The simplest way to connect your phone to your TV
The easiest method depends on what TV and phone you own. If your TV has a HDMI port (a rectangular slot about the size of a USB port), you can buy an adapter cable that matches your phone's charging port — USB-C, Lightning, or Micro-USB — and plug one end into your phone and the other into the TV. The TV will display your phone's screen when ready. If your TV doesn't have HDMI or you don't want to use a cable, most modern TVs support wireless casting, which lets you send video and audio from your phone through the air without plugging anything in.
Wireless casting works differently depending on your phone. Android phones use a feature called Cast or Screen Cast (the name varies by manufacturer). iPhones use AirPlay. Both require your phone and TV to be on the same WiFi network. The TV must also support the casting standard — most TVs made in the last five years do, but older models may not.
Key Takeaways
- A wired HDMI adapter is the fastest and most reliable method, requiring only a cable that matches your phone's charging port.
- Wireless casting (Cast for Android, AirPlay for iPhone) works without cables but requires both devices on the same WiFi network.
- Your TV must have either an HDMI port for wired connection or built-in casting support for wireless connection.
- Once connected, your phone's screen appears on the TV, and you can control what displays from your phone.
Connecting with a wired HDMI adapter
This is the most straightforward path if your TV has an HDMI port. First, identify your phone's charging port — it will be USB-C (oval-shaped, reversible), Lightning (eight small pins in a rectangle, Apple phones only), or Micro-USB (smaller rectangular slot, older Android phones). Buy an adapter cable that converts your phone's port to HDMI. These cost between $15 and $30 and are sold at most electronics retailers.
Plug the adapter into your phone's charging port, then plug the HDMI cable end into any HDMI port on the back or side of your TV. Turn on the TV and switch it to the correct HDMI input — use your TV remote to find the input or source button, usually labeled HDMI 1, HDMI 2, or HDMI 3. Your phone's screen should appear on the TV within a few seconds. If it doesn't, unplug the adapter, wait ten seconds, and plug it back in.
The wired method has one major advantage: it works when ready and doesn't depend on WiFi. It also charges your phone while connected. The downside is that you're tethered to the TV by a cable, so you can't move around the room while using it.
Casting wirelessly from an Android phone
Open the settings or notification panel on your Android phone — swipe down from the top of the screen twice to see the full quick-settings menu. Look for a button labeled Cast, Screen Cast, Smart View, or Wireless Display (the exact name depends on your phone's manufacturer). Tap it. Your phone will search for nearby devices that support casting.
Your TV should appear in the list if it's powered on and connected to the same WiFi network as your phone. Tap your TV's name. Your phone will ask for permission to cast — confirm it. Within a few seconds, your phone's screen will appear on the TV. Everything you do on your phone — opening apps, scrolling, typing — will show on the TV in real time.
To stop casting, open the Cast menu again and tap Disconnect or Stop Casting. If your TV doesn't appear in the list, make sure both devices are on the same WiFi network. Restart both your phone and TV, then try again. Some older Android phones or TVs may not support casting at all.
Casting wirelessly from an iPhone
Open Control Center by swiping down from the top-right corner of your iPhone screen (or swiping up from the bottom if you have an older model). Look for a button labeled Screen Mirroring or AirPlay. Tap it. Your iPhone will search for nearby devices that support AirPlay.
Your TV should appear in the list if it's powered on and connected to the same WiFi network as your iPhone. Tap your TV's name. Some TVs will ask you to confirm the connection on the TV itself — if so, follow the on-screen prompt. Your iPhone's screen will then appear on the TV. Everything you do on your iPhone will display on the TV.
To stop mirroring, open Control Center again, tap Screen Mirroring, and select Stop Mirroring. If your TV doesn't appear in the list, confirm both devices are on the same WiFi network. Restart your iPhone and TV, then try again. Not all older TVs support AirPlay — check your TV's manual or settings to see if the feature is available.
What to do if your TV doesn't support casting
If your TV is more than ten years old or doesn't have built-in casting, you have two options. The first is to buy a streaming device like a Roku, Amazon Fire Stick, or Google Chromecast. These are small boxes or sticks that plug into your TV's HDMI port and add casting support. They cost between $30 and $100 depending on the model. Once plugged in and connected to WiFi, they let you cast from your phone just as if the TV had built-in support.
The second option is to use a wired HDMI adapter, which works with any TV that has an HDMI port, regardless of age or casting support. This is often cheaper than a streaming device if you only need to connect occasionally, but it requires a cable and limits your movement.
Troubleshooting common connection problems
If your phone and TV won't connect, the most common cause is that they're not on the same WiFi network. Check your phone's WiFi settings and make sure it's connected to the same network name as your TV. If your TV doesn't show a WiFi network name, check your TV's settings or manual — some TVs require you to connect to WiFi manually before casting will work.
If the connection keeps dropping, move your phone closer to the TV or router. Wireless casting can be interrupted by walls, distance, or interference from other devices. If you're using a wired HDMI adapter and the screen is black or flickering, try a different HDMI port on your TV, or restart both devices. If the picture appears but sound doesn't, check your TV's volume and make sure the correct input is selected.
If you're using an older phone or TV, the casting standard may not be supported at all. In that case, a wired HDMI adapter is your only option. Check your phone's manual or the TV manufacturer's website to confirm what connection methods are supported.
Frequently Asked Questions
Do I need WiFi to connect my phone to my TV?
Only if you're using wireless casting. Wired HDMI adapters work without WiFi — they connect directly through the cable. If you want to cast wirelessly, both your phone and TV must be on the same WiFi network.
Can I charge my phone while it's connected to the TV?
Yes, if you're using a wired HDMI adapter. The adapter plugs into your phone's charging port, so you can plug a power adapter into the other end of the cable to charge while connected. Wireless casting doesn't charge your phone, so you may want to plug it in separately if you plan to cast for a long time.
Will my phone screen go black if I get a notification while casting?
No. Notifications appear on your phone but don't interrupt what's showing on the TV. You can answer calls or texts without disconnecting from the TV.
What if my TV has an HDMI port but casting still doesn't work?
Not all TVs with HDMI ports support wireless casting — that's a separate feature. Check your TV's manual or settings menu to see if casting is built in. If it's not, you can buy a streaming device like a Roku or Chromecast to add casting support, or use a wired HDMI adapter instead.
Can I connect my phone to a TV at someone else's house?
With a wired adapter, yes — it works anywhere. With wireless casting, you need to connect to their WiFi network first. Ask for the network name and password, connect your phone, then cast to their TV. If their TV doesn't support casting, a wired adapter is your only option.
