The three ways to connect your phone to your TV
You can connect your phone to your TV using a cable plugged into the TV's HDMI port, by casting wirelessly through an app, or by mirroring your screen without an app. Which one works depends on what TV and phone you own, what's already plugged in, and whether you want to show video, photos, or just mirror everything on your screen.
The fastest route is usually a cable if your TV is nearby and you have one on hand. Wireless casting works from anywhere in your home but requires both devices to be on the same Wi-Fi network. Screen mirroring is built into most phones and TVs made in the last five years, though the setup steps differ by brand.
Key Takeaways
- An HDMI cable plugged directly into your TV's HDMI port is the most reliable method and works with almost any phone using a USB-C or Lightning adapter.
- Wireless casting through apps like Google Home, AirPlay, or Samsung SmartThings requires both devices on the same Wi-Fi network and works from anywhere in your home.
- Screen mirroring built into your phone's settings lets you duplicate your entire screen without downloading an app, though setup steps vary by phone and TV brand.
- Older TVs without HDMI or wireless features can still connect to phones through an adapter that converts the signal to standard video input (RCA or composite).
Using an HDMI cable — the wired connection
An HDMI cable plugged directly into your TV gives you the most stable connection and works with nearly every phone and TV combination. You'll need a USB-C to HDMI adapter (for Android phones) or a Lightning to HDMI adapter (for iPhones), then plug the HDMI cable into the TV's HDMI port. Most TVs have multiple HDMI ports on the back or side — any of them will work.
Plug the adapter into your phone, connect the HDMI cable to the adapter, then plug the other end into the TV. Switch the TV to the correct HDMI input using the remote's input or source button. Your phone's screen should appear on the TV within a few seconds. This method works instantly, doesn't depend on Wi-Fi, and won't drop the connection if someone else joins your network.
The downside is that you're tethered to a cable, and you'll need to buy an adapter if you don't already own one. USB-C to HDMI adapters cost between $15 and $40, and Lightning adapters typically run $30 to $50. Some adapters also charge your phone while connected, which is useful for longer viewing sessions.
Casting wirelessly through Google Home, AirPlay, or Samsung SmartThings
Wireless casting sends video from your phone to the TV without a cable, but it requires both devices to be connected to the same Wi-Fi network. The steps differ depending on your phone brand and what TV you own.
For Android phones: Open Google Home (the app, not the device), tap the device icon in the top right, select your TV from the list, then tap "Cast my screen" or "Cast media." Your phone's screen will appear on the TV. If your TV doesn't show up in the list, make sure both devices are on the same Wi-Fi network and that your TV supports Google Cast (most smart TVs made after 2015 do).
For iPhones: Swipe down from the top right corner to open Control Center, tap "Screen Mirroring," then select your TV from the list. Your iPhone's screen will duplicate on the TV. This works with Apple TV, AirPlay-compatible smart TVs, and some newer Samsung and LG models. If your TV isn't listed, check that both devices are on the same Wi-Fi network and that AirPlay is turned on in your TV's settings.
For Samsung phones and TVs: Open SmartThings, tap the TV, then select "Mirror" or "Screen Sharing." Some Samsung TVs also support Tap View, which lets you tap your phone against the TV to start mirroring instantly.
Wireless casting works from anywhere in your home and doesn't drain your phone's battery as quickly as a cable connection. The trade-off is that the connection can lag slightly during fast-moving content, and it will drop if someone disconnects the TV from Wi-Fi or if your phone moves out of range.
Screen mirroring built into your phone and TV settings
Most phones and TVs made in the last five years have built-in screen mirroring that doesn't require downloading an app. The setup is different for each brand, but the basic idea is the same: you turn on mirroring in your phone's settings, then select your TV from a list.
Android phones: Go to Settings, then Display, then look for "Cast," "Screen Mirroring," or "Wireless Display." Tap it, then select your TV. Some Android phones call this feature "Smart View" or "Screen Share" instead. If you don't see the option, your phone may not support it, or your TV may not be compatible.
iPhones: Swipe down from the top right to open Control Center, tap "Screen Mirroring," then select your TV. This is the same as the AirPlay method described above — Apple calls both features screen mirroring.
For older TVs without built-in wireless: You can still connect your phone using an adapter that converts the signal to RCA (red, white, and yellow cables) or composite video input. These adapters cost $20 to $40 and work with most phones, though the video quality is lower than HDMI or wireless casting.
Troubleshooting when your phone won't connect
If your phone doesn't show up on the TV or the connection keeps dropping, start by checking that both devices are on the same Wi-Fi network. Open your phone's Wi-Fi settings and your TV's network settings and confirm they're connected to the same network name. If they're on different networks, connect your phone to the TV's network.
Restart both devices: turn off the TV and phone completely, wait 10 seconds, then turn them back on. This clears temporary connection problems that prevent pairing. If you're using a cable, unplug it, wait a few seconds, then plug it back in and make sure it's fully inserted into both the phone and the TV.
Check that your TV's input is set correctly. Use the remote's input or source button to cycle through the available inputs until you see your phone's screen. If you're using wireless casting and your TV still doesn't appear in the list, turn off your TV's Wi-Fi, wait 30 seconds, then turn it back on. Some TVs need to reconnect to the network before they show up in casting apps.
If you're using an HDMI adapter, try a different USB-C or Lightning cable — the cable itself may be damaged. If you're casting wirelessly and the connection keeps dropping, move your phone closer to the TV or router. Walls and distance can weaken the Wi-Fi signal and cause the connection to fail.
Comparing the three methods side by side
| Method | Setup Time | Reliability | Range | Cost |
|---|---|---|---|---|
| HDMI Cable | 30 seconds | Excellent — no drops | Limited by cable length | $15–$50 for adapter |
| Wireless Casting | 10–20 seconds | Good — occasional lag | Anywhere on your Wi-Fi network | Free (built-in or free app) |
| Screen Mirroring | 10–20 seconds | Good — occasional lag | Anywhere on your Wi-Fi network | Free (built-in) |
Frequently Asked Questions
Can I connect my phone to a TV that doesn't have Wi-Fi or HDMI?
Yes, using an adapter that converts your phone's signal to RCA or composite video input. These adapters cost $20 to $40 and work with most phones, though video quality is lower than HDMI. You'll plug the adapter into your phone, then connect the colored cables to the TV's video input ports on the back.
Does wireless casting work if my TV isn't a smart TV?
Not directly, but you can use a streaming device like Google Chromecast, Amazon Fire Stick, or Apple TV plugged into your TV's HDMI port. These devices add wireless casting to any TV. Once set up, casting works the same way as it would on a smart TV.
Will connecting my phone to the TV drain the battery faster?
A wired HDMI connection drains the battery slightly faster than normal use, but some adapters include charging ports so you can plug in while connected. Wireless casting drains the battery more noticeably because your phone is actively transmitting video. If you're watching for more than an hour, plug your phone in.
Can I use my phone as a remote while it's connected to the TV?
Yes, with wireless casting and screen mirroring. Your phone continues to work normally while the TV displays your screen. With a wired HDMI connection, your phone still works, but the TV will show whatever's on your phone's screen, so opening other apps will change what appears on the TV.
What if my phone and TV are different brands?
An HDMI cable works with any phone and any TV, regardless of brand. Wireless casting is more limited — Google Cast works with most Android phones and many smart TVs, while AirPlay works with iPhones and Apple-compatible TVs. Check your TV's manual or settings to see which casting methods it supports.
