The three ways to connect your phone to a TV
You can connect your phone to a TV using a cable, a wireless connection, or a built-in casting feature. Which one works depends on what phone and TV you have, and what you want to do — watch video, mirror your screen, or play audio through the TV's speakers.
The fastest route is usually the wireless option your TV already supports. Most modern TVs have Miracast (Android phones), AirPlay (iPhones), or both. If your TV is older or doesn't have wireless built in, a physical cable is the most reliable backup.
Before you start, check what inputs your TV has on the back or side. You'll see HDMI ports (the flat rectangular ones), USB ports, and possibly older connections like composite or component. Your phone's ports matter too — newer iPhones use USB-C, older ones use Lightning, and Android phones vary.
Key Takeaways
- Wireless casting through Miracast (Android) or AirPlay (iPhone) works without cables if your TV supports it, and you can check by looking in your TV's settings menu under "Cast" or "AirPlay".
- A wired HDMI connection using an adapter is the most reliable method and works with almost any TV, though you need the right adapter for your phone's port type.
- Some phones and TVs support USB-C video output directly, which is simpler than HDMI adapters but only works if both devices have USB-C.
- Casting audio only through Bluetooth or AirPlay lets you use your TV's speakers without mirroring your entire screen.
- If wireless doesn't work, check that both devices are on the same Wi-Fi network and that your TV's casting feature is turned on in settings.
Wireless casting with Miracast or AirPlay
Wireless casting is the easiest method if your TV supports it. Miracast is built into most Android phones and many newer TVs. AirPlay is Apple's version and works with iPhones, iPads, and Apple TVs. Both let you mirror your phone's screen or send video and audio to the TV without a cable.
To use Miracast on an Android phone, open Settings, find "Cast" or "Wireless Display," and tap it. Your phone will search for nearby devices. Select your TV from the list. If your TV doesn't appear, make sure both devices are on the same Wi-Fi network and that your TV has casting turned on — this is usually in the TV's settings under "Cast," "Miracast," or "Screen Mirroring."
For iPhones, swipe down from the top-right corner to open Control Center, tap "Screen Mirroring," and select your TV. Your TV must support AirPlay, which most newer models do. If you don't see your TV listed, check that your iPhone and TV are on the same Wi-Fi network and that AirPlay is enabled in your TV's settings.
If casting starts but the picture is choppy or keeps disconnecting, move your phone closer to the TV or router. Wireless casting uses Wi-Fi, so a weak signal will cause problems. Restarting both devices often fixes connection issues.
Connecting with an HDMI cable and adapter
A wired HDMI connection is the most reliable method and works with any TV that has an HDMI port. You'll need an adapter that matches your phone's port type. Most phones use USB-C, but older iPhones use Lightning, and some older Android phones use Micro-USB.
For USB-C phones, buy a USB-C to HDMI adapter (sometimes called a USB-C HDMI converter). Plug the USB-C end into your phone and the HDMI end into your TV. Your phone's screen should appear on the TV within a few seconds. Some adapters also charge your phone while connected, which is useful for longer viewing sessions.
For iPhones, you need a Lightning to HDMI adapter, sold by Apple and third-party makers. Plug it into the Lightning port on the bottom of your phone, then connect an HDMI cable from the adapter to your TV. The process is the same as with USB-C phones.
If nothing appears on the TV, check that you're using an HDMI port that's actually connected (some TVs have multiple HDMI ports, and you may need to switch inputs using your remote). Also verify the adapter is fully seated in your phone's port — a loose connection is the most common reason this fails.
Using USB-C video output directly
Some newer phones and TVs support USB-C Alt Mode, which lets your phone send video directly through its USB-C port without an adapter. This only works if both your phone and TV have USB-C video support, which is still uncommon on TVs.
To check if your phone supports it, look in Settings under "About Phone" or "Developer Options" — you're looking for mention of "USB-C Alt Mode" or "video output." For your TV, check the manual or manufacturer's website to see if any USB-C ports support video input.
If both devices support it, connect a USB-C cable directly from your phone to your TV's USB-C port. Your phone's screen should appear on the TV. This method is simpler than adapters, but since few TVs have USB-C video input yet, it's not a practical option for most people.
Casting audio only to your TV's speakers
You don't always need to mirror your entire screen. If you just want to play music or a podcast through your TV's speakers, you can cast audio only using Bluetooth or AirPlay.
On Android, open the app you're using (Spotify, YouTube Music, or another music service), look for a speaker icon or "Cast" button, and select your TV. The audio will play through the TV while your phone screen stays dark or shows just the app you're using.
On iPhone, open Control Center, tap the audio card at the top, and select your TV under "AirPlay & Bluetooth." Again, only the audio goes to the TV, not your screen. This is useful for saving battery and keeping your phone free while music plays.
Troubleshooting when nothing appears on the TV
If your phone connects but the TV stays blank, the most common cause is that you're using the wrong HDMI input. Use your TV remote to cycle through inputs (usually a button labeled "Input," "Source," or "HDMI") until you see your phone's screen.
For wireless casting, make sure both devices are on the same Wi-Fi network. Check your phone's Wi-Fi settings and your TV's network settings — they should show the same network name. If they're on different networks, casting won't work.
If your TV doesn't show your phone in the cast list, restart both devices. Turn off your TV completely, wait 10 seconds, and turn it back on. Do the same with your phone. Then try casting again. This fixes most connection problems.
For HDMI cables, try a different cable if you have one — some cables are defective or damaged. Also check that the adapter or cable is fully plugged in on both ends. A connection that looks seated but isn't quite all the way in will show a black screen.
When to use each method
| Method | Best for | Requires | Drawback |
|---|---|---|---|
| Wireless casting (Miracast/AirPlay) | Everyday use, moving around the room | TV with casting support, same Wi-Fi network | Can be choppy on weak Wi-Fi |
| HDMI adapter and cable | Reliable connection, older TVs | Right adapter for your phone, HDMI cable | Phone stays tethered to TV |
| USB-C video output | Simplest wired option | Both phone and TV with USB-C video support | Very few TVs have this yet |
| Audio only (Bluetooth/AirPlay) | Music, podcasts, saving battery | TV with Bluetooth or AirPlay | No video on screen |
Frequently Asked Questions
Do I need a special TV to connect my phone wirelessly?
Most TVs made in the last five years have wireless casting built in. Check your TV's settings menu — look for "Cast," "Miracast," "AirPlay," or "Screen Mirroring." If you don't find any of these, your TV is older and you'll need a wired connection or a separate device like a Chromecast or Roku.
Can I charge my phone while it's connected to the TV?
With wireless casting, yes — your phone stays unplugged. With a wired HDMI connection, some adapters have a USB port that lets you plug in a charger at the same time, but not all do. Check the adapter's description before buying if charging while connected matters to you.
Why does my screen keep disconnecting from the TV?
Wireless casting disconnects when the Wi-Fi signal is weak or when your phone goes to sleep. Move closer to your router, turn off Wi-Fi sleep mode in your phone's settings, and keep your phone awake while casting. If it still disconnects, try a wired HDMI connection instead.
What if my TV is really old and doesn't have HDMI?
Older TVs with composite inputs (red, white, and yellow cables) need a different adapter — a USB-C or Lightning to composite converter. These are less common and harder to find than HDMI adapters. A simpler option is to buy an inexpensive streaming device like a Chromecast or Roku, which plugs into HDMI and lets you cast from your phone.
Can I use my phone as a remote while the screen is mirrored?
Not while mirroring — your phone shows exactly what the TV shows, so you can't control anything else. If you need to use your phone while something plays on the TV, cast audio only instead, or use your TV's remote to control playback.
