The fastest way depends on what TV and phone you own

Most phones connect wirelessly to TVs through one of three methods: AirPlay (Apple devices), Miracast (Android phones and Windows devices), or Chromecast (Google's system, which works with most Android phones and iPhones). Your TV needs to support the same standard your phone uses, or you need a separate device like a Chromecast dongle or Fire TV stick plugged into an HDMI port.

Before you start, make sure your phone and TV are on the same Wi-Fi network. This is the single most common reason the connection fails. Check your phone's Wi-Fi settings and your TV's network settings to confirm they are both connected to the same network name.

If your TV is older and does not have built-in wireless capability, you can add it with a streaming device — a small box or stick that plugs into your TV's HDMI port. Chromecast, Fire TV, and Roku all work this way and cost between $30 and $50.

Key Takeaways

  • Your phone and TV must be on the same Wi-Fi network before any wireless connection will work.
  • Apple devices use AirPlay, most Android phones use Miracast or Chromecast, and your TV must support the same standard.
  • If your TV does not have wireless built in, a Chromecast, Fire TV, or Roku device plugged into an HDMI port adds the feature for $30 to $50.
  • The connection process takes 30 seconds to two minutes once both devices are on the same network.

Connecting an iPhone or iPad to your TV with AirPlay

Open the Control Center on your iPhone or iPad by swiping down from the top-right corner (or up from the bottom on older models). Look for the Screen Mirroring button — it looks like a rectangle with a triangle at the bottom. Tap it and wait two seconds for your TV to appear in the list.

Select your TV's name from the list. Your phone will ask for a four-digit code that appears on your TV screen — type it into your phone. Once the code is entered, your phone's screen will appear on the TV within a few seconds.

If your TV does not appear in the list, go back and check that both devices are on the same Wi-Fi network. Restart your TV's Wi-Fi connection by going to Settings > Network and selecting your network again. Then try Screen Mirroring once more.

Connecting an Android phone to your TV with Miracast

Open your phone's Settings and look for Display or Connected Devices. The exact name varies by phone brand — Samsung calls it "Smart View," Motorola calls it "Cast Screen," and others may label it differently. Tap that option.

Your phone will scan for available devices. Select your TV's name from the list. Some TVs require you to confirm the connection on the remote control — if you see a prompt on your TV screen, press OK or Yes. Your phone's screen should appear on the TV within 10 to 30 seconds.

If your TV does not appear, check that both devices are on the same Wi-Fi network. Some older Android phones require you to enable Miracast in Developer Options first — if you cannot find the casting option in Settings, search online for "[your phone model] miracast" to find the exact steps for your device.

Using Chromecast or a streaming device

Chromecast, Fire TV, and Roku devices work differently than AirPlay or Miracast. Instead of mirroring your entire phone screen, you open an app on your phone and tell it to send video to the device. This uses less battery and works more reliably over weaker Wi-Fi connections.

First, plug the device into your TV's HDMI port and power it on. Follow the on-screen setup to connect it to your Wi-Fi network. Once it is set up, open an app like YouTube, Netflix, or Spotify on your phone. Look for a Cast button — usually a rectangle with Wi-Fi waves in the corner — and tap it. Select your device from the list, and the video will start playing on your TV.

If you want to mirror your entire phone screen instead of casting from an app, Chromecast and Fire TV both support that too. On Android, open Settings > Display > Cast Screen and select your device. On iPhone with Chromecast, open Control Center, tap Screen Mirroring, and select your Chromecast.

Fixing connection problems

The most common issue is that your phone and TV are not on the same Wi-Fi network. Check your phone's Wi-Fi settings and make sure the network name matches what you see in your TV's network settings. If you have a 5GHz and 2.4GHz network with the same name, try connecting both devices to the 2.4GHz version — some older TVs do not support 5GHz.

If the connection keeps dropping, move your phone and TV closer together. Walls, microwaves, and cordless phones can interfere with Wi-Fi. Restart both devices by turning them off for 10 seconds, then turning them back on. This clears temporary glitches that often cause connection failures.

If you see the TV in the list but cannot connect, restart your TV's Wi-Fi by going to its network settings and disconnecting from Wi-Fi, then reconnecting. Wait 30 seconds before trying to connect your phone again. If the problem persists, restart your Wi-Fi router by unplugging it for 10 seconds.

When wireless connection is not working, use a cable instead

If wireless keeps failing, you can connect with a physical cable. For iPhones, you need an HDMI adapter (officially called a Lightning to HDMI adapter) that plugs into the charging port. For Android phones, you need a USB-C to HDMI adapter or Micro-USB to HDMI adapter depending on your phone's charging port. Both types cost $15 to $30.

Plug the adapter into your phone, connect an HDMI cable to the adapter, and plug the other end into your TV. Switch your TV to the HDMI input where you plugged in the cable. Your phone's screen will appear on the TV immediately — no Wi-Fi required.

Frequently Asked Questions

Do I need a special TV to connect wirelessly?

TVs made in the last five years usually have wireless built in. Older TVs do not, but you can add wireless capability with a Chromecast, Fire TV, or Roku device for $30 to $50. These plug into your TV's HDMI port and do not require any installation.

Can I connect my phone to someone else's TV?

Yes, as long as you can connect to their Wi-Fi network. Ask for the network name and password, connect your phone to it, then use AirPlay, Miracast, or Chromecast as normal. When you leave, disconnect from their Wi-Fi.

Will connecting my phone to the TV drain the battery?

Screen mirroring uses more battery than normal, but casting from an app (like Netflix or YouTube) uses much less. If battery is a concern, use casting instead of mirroring, or plug your phone into a charger while connected.

What if my phone and TV are on different Wi-Fi networks?

They must be on the same network to connect wirelessly. Connect your phone to the same network as your TV, or ask your router administrator to add your phone to the TV's network if they are separate.

Can I use wireless connection while using other apps on my phone?

Yes with casting apps like YouTube or Netflix — you can use other apps while video plays on the TV. With full screen mirroring, your phone's screen is locked to the TV, so you cannot use other apps at the same time.
