Getting YouTube on Your TV Screen

You can watch YouTube on your TV in three main ways: cast from your phone or computer, use a built-in YouTube app on a smart TV, or connect a streaming device like a Roku, Apple TV, or Amazon Fire Stick. The method you choose depends on what equipment you already own and how often you plan to watch. Most modern TVs have YouTube built in, but if yours doesn't, a streaming device is the cheapest way to add it.

The fastest route for most people is casting—sending video from your phone or computer directly to your TV without plugging in cables. This works if your TV supports Google Cast (most Samsung, LG, and Sony TVs made in the last five years do) or if you have a Chromecast device plugged into an HDMI port. Casting takes about 30 seconds to set up the first time and works when ready after that.

Key Takeaways

  • Smart TVs made by Samsung, LG, Sony, and others have YouTube built in—just open the app and sign in with your Google account.
  • Casting from your phone or computer sends YouTube to your TV wirelessly and works on any TV with Google Cast or a Chromecast plugged in.
  • Streaming devices like Roku, Fire Stick, and Apple TV add YouTube to older TVs and cost between $25 and $100 depending on the model.
  • You need a Google account to sign in and watch, and your TV must be connected to the same Wi-Fi network as your phone or computer for casting to work.

Using the YouTube App on a Smart TV

If your TV was made in the last five years and has a smart TV operating system (Samsung Tizen, LG WebOS, Sony Android TV, or similar), YouTube is likely already installed. Look for the YouTube icon on your home screen or in the app menu. If you don't see it, go to your TV's app store—the name varies by brand (Samsung calls it "Samsung Apps," LG calls it "LG Content Store")—search for YouTube, and read it.

Once the app is installed, open it and you'll be asked to sign in. Select "Sign in" and your TV will show a code on the screen. Go to youtube.com/set up on your phone or computer, enter that code, and approve the sign-in. This links your Google account to your TV so YouTube remembers your subscriptions, watch history, and recommendations. After that, you can browse and play videos directly from your TV remote.

The TV remote controls YouTube the same way a phone does: use arrow buttons to navigate, press select to open videos, and use the back button to go to the previous screen. Volume and power buttons work normally. If your remote has a microphone button, you can search by voice—just press it and say what you want to watch.

Casting YouTube from Your Phone or Computer

Casting sends YouTube from your device to your TV over Wi-Fi. Your phone, computer, and TV must all be connected to the same Wi-Fi network. On an iPhone or iPad, open YouTube, tap your profile picture in the top right, tap "Settings," then "Watch on TV." Select your TV from the list and YouTube will start playing on the big screen. Your phone becomes a remote—you can pause, skip, adjust volume, and search without touching the TV.

On an Android phone, open YouTube, tap your profile picture, tap "Settings," then "Connected devices." Select your TV and the video will play there. On a Windows or Mac computer, open YouTube in your web browser, click your profile picture in the top right, and look for "Cast" or a TV icon. Click it, select your TV, and the video will appear on your screen.

Casting stops if you close the YouTube app or turn off your phone, but the video keeps playing on your TV. You can also cast a different video from your phone while one is already playing—it will replace what's on the TV. If casting doesn't work, restart your TV and phone, make sure they're on the same Wi-Fi network, and try again. If your TV doesn't show up in the cast list, it may not support Google Cast; in that case, use a streaming device instead.

Adding YouTube with a Streaming Device

A streaming device plugs into an HDMI port on your TV and adds YouTube and other apps to any television, even older ones without smart features. The most common options are Google Chromecast (around $30), Amazon Fire Stick (around $40), Roku (around $30 to $80 depending on the model), and Apple TV (around $100). All of them have YouTube built in and work the same basic way: plug it in, connect it to Wi-Fi, sign into your Google account, and start watching.

To set up a streaming device, plug it into an HDMI port on your TV, turn on the TV, and switch to that HDMI input using your TV remote. The device will guide you through connecting to Wi-Fi and signing in. Once you're signed in, you'll see the home screen with YouTube and other apps. Select YouTube, and it will open just like it does on a smart TV. You can use the device's remote to navigate, or cast from your phone if the device supports it (Chromecast and Fire Stick do; Roku has its own app).

Troubleshooting Common Casting Problems

If YouTube won't cast to your TV, the most common cause is that your phone and TV are on different Wi-Fi networks. Check that both devices are connected to the same network—look in your phone's Wi-Fi settings and your TV's network settings. If they match and casting still doesn't work, restart both devices: turn off your phone and TV completely, wait 10 seconds, and turn them back on.

If your TV doesn't appear in the cast list at all, it may not support Google Cast. Check your TV's manual or the manufacturer's website to confirm. If it doesn't, you'll need to use a streaming device instead. If you have a streaming device and YouTube won't play, make sure the device is plugged in, connected to Wi-Fi, and that you're signed into your Google account. Unplug the device for 30 seconds, plug it back in, and try again.

If video is choppy or keeps stopping, your Wi-Fi signal may be weak. Move your phone, TV, or router closer together, or restart your router by unplugging it for 30 seconds. If you're far from your router, consider moving the device or upgrading to a router with better range. Video quality also depends on your internet speed—YouTube needs at least 2.5 megabits per second for 720p video and 7 megabits per second for 1080p.

Signing In and Managing Your Account

You need a Google account to watch YouTube on your TV. If you don't have one, go to accounts.google.com on your phone or computer and create one—it's free and takes about five minutes. Once you have an account, sign in on your TV using the method for your setup: enter the code at youtube.com/set up for a smart TV or streaming device, or use your phone to cast.

After you sign in, YouTube will show your subscriptions, watch history, and recommendations on your TV just like it does on your phone. If you want to sign out or switch to a different account, go to the YouTube app settings on your TV. The exact steps vary by TV brand, but usually you go to Settings, then Account, then Sign Out. You can then sign in with a different Google account.

If you share your TV with other people, each person can sign in with their own Google account to see their own subscriptions and recommendations. Some TVs let you switch between accounts without signing out—look in the YouTube app settings to see if your TV supports this.

Frequently Asked Questions

Do I need a YouTube Premium subscription to watch on my TV?

No. YouTube Premium is optional and adds features like ad-free watching and offline downloads, but you can watch YouTube on your TV for free with ads. If you have a Premium subscription on your phone, it will carry over to your TV when you sign in with the same Google account.

Can I watch YouTube on my TV without Wi-Fi?

No. YouTube requires an internet connection, and all methods of getting it on your TV (casting, smart TV apps, streaming devices) need Wi-Fi. You cannot watch YouTube over a cellular connection on your TV.

What if my TV is too old to have YouTube built in?

Buy a streaming device like a Chromecast, Fire Stick, or Roku and plug it into an HDMI port. These devices add YouTube and other apps to any TV made in the last 15 years. Chromecast is the cheapest option at around $30.

Can I use YouTube on my TV without a Google account?

You can browse and watch public videos without signing in, but you won't see your subscriptions, watch history, or recommendations. To get the full experience, you need to sign in with a Google account.

Why does YouTube keep asking me to sign in on my TV?

Your TV may have lost its connection to your Google account, usually because the app was updated or the TV was reset. Go to the YouTube app settings and sign in again using the code method at youtube.com/set up. If this keeps happening, restart your TV and try signing in again.
