The three ways to get your phone's picture on a TV screen

You can connect your phone to a TV using a cable plugged into both devices, by casting wirelessly through your home network, or by using an adapter that converts your phone's connector to an HDMI port. Which method works depends on what phone and TV you own, what cables you have on hand, and whether you want a permanent connection or something you can disconnect quickly.

The wired methods are the most reliable — the picture won't drop if someone walks between your phone and TV. Wireless casting is more convenient if you move your phone around or want to share the screen without passing a cable. Most people find they use one method regularly and keep the others as backup.

Key Takeaways

  • A wired HDMI connection gives you the most stable picture and charges your phone at the same time, but requires an adapter if your phone doesn't have an HDMI port.
  • Casting wirelessly through apps like Chromecast, AirPlay, or Miracast works on most modern phones and TVs but requires both devices on the same Wi-Fi network.
  • USB-C to HDMI adapters cost $15 to $40 and work with most Android phones; iPhones need a Lightning to HDMI adapter or an Apple TV box.
  • If your TV is older and has no HDMI ports, you can use an adapter that converts to composite cables (the red, white, and yellow connectors), though the picture quality will be lower.

Wired connection with an HDMI adapter

The most straightforward wired method is to plug an adapter into your phone's charging port, then plug an HDMI cable into that adapter and into your TV. This works with nearly all Android phones using a USB-C to HDMI adapter. iPhones require a Lightning to HDMI adapter, which Apple sells but third-party versions are cheaper and work the same way.

When you plug in the adapter, your phone's screen appears on the TV almost when ready. The TV will ask you to select the correct HDMI input — usually labeled HDMI 1, HDMI 2, or HDMI 3 on the remote. Once you select it, everything your phone displays shows on the TV. Many adapters also charge your phone while it's connected, which is useful if you're watching for more than an hour.

The main limitation is that you're tethered to a cable. If you want to move around the room or hand the phone to someone else, you have to unplug and replug. Some adapters are bulky and stick out from the phone awkwardly, though slim versions exist if you search for "low-profile HDMI adapter."

Wireless casting through your home network

Casting means sending your phone's screen to the TV over Wi-Fi without a cable. Android phones use Google Cast (built into most phones made after 2015), iPhones use AirPlay (built into all iPhones), and some TVs support Miracast (a standard that works with both). All three methods require your phone and TV to be connected to the same Wi-Fi network.

To cast from an Android phone, swipe down from the top of the screen twice to open Quick Settings, tap "Cast" or "Screen Cast," and select your TV from the list. The TV's picture appears on your phone's screen within a few seconds. To cast from an iPhone, swipe down from the top-right corner, hold down the screen mirroring icon, and select your TV. On both phones, you can stop casting by tapping the cast icon again and selecting "Disconnect."

Casting is convenient because you can move your phone around the room and the picture stays on the TV. The downside is that if someone else connects to your Wi-Fi and starts a large read, or if your router is far from the TV, the picture can stutter or drop. Casting also drains your phone's battery faster than a wired connection because the Wi-Fi radio stays active.

What to do if your TV is older or doesn't have HDMI

Older TVs have composite ports instead of HDMI — three round connectors, usually colored red, white, and yellow. You can still connect a modern phone to these TVs using a USB-C to composite adapter (for Android) or a Lightning to composite adapter (for iPhone). These adapters are less common than HDMI adapters and cost $20 to $50.

The picture quality on composite is noticeably lower than HDMI — colors are less sharp and the resolution is limited. If your TV has only composite ports and casting doesn't work, a composite adapter is your only wired option. Many people in this situation find that casting works well enough and skip the adapter entirely.

Checking what ports your TV actually has

Before you buy an adapter, look at the back or side of your TV for the ports. HDMI ports are rectangular slots about the size of a USB port. Most TVs made after 2010 have at least one HDMI port. If you see three round connectors (red, white, yellow), you have composite ports. If you see a single round connector labeled "RF In" or "Antenna," your TV is older and may not support any of these methods without a converter box.

If you're not sure what you have, the TV's model number is usually on a sticker on the back. You can search that model number plus "ports" or "connections" online and find a diagram. Many TV manuals are available as PDFs on the manufacturer's website.

Which method to choose for different situations

Use a wired HDMI connection if you're watching for a long time, playing games, or showing photos and videos to a group — the picture won't drop and your phone stays charged. Use casting if you want to move around, show something quickly, or don't want to buy an adapter. Use a composite adapter only if your TV has no HDMI and casting doesn't work.

If you do this regularly, consider buying both an HDMI adapter and using casting as backup. An HDMI adapter costs $15 to $40 and lasts years. Casting is free if your devices support it, which most modern ones do.

Troubleshooting when the connection doesn't work

If you plug in an HDMI adapter and nothing appears on the TV, first check that you selected the right HDMI input on the TV remote. The TV won't show your phone's picture unless you're on the correct input. If the input is correct and still nothing appears, try unplugging the adapter, waiting 10 seconds, and plugging it back in.

If casting isn't working, make sure both your phone and TV are on the same Wi-Fi network. Some networks separate devices into different bands (2.4 GHz and 5 GHz) — if your phone is on one and your TV is on the other, they won't see each other. Check your router's settings or ask your internet provider. If the TV still doesn't appear in the cast list after 30 seconds, restart both devices.

Frequently Asked Questions

Do I need a special TV to connect my phone?

No. Any TV with an HDMI port works with an adapter. If your TV has no HDMI, you can use a composite adapter or casting if your TV supports it. Even very old TVs can work with the right adapter, though picture quality may be lower.

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

Yes, if you use an adapter that supports charging. Most USB-C to HDMI adapters include a charging port, but check the product description before buying. Lightning to HDMI adapters usually don't charge, so you may need a separate charger.

Will casting work if my Wi-Fi is slow?

Casting works on slow Wi-Fi, but the picture may stutter or pause if your connection is very weak. A wired HDMI connection is more reliable if your Wi-Fi is unreliable. If casting keeps dropping, move closer to your router or use an HDMI adapter instead.

What's the difference between casting and screen mirroring?

Screen mirroring and casting mean the same thing — sending your phone's display to the TV over Wi-Fi. Different manufacturers use different names: Google calls it Cast, Apple calls it AirPlay, and some TVs call it Miracast. They all work the same way.

Can I connect two phones to the same TV at the same time?

With a wired connection, only one phone can be plugged in at a time. With casting, most TVs let only one device cast at a time, though some newer models support multiple casters. Check your TV's manual to see if it supports this feature.
