Screen Mirror your Samsung TV to your Galaxy phone | Samsung US

Your Samsung Galaxy phone works in concert with your TV to display media and play video on a larger screen. When you're in another room, open Quick Settings and tap Smart View to share your screen to your TV. Now, tap the device you want to share with, and your phone screen will mirror to the TV.
You can adjust screen mirroring options such as aspect ratio while mirroring.
Depending on your TV model, you can set up screen mirroring in a few configurations.
You can also display your TV display on your phone - even if you aren’t in the room. Open Quick Settings and tap on Smart View. Scroll down and select Other Device Phone, and select the TV from the list. Enjoy your TV programs from anywhere in your wireless network!
