The three ways to connect your phone to your TV

You can connect your phone to your TV through a cable plugged into the TV's HDMI port, through a wireless connection using a device like a Chromecast or Roku, or through your TV's built-in wireless features if it has them. The cable method works when ready but requires you to stay near the TV. Wireless methods let you control playback from anywhere in the room and work with most phones, but they take a few minutes to set up the first time.

Which method works for you depends on what TV you have, what phone you have, and whether you want to move around while you're watching. If your TV is smart (meaning it connects to the internet), you likely have at least one wireless option already built in. If your TV is older or basic, a cable or a separate wireless device is your only choice.

Key Takeaways

  • An HDMI cable plugged into your TV's HDMI port is the fastest way to connect any phone, but you need an adapter that matches your phone's charging port.
  • Wireless casting through Chromecast, Roku, or your TV's native app works without cables and lets you control playback from your phone, but both devices must be on the same WiFi network.
  • Smart TVs often have AirPlay (Apple), Miracast (Android), or their own casting app built in, so check your TV's manual or settings before buying extra hardware.
  • The cable method shows everything on your phone's screen, while casting lets you choose what to send to the TV and keep using your phone for other things.

Connecting with an HDMI cable and adapter

An HDMI cable plugged into your TV's HDMI port will display your phone's screen on the TV when ready. You need an adapter that connects your phone's charging port to an HDMI cable. For iPhones, you need a Lightning to HDMI adapter. For Android phones, you need a USB-C to HDMI adapter (or Micro-USB to HDMI if your phone is older). These adapters cost between $15 and $40 and are sold at most electronics stores.

Plug the adapter into your phone's charging port, plug the HDMI cable into the adapter, and plug the other end of the cable into any HDMI port on your TV. Switch your TV to that HDMI input using your remote. Your phone's screen will appear on the TV within a few seconds. Everything you do on your phone — opening apps, scrolling, typing — shows on the TV in real time. When you're done, unplug the cable and your phone returns to normal.

The cable method works with any phone and any TV that has an HDMI port. It does not require WiFi or any setup. The downside is that your phone is tethered to the TV, and the screen stays on the whole time, which drains the battery faster. If you want to use your phone for something else while the TV plays, this method will not work.

Wireless casting with Chromecast or Roku

If you own a Chromecast device (a small box that plugs into your TV's HDMI port) or a Roku device, you can cast video, photos, and audio from your phone to your TV without any cables. Both devices connect to your WiFi network and sit between your phone and TV. To cast, you open an app on your phone — like YouTube, Netflix, or Google Photos — tap the cast icon (usually a rectangle with a WiFi symbol), and select your Chromecast or Roku from the list.

The video then plays on your TV while your phone acts as a remote control. You can lock your phone, open other apps, or set it down, and the TV keeps playing. This is the most flexible method if you want to move around or use your phone for other things while watching.

Chromecast and Roku devices cost between $30 and $100 depending on the model. Both work with iPhones and Android phones. The first time you set one up, you plug it into your TV's HDMI port, connect it to your WiFi network using your phone, and name it. After that, casting takes just a few taps. Not every app supports casting — check the app's menu to see if a cast icon appears.

Using your TV's built-in wireless features

Most smart TVs made in the last five years have wireless casting built in, so you may not need to buy anything extra. iPhones can use AirPlay on Samsung, LG, Sony, and other brands. Android phones can use Miracast on most TVs. Some TVs also have their own casting app — Samsung has SmartThings, LG has LG ThinQ, and others have similar apps.

To use AirPlay on an iPhone, open Control Center (swipe down from the top right on newer iPhones, or up from the bottom on older ones), tap Screen Mirroring, and select your TV from the list. Your iPhone's screen appears on the TV. To use Miracast on an Android phone, go to Settings, find Display or Screen Mirroring, and select your TV. The process varies slightly by phone model and TV brand, so check your TV's manual if you get stuck.

Built-in wireless features work only if your phone and TV are on the same WiFi network. The first time you connect, your TV may ask you to confirm the connection. After that, it remembers your phone and connects faster. These methods are free and require no extra hardware, but they only work if your TV supports them — older TVs or budget models may not have them.

What to do if your phone and TV are on different WiFi networks

Wireless casting requires both devices to be on the same WiFi network. If your phone is on your home WiFi and your TV is on a guest network (or a different network entirely), casting will not work. The simplest fix is to connect your phone to the same network as your TV. Go to your phone's WiFi settings, find the network your TV is on, and connect to it.

If you cannot connect both devices to the same network — for example, if your TV is at a friend's house — use an HDMI cable instead. A cable does not need WiFi and works anywhere. If you are at a location with multiple networks and you are not sure which one the TV is on, ask the person who set up the TV or check the TV's network settings (usually in the Settings menu under Network or WiFi).

Troubleshooting common connection problems

If your phone does not appear in the cast list, restart both your phone and TV. Turn off your phone's WiFi, wait five seconds, and turn it back on. Make sure your TV is actually on and connected to WiFi — check the TV's settings menu to confirm. If you are using an HDMI cable and nothing appears on the TV, try a different HDMI port on the TV, as one port may be broken.

If the connection keeps dropping, move your phone and TV closer together. WiFi signals weaken with distance and through walls. If you are far from your router, the connection may be unstable. Restarting your router (unplugging it for 30 seconds and plugging it back in) often fixes wireless connection problems. If you are still stuck, check whether your TV's manual mentions casting, as some older smart TVs require a software update to support it.

If you are using an app that does not have a cast icon, that app does not support casting to your TV. You can still use an HDMI cable to show the app's screen, but you cannot cast it wirelessly. Check the app's settings or help section to confirm whether casting is supported.

Choosing the right method for your situation

Use an HDMI cable if you want the fastest setup with no WiFi needed, or if your TV is old and does not have wireless features. Use your TV's built-in wireless features if your TV supports them and you want to avoid buying extra hardware. Use Chromecast or Roku if your TV does not have built-in casting, or if you want the most reliable wireless connection and the ability to use your phone while the TV plays.

If you are not sure what your TV supports, check the manual or look up your TV's model number online. Most TV manufacturers list casting features on their website. If you plan to cast often, spending $30 to $50 on a Chromecast or Roku is worth it for the convenience. If you cast rarely, an HDMI cable is cheaper and works with any phone and TV.

Frequently Asked Questions

Do I need WiFi to connect my phone to my TV with a cable?

No. An HDMI cable connection does not use WiFi at all. It works anywhere, even without internet. Wireless casting methods like Chromecast, Roku, and built-in TV features all require WiFi.

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

Not with a standard HDMI adapter. The adapter takes up your phone's charging port. Some high-end adapters have a pass-through charging port, but they cost more and are harder to find. If you need to charge while casting, use a wireless method instead.

Will casting drain my phone's battery faster?

Yes, but not as much as keeping the screen on with an HDMI cable. Wireless casting uses WiFi and keeps your phone's processor active, so the battery drains faster than normal. An HDMI cable keeps your phone's screen on the whole time, which drains the battery much more quickly.

What if my TV does not have an HDMI port?

Very old TVs may have only composite (red, white, yellow) cables or VGA ports. You can buy adapters that convert HDMI to these older formats, but they are uncommon and may not work reliably. If your TV is that old, a wireless device like Chromecast or Roku is not an option either. Consider upgrading to a newer TV if you want to use modern casting features.

Can I cast from my phone to multiple TVs at the same time?

No. You can only cast to one TV at a time with most apps and devices. If you want to play the same content on multiple TVs, you would need to cast to each one separately, one after the other.
