The fastest way depends on what TV and devices you own

You can connect YouTube to your TV in four main ways: cast from your phone or computer using Chromecast or AirPlay, use the YouTube app built into your TV, connect a streaming device like a Roku or Fire Stick, or plug in an HDMI cable from a laptop. Which one works best depends on whether your TV has YouTube built in, what devices you already have, and whether you want to control playback from your phone or a remote.

The easiest route is usually the one that requires the fewest extra purchases. If your TV is less than five years old and made by Samsung, LG, Sony, or most other major brands, it probably has YouTube already installed. If it does not, a $25 to $40 streaming device is cheaper than an HDMI cable setup and gives you more control options.

Key Takeaways

  • Most modern TVs have YouTube built in — check your TV remote for a YouTube button or look in the app menu before buying anything.
  • Chromecast and AirPlay let you send YouTube from your phone to your TV wirelessly, but both require your phone and TV to be on the same WiFi network.
  • Streaming devices like Roku, Fire Stick, and Apple TV have YouTube pre-installed and let you search and play videos using their remote.
  • An HDMI cable from a laptop or computer works on any TV but requires you to sit near the TV or use a long cable to control playback.

Using YouTube that is already on your TV

If your TV was made in the last five years, YouTube is probably already there. Look for a YouTube button on your remote, or press the Home or Menu button and scroll through the apps. If you see YouTube in the list, select it and sign in with your Google account. That is all you need to do.

Older TVs or budget models may not have YouTube built in. If you cannot find it after checking the app menu, move to one of the other methods below. Do not assume it is there just because the TV is a major brand — some models from five or six years ago did not include it.

Casting from your phone using Chromecast or AirPlay

If you have an Android phone, you can cast YouTube to any TV that has a Chromecast device connected or has Chromecast built in. Open the YouTube app, tap the cast icon (it looks like a rectangle with WiFi waves), select your TV from the list, and the video will play on your screen. Your phone acts as the remote — you can pause, skip, and adjust volume from the app.

If you have an iPhone or iPad, use AirPlay instead. Open YouTube in Safari or the YouTube app, tap the AirPlay icon (it looks like a triangle with a rectangle below it), and select your Apple TV or AirPlay-compatible TV. The video will play on your TV while you control it from your device.

Both methods require your phone and TV to be connected to the same WiFi network. If they are on different networks, casting will not work. Also, your TV must either have Chromecast or AirPlay built in, or you need a separate Chromecast or Apple TV device plugged into an HDMI port.

Using a streaming device like Roku or Fire Stick

A streaming device is a small box that plugs into your TV's HDMI port and connects to your WiFi. Roku, Amazon Fire Stick, and Apple TV all have YouTube pre-installed. Plug the device in, connect it to your WiFi, sign into your Google account, and YouTube is ready to use. You control everything with the device's remote.

Streaming devices cost between $25 and $100 depending on the model and features. A basic Roku or Fire Stick is usually under $40 and works well for YouTube. More expensive models offer faster performance or additional features like 4K video support, but for YouTube alone, the basic versions are sufficient.

The advantage of a streaming device is that it stays connected to your TV permanently. You do not need to have your phone nearby, and multiple people can use the same YouTube account or sign in with their own. The remote is usually simpler to use than casting from a phone, especially if you are searching for videos or navigating menus.

Connecting a laptop or computer with an HDMI cable

Any laptop or desktop computer can connect to any TV using an HDMI cable. Plug one end into your computer's HDMI port and the other into your TV's HDMI port. Your computer screen will appear on the TV. Open YouTube in your web browser and play videos as normal.

HDMI cables are inexpensive — usually $5 to $15 — but you need to be close enough to your TV to use the keyboard and trackpad, or you need to buy a wireless keyboard and mouse. This method works if you already have a computer you want to use, but it is less convenient than the other options because you cannot easily move around or put the computer away when you are done.

One advantage is that this method works on any TV, even very old ones. If your TV has an HDMI port, an HDMI cable will work, regardless of when the TV was made or what brand it is.

Troubleshooting common connection problems

If casting is not working, make sure your phone and TV are on the same WiFi network. If they are on different networks — for example, if your phone is on a guest network — casting will fail. Restart both your phone and TV, then try again. If you still cannot see your TV in the cast list, restart your WiFi router.

If your TV does not recognize an HDMI cable, try a different HDMI port on the TV. Some ports may not be active, or the cable itself may be faulty. Also check that your computer is set to output video to an external display — on Windows, press Windows key + P and select "Extend" or "Duplicate". On Mac, go to System Preferences > Displays and check the arrangement settings.

If YouTube is slow or keeps stopping, your WiFi signal may be weak. Move your TV or router closer to each other, or check whether other devices are using a lot of bandwidth. Restarting your router often fixes streaming problems.

Frequently Asked Questions

Do I need a smart TV to watch YouTube on my TV?

No. If your TV is not smart or does not have YouTube built in, you can use a streaming device, cast from your phone, or connect a computer with an HDMI cable. A smart TV makes it easier, but it is not required.

Can I use YouTube on my TV without WiFi?

No. YouTube requires an internet connection, and all the methods described here use WiFi. If you do not have WiFi, you will need to set up a WiFi network or use a mobile hotspot from your phone.

What is the difference between Chromecast and AirPlay?

Chromecast is Google's casting technology for Android phones and works with most TVs and streaming devices. AirPlay is Apple's version and works with iPhones, iPads, and Apple TVs. They do the same thing but are not compatible with each other.

Can multiple people watch YouTube on the same TV at the same time?

Only one video can play at a time on a single TV. However, multiple people can sign into their own YouTube accounts on a streaming device or built-in app, and they can take turns choosing what to watch.

Is it better to cast from my phone or use a streaming device?

Casting is better if you want to control playback from your phone and do not want to buy extra hardware. A streaming device is better if you want a dedicated remote, multiple people will use YouTube, or you want the TV to stay connected without your phone nearby.
