The fastest way to send YouTube from your phone to your TV
The simplest method is casting—sending video from your phone directly to your TV without plugging anything in. On most phones and TVs made in the last five years, you can cast YouTube by tapping the cast icon (a rectangle with a WiFi symbol in the corner) inside the YouTube app, then selecting your TV from the list. Your phone and TV must be on the same WiFi network. The video plays on your TV while your phone becomes a remote control.
If you don't see a cast icon in YouTube, your TV may not support casting, or casting is turned off in your TV's settings. In that case, you can use an HDMI cable to plug your phone directly into your TV, or use a streaming device like a Roku, Apple TV, or Fire Stick that sits between your phone and TV.
Key Takeaways
- Casting works wirelessly if your phone and TV are on the same WiFi network and your TV supports casting—look for the cast icon in the YouTube app.
- An HDMI cable plugged into your phone's USB-C or Lightning port and your TV's HDMI input is a wired backup that works on almost any TV.
- Streaming devices like Roku, Apple TV, and Fire Stick let you cast from your phone even if your TV is older and doesn't have built-in casting.
- Your phone controls playback when casting, but you can also use your TV remote if you set up the connection in your TV's settings.
Casting YouTube wirelessly from your phone
Open the YouTube app on your phone and start playing a video. Look for the cast icon—it looks like a rectangle with three curved lines in the bottom-right corner of the video player. Tap it. Your phone will search for nearby devices on your WiFi network and show a list of TVs and speakers it finds.
Select your TV's name from the list. YouTube will begin playing on your TV screen within a few seconds. Your phone screen will show a smaller version of the video and playback controls. You can pause, rewind, skip forward, or adjust volume from your phone, and the changes happen on your TV when ready.
If the cast icon doesn't appear, check that your TV supports casting. Most Samsung, LG, Sony, and Vizio TVs made after 2015 have casting built in. If your TV is older, you'll need a streaming device or an HDMI cable instead. Also confirm that both your phone and TV are connected to the same WiFi network—if they're on different networks, casting won't work.
Using an HDMI cable for a wired connection
An HDMI cable is a physical backup that works on almost any TV, even older models without WiFi. You'll need an adapter that matches your phone's charging port. Most Android phones use USB-C, while iPhones use Lightning. Buy a USB-C to HDMI adapter or Lightning to HDMI adapter from any electronics store—they cost $15 to $30.
Plug the adapter into your phone's charging port, then plug an HDMI cable into the adapter. Plug the other end of the HDMI cable into any HDMI port on your TV. Switch your TV to the correct HDMI input using your remote (usually labeled HDMI 1, HDMI 2, etc.). Your phone's screen will appear on your TV. Open YouTube and play a video—it will show on the TV screen.
The downside of an HDMI cable is that your phone stays plugged in and you can't move around. The upside is that it works on any TV with an HDMI port, and there's no WiFi needed. If your phone battery drains quickly, plug it into a power outlet with a long USB cable while the HDMI adapter is connected.
Casting with a streaming device like Roku or Fire Stick
If your TV doesn't have built-in casting, a streaming device plugs into your TV's HDMI port and adds casting capability. Popular options include Roku Streaming Stick, Amazon Fire TV Stick, Google Chromecast, and Apple TV. These devices cost between $25 and $150 depending on the model.
Plug the streaming device into an HDMI port on your TV and follow the setup instructions that come with it. You'll connect it to your WiFi network and sign in with an account (Google, Amazon, or Apple, depending on the device). Once set up, open YouTube on your phone, tap the cast icon, and select your streaming device from the list. YouTube will play on your TV just as it would with built-in casting.
Streaming devices are useful if you plan to cast often, because they're faster and more reliable than HDMI cables, and they work on older TVs. They also let you use other streaming services like Netflix, Disney+, and Hulu directly on your TV without your phone.
Troubleshooting when casting doesn't work
If the cast icon doesn't show up in YouTube, first check that your phone and TV are on the same WiFi network. Open your phone's WiFi settings and confirm the network name. Then open your TV's WiFi settings and confirm it's connected to the same network. If they're on different networks, disconnect one and reconnect it to match the other.
If they're on the same network but the cast icon still doesn't appear, restart both devices. Turn off your phone and TV completely, wait 10 seconds, and turn them back on. Open YouTube again and look for the cast icon. If it still doesn't show, your TV may not support casting—check your TV's manual or settings menu for a "casting" or "screen mirroring" option and turn it on if it's disabled.
If the cast icon appears but your TV doesn't show up in the list, move your phone closer to your TV. WiFi range can be weak in some rooms. If that doesn't work, restart your WiFi router by unplugging it for 10 seconds and plugging it back in. Wait a minute for it to fully restart, then try casting again.
Using your TV remote to control YouTube after casting
Once YouTube is casting to your TV, you can control it with your phone, but you can also set up your TV remote to work. This depends on your TV brand and model. On Samsung TVs, go to Settings > General > External Device Manager and turn on "Anynet+" (HDMI-CEC). On LG TVs, go to Settings > General > HDMI-CEC and turn it on. On other brands, look for "HDMI-CEC" or "CEC" in the settings menu.
Once HDMI-CEC is enabled, your TV remote will control YouTube playback on your TV. You can pause, play, skip, and adjust volume without touching your phone. Your phone can stay in your pocket or on a table. This only works if your TV supports HDMI-CEC and it's turned on—not all TVs have this feature.
Comparing your connection options
Each method has trade-offs depending on your TV age, WiFi setup, and how often you plan to cast. The table below shows the main differences so you can pick the right one for your situation.
| Method | Cost | Setup Time | Works on Old TVs | Requires WiFi |
|---|---|---|---|---|
| Casting (built-in) | Free | 30 seconds | No | Yes |
| HDMI cable | $15–$30 | 1 minute | Yes | No |
| Streaming device | $25–$150 | 10–15 minutes | Yes | Yes |
Casting is the fastest and cheapest option if your TV supports it. An HDMI cable is the most reliable backup for older TVs or when WiFi isn't available. A streaming device is worth the cost if you cast regularly or want to use other streaming services on your TV.
Frequently Asked Questions
Can I cast YouTube if my TV is really old?
No, older TVs without WiFi or HDMI ports won't support casting. Use an HDMI cable with an adapter if your phone has USB-C or Lightning, or buy a streaming device like a Roku or Fire Stick that plugs into your TV's HDMI port.
Do I need WiFi to use an HDMI cable?
No. An HDMI cable is a wired connection that doesn't use WiFi at all. Your phone connects directly to your TV through the cable, so you only need WiFi if you want to stream YouTube content itself—which you do, but that's a separate connection from the HDMI link.
What if my phone doesn't have an HDMI port?
No modern phone has an HDMI port. You need an adapter that converts your phone's charging port (USB-C or Lightning) to HDMI. These adapters are inexpensive and widely available at electronics stores.
Can I use casting and still control YouTube from my TV remote?
Yes, if your TV supports HDMI-CEC (a feature on most newer TVs). Turn on HDMI-CEC in your TV's settings, and your remote will control YouTube playback. Your phone can stay in your pocket.
Why does casting keep disconnecting?
Casting disconnects when your phone and TV lose WiFi connection or move too far apart. Move closer to your TV and router, restart both devices, and check that they're on the same WiFi network. If it keeps happening, restart your WiFi router.
