The fastest way to get YouTube from your phone to your TV
The simplest method is casting, which sends video from your phone directly to your TV without a cable. On most Android phones and iPhones, you open YouTube, tap the cast icon (a rectangle with a WiFi symbol in the corner), and select 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 — you can pause, skip, or adjust volume from the phone screen.
If your TV doesn't appear in the cast list, make sure your TV is powered on, connected to the same WiFi as your phone, and that casting is turned on in your TV's settings. Most smart TVs made in the last five years support casting. If you have an older TV without built-in casting, you can add it with a separate device like a Google Chromecast, Amazon Fire Stick, or Roku.
Key Takeaways
- Casting through the YouTube app is the easiest method and works on both Android and iPhone as long as your TV and phone share the same WiFi network.
- Your phone acts as a remote once you cast — the video plays on the TV screen while you control playback from your phone.
- If your TV doesn't have built-in casting, a Chromecast, Fire Stick, or Roku device plugged into an HDMI port adds casting for under $40.
- HDMI cables work on Android phones with USB-C or micro-USB ports, but iPhones require a Lightning to HDMI adapter, which is less convenient than casting.
Casting from Android phones
Open the YouTube app and start playing a video. In the top right corner, tap the cast icon — it looks like a small rectangle with curved WiFi lines. A menu appears showing all available devices on your network. Tap your TV's name. The video transfers to your TV when ready, and your phone screen shows playback controls.
If the cast icon doesn't appear, your phone and TV are not on the same WiFi network. Check your phone's WiFi settings and connect to the same network as your TV. Some phones also require you to enable casting in developer settings, though most modern Android devices have this turned on by default. If you still don't see your TV listed, restart both devices and try again.
Casting from iPhones
The process on iPhone is nearly identical. Open YouTube, start a video, and tap the cast icon in the top right. Select your TV from the list. Your iPhone and TV must be connected to the same WiFi network. Once casting begins, your iPhone screen shows pause, play, and volume controls, but the video itself plays only on the TV.
iPhones sometimes take a few seconds longer to detect available devices than Android phones do. If your TV doesn't appear, make sure AirPlay is enabled in your TV's settings — this is Apple's name for the casting feature. Restart your iPhone and TV if needed. Unlike Android, iPhones do not support HDMI cables directly, so casting is your best option for a wireless connection.
Using an HDMI cable on Android phones
If your phone has a USB-C or micro-USB port, you can connect it directly to your TV with an HDMI cable and an adapter. The adapter converts your phone's charging port to HDMI. Plug the adapter into your phone, connect the HDMI cable to the adapter, and plug the other end into an available HDMI port on your TV. Switch your TV to that HDMI input, and your phone screen appears on the TV.
This method works reliably but has drawbacks. Your phone stays tethered to the TV, and the cable can be awkward if you want to move around. Battery drains faster because the phone is powering the HDMI connection. Casting is usually more convenient, but a wired connection is useful if your WiFi is unreliable or if you want to charge your phone while using it.
Adding casting to older TVs
If your TV doesn't have built-in casting, a streaming device plugged into an HDMI port adds the feature. Google Chromecast, Amazon Fire Stick, and Roku devices all support YouTube casting. Plug the device into an available HDMI port on your TV, connect it to your WiFi, and your phone can cast to it just as it would to a smart TV. These devices cost between $30 and $50 and work with both Android and iPhone.
Choose based on what else you use: if you already have Amazon Prime, a Fire Stick integrates with your account. If you use Google services, Chromecast works seamlessly. Roku is a neutral choice that works with most services. All three let you cast YouTube from your phone, and all require the same WiFi connection as your phone.
Troubleshooting when casting doesn't work
The most common reason casting fails is that your phone and TV are on different WiFi networks. Check your phone's WiFi settings and make sure it's connected to the same network name as your TV. Some homes have two networks (2.4 GHz and 5 GHz) — your TV might be on one and your phone on the other. Switching your phone to match your TV's network usually solves this.
If both devices are on the same network and the cast icon still doesn't appear, restart your phone and TV. Close the YouTube app completely and reopen it. Make sure your TV's casting feature is turned on — this is called AirPlay on Apple TVs, Miracast on some Android TVs, and may be under a different name on older models. Check your TV's settings menu or manual if you're unsure. If nothing works, your TV may not support casting, and a streaming device is your next option.
Comparing your connection options
| Method | Setup Time | Phone Tethered | Works on Both Platforms |

| HDMI cable (Android only) | 1 minute | Yes | No |
| Streaming device | 5–10 minutes (first time) | No | Yes |
Frequently Asked Questions
Do I need to pay for casting?
No. Casting is a free feature built into YouTube and most smart TVs. If your TV doesn't have it, a streaming device costs money, but the casting itself is free once the device is set up.
Can I use YouTube on my phone while something else plays on the TV?
Once you cast, your phone controls the TV playback but can't play a separate video. If you want to browse YouTube on your phone while the TV plays something else, you need a second device or you must stop casting first.
What if my WiFi keeps dropping during casting?
Move your phone and TV closer to your WiFi router, or switch to the 2.4 GHz network if your router has both 2.4 and 5 GHz bands — 2.4 GHz has longer range but slower speed. If the problem persists, an HDMI cable is more stable because it doesn't depend on WiFi.
Will casting work if my TV is older than 5 years?
Possibly, but not always. Older TVs rarely have built-in casting. A streaming device like Chromecast or Fire Stick plugged into an HDMI port will add casting to any TV made in the last 15 years.
Can I cast from YouTube to a computer monitor?
Not directly. Computer monitors don't have casting built in. You would need a streaming device connected to the monitor via HDMI, or you can use an HDMI cable from your phone to the monitor if your phone supports it.
