Modern smartphones have high-resolution screens, but viewing a family photo album or sharing a presentation with colleagues often requires a larger screen. Sharing images from an iPhone to a TV via Wi-Fi is a standard feature implemented in the Apple ecosystem through technology. AirPlayThis protocol allows you to transmit content without delays and loss of quality using your home's wireless network.
However, if your TV doesn't natively support Apple products, the process can be confusing. Owners of older Smart TV models or Android TV devices often find that the cast button simply doesn't appear. In this case, DLNA servers and third-party repeater applications that emulate a signal receiver.
In this article, we will look at all possible connection scenarios: from the “native” AirPlay 2 to using third-party software like Belkin or Web Video CastYou'll learn how to configure your network to minimize latency and ensure clear images.
Network requirements and device compatibility
The foundation of successful streaming is a properly organized local network. For AirPlay or DLNA to work, it's critical that both devices—the smartphone and the TV—are on the same network. subnetsThis means that they must be connected to the same router, and not to different guest networks or frequency bands if the router separates them into different VLANs.
Wireless connection speed also plays a key role. To transmit video at a resolution 1080p or 4K A stable channel is required. If your router is dual-band, make sure both devices are connected to the same band. 5 GHz. Frequency 2.4 GHz It is often overloaded with neighboring networks and household appliances, which causes image jerkiness.
As for compatibility, TVs with support AirPlay 2 (Samsung, LG, Sony, Vizio) work with iPhones out of the box. Owners of older models will have to rely on built-in TV apps, such as Smart View or Screen Share, which often use the Miracast protocol, which is incompatible with iOS without intermediaries.
⚠️ Note: Some corporate and hotel networks use client isolation. In these networks, devices see the router but not each other, making broadcasting impossible. In this case, the only solution is to create a personal access point.
Stream via built-in AirPlay
The highest-quality way to stream content is using Apple's native protocol. It supports not only screen mirroring but also multichannel audio. First, make sure AirPlay is enabled on your TV. It's usually found in the menu. Settings → General → AirPlay.
On your iPhone, open Control Center. On models with Face ID, swipe down from the upper-right corner; on models with a Home button, swipe up from the bottom edge. Find the icon Screen Mirroring (two intersecting rectangles). Click on it and select your TV from the list.
☑️ Check before connecting AirPlay
When you first connect, a four-digit code may appear on your TV screen. Enter it on your smartphone screen to confirm. After this, the iPhone's image will be fully mirrored on the big screen. To stop casting, open Control Center again and tap Stop repeating.
Why can't AirPlay see my TV?
Often, the problem lies in the router's power saving settings or whether "Guest Mode" is enabled for Wi-Fi. Also, make sure MAC address filtering isn't enabled on the router, as this can block Bonjour discovery packets.
Using third-party repeater applications
If your TV doesn't support AirPlay, special apps installed on your Smart TV can help. They create a virtual receiver that tricks your iPhone into thinking a compatible Apple TV is nearby.
Popular solutions are applications AirScreen (for Android TV), Receiver for AirPlay Or proprietary utilities from TV manufacturers. After installing such an app on your TV, launch it. It will display the device name and possibly a QR code for quick setup.
The next step is the same: open Control Center on your iPhone, select "Screen Mirroring," and find the name specified in the app on your TV. Picture quality in this case depends on the power of the TV's processor, as it decodes the video stream in real time.
| Application | TV platform | 4K support | Advertising |
|---|---|---|---|
| AirScreen | Android TV | Yes | There is (in) |
| Belkin Connect | Different | Yes | No |
| TV Cast | Tizen/WebOS | Depends | Eat |
| Web Video Cast | All | Yes | Eat |
Transferring video from browsers and players
Often, a user needs to display not the entire smartphone screen, but a specific video from a website. Many browsers on iOS, for example, Safari or Chrome, have a built-in Cast function. Open the video file, click the cast icon (the rectangle with waves), and select a device.
For more complex cases, when a site blocks a live broadcast, aggregator applications are used, such as Web Video CastYou copy the video file link into the app, which analyzes the stream and sends a pre-configured playback command to the TV. In this mode, the iPhone acts only as a remote control, and buffering occurs on the TV or directly from the internet.
This method is especially useful for viewing content from websites that don't have an official Smart TV app. However, it's important to note that DRM (copy protection) on some streaming services may block image transmission, leaving only audio or a black screen.
Problems with latency and image quality
Lag between the action on your phone's screen and what it displays on your TV is the main enemy of wireless streaming. While this can be devastating for gaming, it's not critical for watching videos or photos. The main cause of lag is a congested Wi-Fi channel or a slow TV processor.
To minimize latency, close all background apps on your iPhone that may be consuming data. Also, try restarting your router. If you're using a third-party app, try lowering the streaming video resolution in the repeater app's settings.
⚠️ Note: Smart TV interfaces and menu names may vary depending on the firmware version and manufacturer. If you don't find the option you need, check the official documentation for your TV model, as manufacturers often change the software logic.
Alternative methods: DLNA and clouds
If wireless mirroring is not working reliably, you can use the protocol DLNAIt's designed for transferring media files, not desktop images. To do this, you need to install a server app on your iPhone (for example, 8player or VLC), and launch the built-in media player on the TV.
In the phone app, select a folder with photos or videos and select "Stream." The TV will see your iPhone as a network storage device. This method is ideal for browsing family photo archives, as it allows you to scroll through the gallery using the TV remote.
Another option is to use cloud services. Upload photos to iCloud Photos or Google Photos, install the corresponding app on your Smart TV, and sign in to your account. This completely eliminates the load on your Wi-Fi network while watching, as the TV will automatically download the content from the internet.
Is it possible to broadcast the screen via Bluetooth?
Technically, Bluetooth doesn't have sufficient bandwidth to transmit video. It's only used for the initial handshake when setting up AirPlay, transmitting Wi-Fi network data but not the video stream.
Frequently Asked Questions (FAQ)
Why doesn't my TV appear in the AirPlay list?
Most likely, the devices are on different networks (for example, one on a guest network and the other on the main network) or client isolation is enabled on the router. Also, check whether the router's firewall is blocking the Bonjour protocol (port 5353).
Is it possible to transmit sound separately, without image?
Yes, if you're streaming videos from apps like YouTube or Netflix, the audio will automatically play through your TV. If you only want to stream music, open Control Center, tap the AirPlay Audio icon, and select your TV or speakers.
Does broadcasting affect internet speed?
When mirroring, traffic flows within the local network and doesn't consume internet bandwidth. However, when using DLNA or cloud streaming, internet bandwidth is heavily consumed, which can slow down other devices.
Does my old TV support AirPlay?
Natively—most likely not, unless it's a 2018-2019 or newer model from Samsung, LG, Sony, or Vizio. Older models will require installing a third-party receiver app from the TV's app store.
