Jayluv36,

Thanks so much for posting your question here in the Xfinity Forum. Currently, we provide the Xfinity Stream Beta app on the following LG Smart TVs:

• 2019 TVs with Model Codes LG SM, LG UM, LG LM, LG OLED *9.
• 2018 TVs with Model Codes LG SK, LG UK, LG LK, LG OLED *8.
• 2017 TVs with Model Codes LG SJ, LG UJ, LG LJ, LG OLED *7.

Follow these steps to determine your LG TV model and software version:

The model number can be found on the back of your LG Smart TV. You can also find it by pressing the Home button on your remote and selecting Settings (Gear icon), then scrolling over to About This TV under General.

Next, follow these steps to add the Xfinity Stream Beta app to your compatible LG Smart TV:

1. Make sure your LG Smart TV is connected to the Internet.
2. Press the Home button on your remote to bring up the main menu.
3. Scroll right or left until you reach the LG Content Store.
4. Select Apps & Games at the top of the page.
5. Select the Xfinity Stream Beta app.
6. Click Install.
7. Once the installation is complete, select Launch to start using the Xfinity Stream Beta app.
8. When asked, register your device and sign in with your Xfinity credentials.

Activation

1. Launch the app from either the Samsung Hub app store or the LG Content store. If your Smart TV hasn't been activated, you'll see the Welcome screen. Select Get Started to continue. If your Smart TV has already been activated, you'll see the main menu.
    
2. The Activation Code screen will appear on your Samsung or LG Smart TV. On another device (like a mobile phone, tablet or laptop - not from your Smart TV), go to xfinity.com/authorize to continue the activation process.
    
3. From the web browser on your second device (not the Smart TV), enter the six-digit code provided from the Xfinity Stream Beta app.
    
4. Still, from the web browser, enter your Xfinity username and password, then select Sign In.
    
5. The web browser will show a Success! message, notifying you that your Samsung or LG Smart TV has been activated and the activation screen on the Xfinity Stream Beta app will update shortly.
    
6. After your Smart TV has been successfully activated, you'll see the Terms of Activation. Scroll to read the terms and select Yes to accept and continue. If you select No Thanks, you'll be taken back to the first step of the activation process (Welcome screen).
   
    
7. Next, name your device and select Confirm. The device name is used to help with troubleshooting as well as any future device management settings.
   
    
8. You'll see the main menu. You're ready to begin using the app!
