other.
2. Visit the Smart TV’s app store or website: Visit the app store or website of your Smart TV and download any necessary applications or extensions that you need to use to access content from your phone.
3. Pair your phone and TV: Use the app or website to pair your phone and TV. This is necessary for the two devices to communicate with each other.
4. Select the photos or videos to be displayed: Select the photos or videos you want to view. You may also be able to stream them directly from your phone.
