The three ways to connect your phone to a TV

You can connect your phone to a TV in three ways: with a cable plugged into the TV's HDMI port, by casting wirelessly through an app, or by mirroring your screen without any app at all. Which one works depends on what TV you have, what phone you have, and whether you want to show everything on your screen or just video and photos.

The cable method is the most reliable — it always works if you have the right cable — but it ties you to one spot. Wireless casting and mirroring let you move around, but they only work if your TV has the right technology built in. Most TVs made in the last five years have at least one wireless option.

Key Takeaways

  • An HDMI cable plugged into your TV's HDMI port works with any phone and any TV, but you need the correct adapter for your phone model.
  • Wireless casting through apps like Chromecast, AirPlay, or Roku requires your TV to have that specific technology, but lets you move around freely.
  • Screen mirroring copies everything on your phone to the TV without needing an app, and works on most newer TVs with Android or Apple phones.
  • Check your TV's manual or the back panel to see which ports and wireless options your specific model supports.
  • If wireless doesn't work, a cable is always your backup — it requires no setup and works immediately.

Connecting with an HDMI cable

An HDMI cable is the most straightforward method because it works with almost any phone and TV combination. You need three things: an HDMI cable (about $10 to $20), an adapter that fits your phone's charging port, and an HDMI port on your TV. Look at the back or side of your TV — you will see a port labeled HDMI. Most TVs have at least two.

The adapter depends on your phone. If you have an iPhone, you need a Lightning to HDMI adapter. If you have a Samsung, Google Pixel, or most Android phones, you need a USB-C to HDMI adapter. Plug the adapter into your phone's charging port, plug the HDMI cable into the adapter, then plug the other end of the cable into any HDMI port on your TV. Switch your TV to that HDMI input using your remote — usually a button labeled "Input" or "Source" — and your phone screen appears on the TV immediately.

The downside is that your phone stays tethered to the TV. If the cable is six feet long, you cannot walk more than six feet away. Also, your phone will not charge while it is connected this way unless you use a special powered adapter, which costs more.

Casting through Chromecast, AirPlay, or Roku

Casting sends video and audio from your phone to the TV through your home WiFi network, so you can move around freely. The catch is that your TV must have the right casting technology built in. Google Chromecast, Apple AirPlay, and Roku are the three main systems. Many modern TVs have one or more of these built in, but not all.

To find out what your TV supports, check the manual that came with it or look up your TV model online. You can also look at the TV's settings menu — on most TVs, go to Settings, then look for a section called "AirPlay", "Chromecast", "Roku", or "Wireless Display". If you see one of these options, your TV has that technology.

If your TV has Chromecast, open any app on your phone that supports casting — YouTube, Netflix, Spotify, Google Photos, and many others have a cast button. Tap the cast button, select your TV from the list, and the video or music plays on your TV. If your TV has AirPlay and you have an iPhone, swipe down from the top right corner of your screen to open Control Center, tap "Screen Mirroring", select your TV, and your entire phone screen appears on the TV. If your TV has Roku, use the Roku app on your phone to cast content the same way you would with Chromecast.

Casting only works when your phone and TV are on the same WiFi network. If they are on different networks or your WiFi is weak, casting will not connect or will drop frequently.

Screen mirroring on Android and Apple phones

Screen mirroring copies everything on your phone screen to your TV without needing an app or a cable. It works differently depending on whether you have an Android phone or an iPhone, and it requires your TV to support the wireless standard your phone uses.

On an iPhone, screen mirroring uses AirPlay. Swipe down from the top right corner to open Control Center, tap "Screen Mirroring", and select your TV from the list. Your entire phone screen appears on the TV. This works on most Apple TVs and many newer Samsung, LG, and Sony TVs made in the last three to five years.

On an Android phone, screen mirroring is called "Cast" or "Wireless Display" depending on your phone model. Swipe down twice from the top of your screen to open Quick Settings, look for a button labeled "Cast", "Screen Cast", or "Wireless Display", tap it, and select your TV. If you do not see a cast option in Quick Settings, go to Settings, search for "cast" or "display", and look for a wireless display option there. Android mirroring works on most newer TVs, but support varies by manufacturer.

Screen mirroring is slower than casting — there is usually a one-second delay between what you do on your phone and what appears on the TV. This makes it fine for photos and web browsing, but not ideal for fast-action games or videos where timing matters.

What to do if nothing connects

If wireless casting or mirroring is not working, start by checking that your phone and TV are on the same WiFi network. Open your phone's WiFi settings and your TV's network settings and confirm they both show the same network name. If they are on different networks, connect your phone to the TV's network.

If they are on the same network and still nothing appears, restart both devices. Turn off your TV completely, wait 10 seconds, and turn it back on. Then restart your phone. After both devices restart, try connecting again.

If wireless still does not work, fall back to the HDMI cable method. A cable always works as long as you have the right adapter for your phone and an available HDMI port on your TV. It requires no setup, no WiFi, and no troubleshooting.

Choosing the right method for what you want to do

Use an HDMI cable if you want the most reliable connection and do not mind staying in one spot. This is the best choice for presentations, showing photos to a group, or anything where the connection dropping would be a problem.

Use casting through an app if you want to send just video or music and move around freely. This works great for Netflix, YouTube, Spotify, or any app that has a cast button built in.

Use screen mirroring if you want to show your entire phone screen — web pages, text messages, photos, or anything else — and your TV supports it. This is the most flexible option, but it has a slight delay and works best on newer TVs.

If you are not sure which method will work, start with screen mirroring or casting since they are wireless and require no cables or adapters. If those do not work, buy an HDMI adapter for your phone — they cost $10 to $20 and work with any TV.

Frequently Asked Questions

Do I need a special TV to connect my phone wirelessly?

Most TVs made in the last five years have at least one wireless option built in, but older TVs may not. Check your TV's manual or settings menu to see if it supports AirPlay, Chromecast, or Roku. If it does not, you can buy a separate device like a Chromecast dongle or Roku stick that plugs into an HDMI port and adds wireless casting to any TV.

Can I charge my phone while it is connected to the TV with a cable?

Not with a standard HDMI adapter. You can buy a powered HDMI adapter that has a separate port for charging, but these cost more and are harder to find. Wireless casting and mirroring do not use your charging port, so your phone can charge normally while connected.

Why is my casting connection dropping or lagging?

Casting depends on your WiFi signal. If your phone or TV is far from your router, the signal may be weak. Move closer to the router, or restart both your phone and TV. If your WiFi network is crowded with many devices, the connection may lag. Switching to a wired HDMI connection eliminates this problem.

What if my TV does not have HDMI ports?

Very old TVs may only have composite (red, white, yellow) ports. You can buy a composite to HDMI converter for $15 to $30, but these add extra steps and are not ideal. If your TV is that old, buying a Chromecast or Roku device is usually easier and cheaper than dealing with adapters.

Can I use my phone as a remote control for the TV?

Yes, but only if your TV supports it. Most Samsung, LG, and Sony TVs have a built-in remote app you can download from your phone's app store. Apple TV has a remote app as well. Search your TV brand plus "remote app" in your phone's app store to see if one exists for your model.
