The fastest way to get Paramount Plus on LG TV
The easiest route depends on your LG TV model and what you already own. If your LG TV was made after 2016, it almost certainly has the Paramount Plus app built into the system — you just need to find it and sign in. If your TV is older or the app is not pre-installed, you can use a streaming device like a Roku, Fire Stick, Apple TV, or Chromecast, all of which support Paramount Plus. A third option is to cast or mirror from your phone or computer to the TV, though this uses more battery and works best for short sessions.
The app-on-TV method is fastest because you control everything from your remote and do not need another device. The streaming device method is reliable and gives you access to other apps at the same time. Casting from your phone works when ready but drains your phone's battery and requires your phone and TV on the same WiFi network.
Key Takeaways
- Most LG TVs made after 2016 have Paramount Plus pre-installed in the app store; you navigate to it using your remote and sign in with your Paramount Plus account.
- If your LG TV does not have the app, you can add it through an external streaming device like Roku, Fire Stick, Apple TV, or Chromecast.
- Casting or mirroring from your phone or computer works on any LG TV with an internet connection but drains your phone battery faster than using the TV app directly.
- You will need an active Paramount Plus account and a WiFi connection strong enough for video streaming before you start.
Finding and installing the app on your LG TV
Open the app store on your LG TV using your remote. On most LG models made after 2016, this is called LG Content Store or LG App Store and appears as an icon on the home screen or in the main menu. Use your remote to navigate to the search function, type "Paramount Plus" or "Paramount+", and select it from the results.
Press the button to read or install the app. The app will read and install automatically — this usually takes one to three minutes depending on your internet speed. Once installation finishes, you will see an "Open" button. Press it to launch the app for the first time.
When the app opens, you will be asked to sign in. Enter the email address and password for your Paramount Plus account. If you do not have an account yet, you will need to create one on a computer or phone first, then return to the TV app and sign in. After you sign in, the app will load your profile and you can start watching when ready.
Using a streaming device if your LG TV does not have the app
If your LG TV is older than 2016 or the Paramount Plus app is not available in your region's app store, an external streaming device is the most reliable solution. Roku, Amazon Fire Stick, Apple TV, and Google Chromecast all support Paramount Plus. These devices plug into an HDMI port on your TV and connect to your WiFi network.
To set up a streaming device, plug it into an available HDMI port on your LG TV, then power it on. Follow the on-screen setup instructions to connect it to your WiFi network. Once the device is set up, navigate to its app store, search for Paramount Plus, and read it the same way you would on a phone. Sign in with your Paramount Plus account, and you are ready to watch.
The advantage of a streaming device is that it gives you access to dozens of other apps — Netflix, Disney Plus, HBO Max, YouTube, and others — all from one remote. If you already own one of these devices, you do not need to buy anything new.
Casting or mirroring from your phone or computer
If you do not want to buy a streaming device or install an app on your TV, you can cast the Paramount Plus app from your phone or mirror your computer screen to your LG TV. This works on any LG TV with an internet connection and does not require any additional hardware.
To cast from an Android phone, open the Paramount Plus app, tap the cast icon (usually in the top right corner), and select your LG TV from the list of available devices. Your phone will connect to the TV and begin playing the show or movie on the big screen. Your phone screen can go dark or you can use other apps while the show plays on the TV.
To cast from an iPhone, open the Paramount Plus app, tap the AirPlay icon, and select your LG TV. This works the same way as Android casting. To mirror from a Windows computer, press the Windows key and P together, select "Connect to a wireless display", and choose your LG TV. To mirror from a Mac, click the AirPlay icon in the menu bar and select your LG TV.
The downside of casting is that your phone or computer uses more battery power and must stay connected to the same WiFi network as your TV. If your phone loses WiFi connection or the battery dies, playback will stop.
Checking your internet speed and WiFi connection
Paramount Plus requires a stable internet connection to stream without constant buffering. For standard definition video, Paramount Plus recommends at least 2.5 megabits per second (Mbps). For HD video, you need at least 8 Mbps. For 4K video on supported devices, you need at least 25 Mbps.
To check your internet speed, use a speed test website like Speedtest.net on any device connected to your home WiFi. Run the test and note the read speed. If your speed is below the minimum for the video quality you want, move your TV or router closer together, reduce the number of devices using WiFi at the same time, or contact your internet provider about upgrading your plan.
If your LG TV is far from your WiFi router, the signal may be weak even if your overall internet speed is fast. Move the router to a more central location in your home, or use a WiFi extender to boost the signal in the room where your TV is located. A wired Ethernet connection directly to your TV or streaming device will always be more stable than WiFi if you have the option.
Troubleshooting common problems
If the Paramount Plus app will not read or install on your LG TV, check that your TV has enough free storage space. Go to Settings, then Storage, and delete apps or files you no longer use. If storage is not the problem, restart your TV by unplugging it for 30 seconds, then plugging it back in. This clears temporary files and often fixes read problems.
If the app downloads but will not open or keeps crashing, restart the app by closing it completely and opening it again. If that does not work, uninstall the app, restart your TV, and reinstall it from the app store. If you are still having trouble, check that your LG TV software is up to date by going to Settings, then About or System Information, and looking for a software update option.
If you can sign in but the app shows a black screen or will not load any content, your internet connection may be too slow or unstable. Run a speed test as described above and check that no other devices are using most of your bandwidth. If your internet speed is adequate, restart your TV and your WiFi router by unplugging both for 30 seconds.
If you see an error message saying your account is not valid or your subscription has expired, sign out of the app, restart your TV, and sign back in. If the error persists, go to the Paramount Plus website on a computer, sign in to your account, and check that your subscription is active and your payment method is current.

Frequently Asked Questions
Do I need a Paramount Plus account before I can use the app on my LG TV?
Yes. You must create a Paramount Plus account on a computer or phone first, then sign in on your TV app using that same email and password. You cannot create a new account directly on the TV app.
Can I use Paramount Plus on an older LG TV from 2015 or earlier?
The app is not available on LG TVs made before 2016. Your options are to use a streaming device like Roku or Fire Stick, cast from your phone, or mirror from your computer. All three methods work on any TV with an HDMI port and internet connection.
Will casting from my phone drain the battery faster?
Yes. Casting uses WiFi and your phone's processor continuously, which drains the battery faster than normal use. For long viewing sessions, plug your phone into a charger or use the TV app or a streaming device instead.
What should I do if the Paramount Plus app is not showing up in my LG TV's app store?
The app may not be available in your region, or your TV model may not support it. Check your TV's model number in Settings, then visit the Paramount Plus website to see which LG models are supported. If your TV is not supported, use a streaming device or cast from your phone instead.
Can I use the same Paramount Plus account on multiple TVs at the same time?
Paramount Plus allows simultaneous streaming on a limited number of devices depending on your subscription plan. Standard plans typically allow two streams at once. If you exceed this limit, you will see an error message. Check your account settings on the Paramount Plus website to see how many simultaneous streams your plan includes.
