Modern smartphones such as iPhone 10 (also known as the iPhone X) offer powerful multimedia capabilities that make them ideal for enjoying on a larger screen. You often need to share a presentation with colleagues, watch a movie with the family, or simply show off high-resolution photos. Wireless technology allows you to do this without the hassle of wires, using only your home Wi-Fi network and built-in operating system features.
The screencasting process is based on technology AirPlay, which is built into iOS by default. For this scenario to work successfully, it's important that both devices are in the same information space. In this article, we'll detail the steps, potential issues, and alternative connection methods if the standard method is unavailable for some reason.
Before setting up, make sure your router supports latency-free multimedia traffic transmission standards. Connection stability directly impacts picture quality and audio synchronization. If you're using a guest network or limited corporate Wi-Fi, connecting may be impossible.
Technical requirements and equipment preparation
The first step is to check your TV's compatibility. Not all Smart TV models support Apple's native protocol. If you have a modern Samsung, LG, Sony, or Vizio TV released after 2018, AirPlay 2 support is likely already built into the system.
Owners of older models or budget brands may need an external device. This could be Apple TV, an Android TV set-top box, or a dedicated HDMI adapter. Without a receiving device that supports Apple protocols, wireless image transmission is impossible.
A critical requirement is that the devices are on the same subnet. This means that iPhone 10The device and TV must be connected to the same router. If you have a dual-band router, make sure both devices are on the same frequency (e.g., 5 GHz), although modern routers usually route traffic correctly between bands.
⚠️ Note: Some routers have a feature called "Client Isolation" that prevents devices from seeing each other on the network. If the connection fails, check your router's security settings and disable AP isolation.
It's also worth updating your software. On your iPhone, go to Settings → General → Software Update and install the latest available version of iOS. On your TV, navigate to the system updates section in the settings menu and perform a firmware update if available.
Using the built-in AirPlay feature
The easiest and highest quality way to broadcast content is to use the native function AirPlayThis protocol enables high-definition video streaming with minimal latency. To get started, make sure AirPlay is enabled on your TV. In the TV menu, this may be called "Apple AirPlay," "Screen Share," or "MirrorLink."
On your iPhone 10, open the content you want to share. If you're in the YouTube, Netflix, or Apple TV app, look for the rectangle with a triangle at the bottom (or top) of the screen. Tapping it will display a list of available devices.
If you need to broadcast the entire screen, for example, to demonstrate the Safari browser or a game:
- 📱 Swipe down from the top right corner of the screen (or from the bottom up on models with a button) to open Control center.
- 📺 Click on the icon
Screen mirroring(two intersecting rectangles). - 📡 Select the name of your TV from the list that appears.
- 🔑 If a four-digit code appears on the TV screen, enter it on your iPhone to confirm pairing.
Once successfully connected, the image from your smartphone's display will be mirrored on your TV. A blue light will appear in the iPhone's top status bar, indicating active casting. To stop the process, open Control Center again and tap Stop repeating.
☑️ Check before connecting AirPlay
Setting up Smart TVs of various brands
The signal reception setup interface may vary depending on the TV manufacturer. Below is a table with typical paths to the required settings for popular brands. Please note that menu item names may vary slightly depending on the firmware version.
| Brand TV | Path to the menu | The required option |
|---|---|---|
| Samsung | Settings → General → External Device Manager Settings | AirPlay list |
| LG (WebOS) | Settings → Connection → AirPlay | Enable AirPlay |
| Sony (Android TV) | Settings → AirPlay and HomeKit | Require code (optional) |
| Vizio | Menu → System → Smart View | Connections |
In some cases, the TV may ask for permission to connect the first time it's launched. Use the remote control to select "Allow" or "Always Allow." This will eliminate the need to enter the code each time you connect.
If your TV runs Android TV but doesn't have built-in AirPlay, you can try installing third-party apps from the Google Play Store, such as AirScreen or Receiver for AirPlayThey emulate the Apple receiver and allow you to connect your iPhone to your TV via Wi-Fi even without official support.
