The fastest way to watch YouTube on your smart TV
Most smart TVs come with YouTube already built in. Open your TV's app store (called the Play Store on Android TVs, the App Store on Samsung or LG TVs, or the Prime Video Channels section on Fire TVs), search for YouTube, and install it. If your TV is made by Samsung, LG, Sony, TCL, Roku, or Amazon, YouTube is often pre-installed—just look for the YouTube icon on your home screen.
If your TV doesn't have YouTube built in, or if you want to use a different device, you can cast YouTube from your phone or computer to your TV using a streaming device. The most common options are Google Chromecast, Amazon Fire Stick, Roku, or Apple TV. Plug the device into an HDMI port on your TV, connect it to your Wi-Fi, and you can then send YouTube from your phone to the device with a single tap.
The method you choose depends on what TV you own and whether you already have a streaming device. All three routes—built-in apps, casting from your phone, and external devices—work equally well for watching YouTube on a television.
Key Takeaways
- Most modern smart TVs have YouTube pre-installed or available free in the TV's app store.
- You can cast YouTube from your phone to any smart TV using Google Chromecast, Roku, Fire Stick, or Apple TV.
- Built-in YouTube apps work best if your TV is from Samsung, LG, Sony, TCL, Roku, or Amazon.
- Casting from your phone lets you control playback from your phone screen while the video plays on the TV.
Installing YouTube directly on your smart TV
If your TV runs Android TV (common on Sony, TCL, and some Philips models), open the Play Store app on your TV remote, search for YouTube, and select Install. The app downloads and appears on your home screen within seconds. You then sign in with your Google account to access your subscriptions and watch history.
If your TV is a Samsung, LG, or Panasonic model, the process is similar but the app store has a different name. Samsung calls it the Samsung App Store or SmartThings app store. LG calls it the LG Content Store. Search for YouTube in whichever store your TV uses, install it, and sign in. The YouTube app will then appear as a tile on your TV's home screen.
If you own a Roku TV or Fire TV, YouTube comes pre-installed on most models made after 2015. Look for the YouTube icon on your home screen—it's the red play button. If you don't see it, go to the Roku Channel Store or Amazon Appstore, search YouTube, and install it. Signing in with your Google account takes about one minute.
After installation, you control YouTube using your TV remote. Most TV remotes have a microphone button that lets you search by voice—just press it and say the video title or channel name you want to watch.
Casting YouTube from your phone to your TV
Casting sends YouTube from your phone or tablet to your TV without needing an app installed on the TV itself. This works if your TV has a casting receiver built in (most smart TVs made after 2016) or if you plug in a Chromecast device, Fire Stick, Roku, or Apple TV.
To cast from an iPhone or Android phone, open the YouTube app, tap the cast icon (it looks like a rectangle with a Wi-Fi symbol in the corner), and select your TV from the list. The video starts playing on your TV, and you control it from your phone—pause, rewind, change volume, or switch videos all from your phone screen. Your phone screen can stay on or go dark; the video keeps playing on the TV.
Casting works best when your phone and TV are on the same Wi-Fi network. If they're on different networks, casting usually won't find your TV. Restart your router and TV if the cast button doesn't show your TV in the list.
Using a streaming device if your TV doesn't have YouTube
If your TV is older or doesn't have a built-in app store, plug a streaming device into an HDMI port on the back of your TV. The most common options are Google Chromecast with Google TV, Amazon Fire TV Stick, Roku Streaming Stick, or Apple TV. Each device costs between $30 and $150 depending on the model.
After plugging in the device, connect it to your Wi-Fi using the on-screen setup menu. The device will guide you through signing in with a Google account (for Chromecast and some Roku models) or an Amazon account (for Fire Stick). Once signed in, you'll see YouTube as one of the available apps on the home screen. Select it, and YouTube opens just like it would on a smart TV.
Streaming devices also let you cast from your phone, so you get both options—you can use the remote to navigate YouTube on the TV, or tap the cast button on your phone to send a video to the TV. Most people use the remote for browsing and the phone for quick casting.
Connecting to Wi-Fi and signing in
YouTube requires an internet connection and a Google account. When you first open YouTube on your TV, you'll see a sign-in screen with a code and a website address. Go to that website on your phone or computer, enter the code, and sign in with your Google account. The TV recognizes the sign-in and loads your subscriptions, watch history, and recommendations within a few seconds.
If your TV loses Wi-Fi connection, YouTube will pause and show an error message. Restart your router and TV if this happens. Most smart TVs remember your Wi-Fi password, so you won't have to enter it again after the first time.
If you share a TV with other people, each person can sign in with their own Google account. The TV will remember multiple accounts and let you switch between them from the YouTube home screen. This keeps everyone's watch history and recommendations separate.
Troubleshooting common problems
If the YouTube app won't install, check that your TV has enough storage space. Go to your TV's Settings menu, find Storage, and look for available space. If you have less than 500 MB free, delete an unused app to make room. Then try installing YouTube again.
If YouTube loads but videos won't play, your TV's internet connection is probably too slow. Move your TV closer to your Wi-Fi router, or restart both the TV and the router. If videos still buffer, your internet speed may be below 5 Mbps—contact your internet provider to check your connection speed.
If the cast button doesn't appear in the YouTube app on your phone, make sure your phone and TV are on the same Wi-Fi network. If they are, restart the YouTube app on your phone. If the cast button still doesn't appear, restart your phone and TV.
If you see a message that says "This video isn't available on this TV," the video may be restricted by the content creator or may only be available in certain countries. Try searching for a different video to confirm YouTube is working.
