How to Mirror Your Phone to TV via Wi-Fi: A Complete Guide

Streaming content from your phone to a big TV screen via Wi-Fi has become a standard feature of modern devices, but not all users know how to set up this connection correctly. Depending on the smartphone model (Android or iPhone) and TV (Samsung, LG, Sony Bravia or Xiaomi TV) different protocols are available: from built-in Miracast to proprietary solutions like AirPlay (For Apple) or Google Cast (For Android). The main advantage of wireless broadcasting is the absence of wires and the ability to control content directly from a smartphone, but the quality of the transmission depends on the stability Wi-Fi networks and supported codecs.

In this article, we'll explore all the current methods of screen sharing over Wi-Fi, including their pros and cons. You'll learn how to set up streaming using your TV's standard features, which apps can help bypass manufacturer restrictions, and why video sometimes lags or displays artifacts. We'll also cover the nuances for devices without Wi-Fi. Smart TV (using prefixes like Amazon Fire Stick or Xiaomi Mi Box) and we will give recommendations on optimizing the network for smooth broadcasting in resolution 4K.

1. Screen Transfer Methods: Comparison of Technologies

All wireless broadcast methods can be divided into two groups: built-in protocols (supported out of the box) and third-party solutions (require app installation). The main differences between them are data transfer speed, audio support, and compatibility with different brands of devices.

• 🔄 Miracast — a universal standard for Android And Windows, works without the Internet (direct connection) Wi-Fi Direct). Supports resolution up to 1080p, but may slow down when the signal is weak.
• 🍎 AirPlay — proprietary protocol Apple for broadcasting with iPhone/iPad on Apple TV or compatible TVs (Samsung, LG since 2018). Quality up to 4K HDR, but requires devices with a chip Apple A8 and newer.
• 📱 Google Cast - technology from Google for streaming content (not the entire screen!) with Android on Chromecast or Android TVIt works via the cloud, so it depends on your internet speed.
• 🌐 DLNA/UPnP — an outdated protocol for transferring media files (photos, videos, music) over a local network. Doesn't support real-time screen sharing.
• 🛠️ Third-party applications - For example, ApowerMirror, TeamViewer or LetsViewThey often offer additional features (screen recording, annotations), but may charge for premium versions.

The choice of technology depends on your devices. For example, for broadcasting from iPhone 13 on Samsung QLED 2023 optimal AirPlay, and for Xiaomi Redmi Note 12 And LG OLED C2 — Miracast. If you only need to transmit video (for example, with YouTube), enough Google Cast.

⚠️ Attention: TV manufacturers often limit protocol support depending on the region of sale. For example, Samsung can turn off Miracast in US models, but retain it in European versions. Please check the specifications on the official website before purchasing.

2. Preparing devices: what to check before connecting

Before setting up a stream, make sure both devices meet the minimum requirements. The key requirements for a successful connection are:

• 📶 Wi-Fi network: Both devices must be connected to the same network (for Miracast And Wi-Fi Direct - a direct connection is sufficient). Recommended speed: not less than 10 Mbps For 1080p And 25 Mbps For 4K.
• 🔋 Battery charge: Your smartphone should have at least 30% battery—screencasting drains power. For extended use, connect your phone to a charger.
• 📱 OS version: On Android version 4.2 and above is required iOS — 12.0+. For AirPlay 2 needed iPhone 8 or newer.
• 📺 TV model: Make sure yours is Smart TV supports the selected protocol. For example, LG WebOS until 2016 does not work AirPlay.

If you use Wi-Fi Direct (For Miracast), turn off mobile internet on your phone - this will eliminate possible network conflicts. Also check if it's blocking firewall or antivirus data transfer over a local network.

⚠️ Attention: On some TVs Sony Bravia 2017–2019 release function Miracast hidden in the developer menu. To activate it, go to Settings → Network → Advanced → Wi-Fi Direct Settings and turn on the mode Display.

3. Stream from Android to Smart TV via Miracast

Miracast — the most universal way for Android-devices, as it doesn't require a connection to a router.

Step-by-step instructions:

1. Make sure that iPhone and the TV are connected to the same Wi-Fi network. Turn on the TV AirPlay:
   • For Samsung: Settings → General → Apple AirPlay → enable the option.
   • For LG: Settings → Network → AirPlay.
   • For Apple TV: The function is enabled by default.

On iPhone swipe down from the top right corner of the screen to open Control center.

Click on the icon Screencasting (two rectangles with a triangle).

Select the name of your TV from the list. When connecting for the first time, you may be asked to enter the code displayed on the TV screen.

5. Using Google Cast and Chromecast

Google Cast differs from Miracast in that it does not broadcast the entire screen, but only content from supported applications (for example, YouTube, Netflix, Google Photos). This reduces the network load, but limits functionality. For full screen sharing, you will need Chromecast or TV with Android TV.
