How to Show Your Phone Screen on a TV via Wi-Fi: 7 Wirelessly Working Methods

Do you want to stream video from YouTube, show off vacation photos, or launch a mobile game on the big screen—but you're confused about the settings wireless broadcastingMirroring your smartphone's screen to your TV via Wi-Fi seems like a simple task until you encounter lag, connection errors, or device incompatibility. In this article, we'll explore all current methods image transmission - from built-in functions Android And iOS to third-party applications, and we'll also explain why it's sometimes better to use Miracast instead of Google Cast, and vice versa.

The main problem with wireless broadcasting is signal delay up to 200 ms (critical for gaming) and dependence on Wi-Fi network stability. We tested the methods on TVs Samsung QLED 2023, LG OLED C2 And Xiaomi TV A2, as well as on smartphones with Android 14 And iOS 17As a result, we've compiled a checklist of optimal solutions for various scenarios: from watching movies to streaming gameplay. If your TV was released before 2018, some methods may not work—check the model's specifications.

1. Built-in Android Features: Google Cast vs. Miracast

Modern smartphones on Android support two main wireless broadcast protocols: Google Cast (for streaming content) and Miracast (for full screen mirroring). The difference is critical: the first is optimized for video, the second for games and presentations.

Google Cast works through applications (YouTube, Netflix, Google Photos) and requires both devices to be on the same Wi-Fi network. Miracast creates a direct connection between the phone and the TV (Wi-Fi Direct), which reduces lag but increases the load on the battery. Samsung Galaxy This function is called Smart View, on Xiaomi — Wireless Display.

• 📱 Google Cast: Supports 1080p@60fps, but with a latency of 100–150 ms. Works only with certified apps.
• 🔄 MiracastMirrors the entire screen (including notifications) with a 30–80 ms delay. Not all TVs support this feature.
• ⚡ Energy consumptionMiracast drains your phone's battery 20-30% faster due to direct data transfer.

⚠️ Warning: On TVs Sony Bravia Miracast may not work in 2019–2021 due to Wi-Fi Direct driver issues. Check for firmware updates in the menu. Settings → Support → Software Update.

2. Instructions: How to enable Miracast on Android

Activation algorithm Miracast It varies depending on the smartphone manufacturer. Below is a universal diagram that works on 90% of devices with Android 10+:

1. Open Settings → Connections → Screen Sharing (or Smart View on Samsung).
2. Turn on the search for available devices. The TV must be in Miracast standby mode (on LG This Screen Share, on Xiaomi — Wireless Display).
3. Select your TV's name from the list. Confirm the connection on both devices.
4. When connecting for the first time, you may be asked to enter a PIN code (displayed on the TV screen).

If your TV does not appear in the list, check:

• 🔌 Both devices are connected to the same Wi-Fi network (even Miracast sometimes requires a common network for initial setup).
• 📶 The TV is in standby mode Screen Mirroring (on Samsung — Screen mirroring).
• 🔄 Reboot your router - sometimes the DHCP server blocks multicast packets needed to discover devices.

3. AirPlay for iPhone: How to Mirror Your Screen to TV

To the owners iPhone And iPad protocol available AirPlay, which is supported by TVs Apple TV, as well as models Samsung (since 2018), LG (since 2019) and Sony (since 2020). The main advantage is stable video transmission in 4K HDR with minimal lags (50–70 ms).

To cast your screen:

1. Make sure your TV and iPhone are connected to the same Wi-Fi network.
2. On iPhone, swipe down from the top-right corner (control center).
3. Click Screen mirroring (or Screen Mirroring).
4. Select your TV from the list. If prompted, enter the PIN code on the TV screen.

For broadcast video only (without duplicating the entire screen) use the AirPlay icon in supported apps (YouTube, Apple TV+, Photos). This will reduce the load on the phone's processor.

Why can't AirPlay find my TV?

If your TV doesn't appear in the list of AirPlay devices, check:

1. Network settings: Some routers block the Bonjour protocol (required for AirPlay). Enable it in the router's admin panel (section LAN → Multicast).

2. Firewall: antiviruses (for example, Kaspersky) may block data transfer. Add an exception for the app. AirPlay.

3. Firmware version: on TVs Samsung An update is required before 2020 Tizen 5.0+ to support AirPlay 2.

4. Third-party apps: when built-in features aren't enough

If built-in protocols don't work (for example, on older TVs or uncertified devices), use third-party apps. We tested five popular solutions and selected the best ones based on stability and functionality:

Important: Most applications require the server part to be installed on the TV. Android TV This is an APK file that can be downloaded from the official website (for example, ApowerMirror for TV). On Samsung/LG with proprietary OS you will have to use Send Files to TV or similar.

⚠️ Warning: Apps like TeamViewer They transmit data through external servers, which may compromise privacy. Do not use them to transmit personal data (passwords, banking apps).

5. Optimize your Wi-Fi network for uninterrupted streaming

Even the most advanced wireless broadcast protocol will slow down if the Wi-Fi network is overloaded. Here are the key settings you need to configure on your router:

• 📶 5 GHz band: Use it instead of 2.4 GHz - less interference and higher throughput. On routers ASUS And TP-Link turn on 80 MHz Channel Width in the wireless network settings.
• 🔒 Qos (Quality of Service): Prioritize traffic for devices participating in the broadcast. Keenetic this is done in the section Home Network → Traffic Prioritization.
• 🔄 Turn off energy saving: On your smartphone, in the Wi-Fi settings, turn off the option Adaptive Wi-Fi or Saving battery on Wi-Fi - It disconnects when idle.

To test network stability, use the app WiFi Analyzer (Android) or NetSpot (iOS). Optimal broadcasting parameters:

• Speed: not less than 20 Mbps (For 1080p) or 50 Mbps (For 4K).
• Ping: less 20 ms to the router.
• Packet loss: no more than 1%.

6. Solving common problems

Even with the correct settings, errors can still occur. Here are typical scenarios and how to resolve them:

If the problem persists, check error log on TV. On LG he is in Settings → General → System Logs, on Samsung - V Support → Self-diagnosisLook for error codes related to WiFiDisplay or Miracast.

7. Alternative methods: when Wi-Fi isn't suitable

If wireless streaming is not possible due to technical limitations (e.g. on TVs prior to 2016), consider alternatives:

• 🔌 HDMI adapter: For Android — USB-C to HDMI (supports 4K@60Hz), For iPhone — Apple Lightning Digital AV Adapter (Max. 1080p). Delay: 10–30 ms.
• 📶 Wi-Fi Direct + DLNA: Some TVs (Sony, Philips) support the protocol DLNA to transfer media files without screen mirroring.
• 🖥️ PC as an intermediary: Install on your computer ApowerMirror or 5KPlayer, connect the TV via HDMI, and stream your phone to your PC via Wi-Fi.

For gamers who are sensitive to latency, it is optimal USB-C/HDMI adapter - it provides minimal lag and stable 60 FPSHowever, for watching movies or presentations, Wi-Fi methods are sufficient.