What to do if the TV doesn't detect the iPhone?
Make sure the "Client Isolation" feature is not enabled on your router. Try temporarily disabling your router's antivirus software, if applicable. Switching your Wi-Fi frequency from 5 GHz to 2.4 GHz or vice versa may also help.
Using translator applications
When standard tools fail or their functionality is limited, specialized apps come to the rescue. They often offer advanced features, such as streaming video formats unsupported by the standard player or file system management.
A popular solution is the app Cast to TV or Web Video CasterThe principle behind their operation is that the app acts as an intermediary. You select a file in the app on your iPhone, and it sends a link or data stream to the receiving app installed on your Smart TV.
The algorithm of actions usually looks like this:
- 📥 Download the same app on your iPhone 10 and your TV (from the App Store and TV app store, respectively).
- 🔗 Launch the app on both devices and wait until they detect each other on the local network.
- 📂 Select a video file or photo from your smartphone's memory.
- ▶️ Click the button Cast or the broadcast icon to start playback.
The advantage of such programs is their support for a wide range of codecs. If your TV's built-in player doesn't recognize the format MKV or AVI, a third-party application will often take over the decoding or stream the stream in a compatible format.
⚠️ Please note: Free versions of streaming apps often contain ads. For a comfortable, uninterrupted viewing experience, you may need to purchase the premium version.
Wired connection via adapters
Wireless data transmission is susceptible to interference. If you want a perfect picture without compression artifacts or lag (critical for gaming), it's best to use a cable. For the iPhone 10, which has a Lightning connector, you'll need a special adapter.
You will need an adapter. Lightning to HDMI (Digital AV Adapter). It is recommended to use an original Apple accessory or one certified under the program. MFi (Made for iPhone), as cheap analogs may not transmit sound or work unstably.
The connection diagram is simple:
- Connect the Lightning adapter to the iPhone 10 charging port.
- Insert the HDMI cable into the adapter and into an available port on your TV.
- Switch the signal source to TV (button
SourceorInput) to the corresponding HDMI port.
The image will appear automatically. Unlike AirPlay, it doesn't require a Wi-Fi network, and the image quality will be the highest supported by the screen (up to 1080p for iPhone 10). You can also connect a charger via the Lightning port to keep the battery charged during extended viewing sessions.
Troubleshooting and error resolution
Despite the simplicity of the technology, users often encounter difficulties. One of the most common issues is that the TV doesn't appear in the list of available devices. In this case, check whether the router's firewall is blocking local traffic.
Another common complaint is audio and video desync. This almost always indicates a congested Wi-Fi channel. If there's a nearby device or neighboring networks are interfering, try moving the router closer to the TV or switching to the 5 GHz frequency, which is less congested but has a shorter range.
If there is no sound at all:
- 🔇 Check if the iPhone itself is in Silent mode.
- 🔊 Make sure that the audio output device is selected in the AirPlay settings (sometimes the audio remains on the phone).
- 🔄 Restart both devices - this clears temporary network conflicts.
In some cases, resetting network settings on your iPhone can help. Go to Settings → General → Reset → Reset network settingsPlease note that you will need to re-enter your Wi-Fi password after this.
Why won't my iPhone 10 connect to my old TV?
Older TVs (made before 2015-2016) often lack built-in AirPlay support. In these cases, wireless connection is only possible via external set-top boxes (Apple TV, Chromecast) or HDMI adapters.
Is it possible to connect an iPhone to a TV without Wi-Fi?
Yes, using a Lightning-to-HDMI cable. Some TV models also support a USB connection, but this only works for viewing photos and videos from memory, not for live screen sharing.
Does the connection affect internet speed?
When streaming via AirPlay, most of the traffic is kept within the local network and doesn't consume internet bandwidth unless you're watching online video. However, the video streaming process itself may temporarily reduce overall Wi-Fi bandwidth for other devices.
