Modern smartphones have long since become powerful multimedia centers, but even a 4.7-inch diagonal doesn't always allow you to fully enjoy high-quality content. iPhone 7Despite its age, the TV remains a popular device capable of playing high-definition video. However, for comfortable movie viewing, especially with friends or family, the image needs to be projected onto a large TV screen.
The most convenient and modern way to solve this problem is to use a wireless connection. WiFiThis eliminates the need for tangled wires and allows you to control playback from the palm of your hand, from anywhere in the room. In this article, we'll cover all available syncing methods in detail, from built-in Apple features to third-party apps.
Before you begin setup, it's important to make sure your equipment is ready to go. Both devices – the smartphone and the TV – must be connected to the same WiFi network.If your router is distributing a guest network or is using client isolation, you won't be able to establish a connection. Make sure your router's wireless module is working properly, as video streaming requires high bandwidth.
Using built-in AirPlay to stream
The most native and optimized way to transmit images is the technology AirPlay, developed by Apple. It allows you to mirror your screen or a specific video without lag or loss of quality if your TV supports this protocol. iPhone 7 owners will appreciate its ease of use: just a few taps and the image appears on the big screen.
First, check if your TV has built-in AirPlay 2 support. This feature is available on many modern Samsung, LG, Sony, and Vizio models, as well as Apple TV devices. If it does, you don't need to install any software. Simply unlock your smartphone, open Control center (swipe up from the bottom) and select the "Screen Mirroring" icon.
Select your TV from the list of available devices. If prompted, enter the code that appears on the TV screen. After this, the iPhone 7's image will be mirrored on the TV. You can play any movie from your gallery or streaming service, and it will fill the entire screen.
However, it's important to keep in mind that wireless Full HD video transmission puts a strain on the network. If your router is old or the signal is weak, you may experience choppy images. In this case, try moving closer to the access point or reducing the strain on the network by turning off other devices.
Connecting via apps from TV manufacturers
If your TV doesn't support AirPlay directly, manufacturers often release their own apps for smartphone integration. Ecosystem iOS allows third-party developers to create convenient content management tools. This is a great option for the iPhone 7, as it allows you to fully utilize the Smart TV's potential.
- 📺 Samsung Smart View — the official app for Samsung TVs, allowing you to stream photos, videos, and music, as well as use your phone as a remote control.
- 🎨 LG TV Plus — a universal solution for LG equipment, providing a stable connection and playback control.
- 🌐 Sony Video & TV SideView — an application for Sony devices that helps you find content and display it on your TV screen.
The connection process in such cases is standard. Download the app from the App Store and ensure your phone and TV are on the same WiFi network. Launch the app on your iPhone 7; it will automatically search for compatible devices. Once the TV is detected, follow the on-screen instructions to pair it.
It's important to note that some apps may have limitations on the file formats they can play. For example, the built-in player may not support certain audio codecs or subtitles. In this case, it's better to use third-party video players with DLNA support.
What should I do if the app doesn't detect the TV?
Make sure DLNA or Screen Mirroring is enabled on your TV. You may need to manually allow the connection in the window that appears on the TV screen.
Streaming via Chromecast and Google Home
Owners of Android TVs or devices with a built-in module Chromecast can use the Google ecosystem for streaming. Although the iPhone 7 is an Apple device, Google provides excellent support for its services on iOS through the Google Home app.
To get started, download the Google Home app from the App Store. After installation and signing in to your Google account, the app will scan your network and find available Chromecast devices. Select your TV from the list and click "Cast Screen."
This method is especially convenient if you're watching videos in the Chrome browser on your computer or using Google services like YouTube or Google Photos. The streaming quality is usually high, but may depend on the power of your router. It's also worth keeping in mind that when streaming the entire iPhone 7 screen, the image will have black bars on the sides due to the aspect ratio difference.
Using third-party repeater apps
When built-in methods fail, or your TV is a "basic" Smart TV with limited functionality, universal repeater apps come to the rescue. They create a software bridge between the iPhone 7 and the TV, emulating standard data transfer protocols.
One of the most popular solutions is the application Replica or TV CastThese programs use AirPlay technology, but broadcast the signal in a format compatible with DLNA receivers. This allows you to display the image on virtually any TV connected to the same WiFi network.
Free versions of such apps often contain ads, and image quality may be limited. However, for a one-time movie viewing, this is a perfectly acceptable solution. Paid versions usually remove ads and offer smooth audio, which is crucial for movies.
⚠️ Attention: Free versions of repeater apps can put a significant strain on the iPhone 7 processor, causing the device to overheat. Monitor your smartphone's temperature during extended use.
When choosing an app, pay attention to user reviews specific to your TV model. Compatibility may vary depending on the TV firmware version and operating system.
☑️ Check before installing the app

Network Solution and Optimization
Even with proper setup, connection issues may still occur. These are most often related to an unstable WiFi signal or router settings.

For video streaming, it's best to use the 2.4 GHz band. 5 GHz, as it is less congested and provides higher speed.
If the video is constantly buffering or choppy, try rebooting your router. Also, check if there are any speed limits (QoS) for your device. Changing the WiFi channel in your router settings can sometimes help if neighboring networks are interfering.
⚠️ Attention: TV and app interfaces are frequently updated. The layout of menu items may differ from what's described, so please refer to the function names for their meaning.
