Broadcasting movies and videos from Android smartphone to a large TV screen via Wi-Fi is a convenient way to enjoy content without unnecessary wires. But it is not always obvious which method to choose: built-in functions like Miracast or Google Cast, third-party applications like LocalCast, or proprietary technologies from Samsung, LG and Xiaomi. Each option has its own nuances - from support for video formats to connection stability.

In this article we will analyze all current methods of wireless broadcasting from Android to TV via Wi-Fiincluding step-by-step guide for popular TV brands, comparison of technologies in terms of transmission speed and quality, as well as solutions to problems such as sound delay or connection loss. We will pay special attention to compatibility with different versions Android (from 8.0 to 14) and TV models (including budget Smart TV without built-in Chromecast).

If you have previously encountered that the video “slows down” during broadcast or the TV simply cannot be seen by the phone - here you will find proven ways to eliminate such problems. And for those who are looking for maximum quality, we tested the transmission 4K HDR through different protocols and prepared a comparison table.

  • 🔄 Enabled Wi-Fi and (if necessary) Bluetooth —some protocols use it for initial synchronization.
  • 🔋 Battery charge is at least 30% —video broadcast consumes energy faster than normal viewing.
  • 📶 Homogeneous network: the phone and TV must be connected to one Wi-Fi network (exception - Miracastwhich creates a direct connection).

TV requirements:

  • 📺 Smart TV with support for at least one of the technologies: Miracast (Wireless Display), DLNA, Google Cast (built-in or via Chromecast), AirPlay (for Apple TV), Samsung Smart View, LG Screen Share.
  • 🔄 Updated software: check for updates in the menu Settings → Support → Software update.

2. Method 1: Miracast (Wireless Display) - direct broadcast without a router

Miracast is a wireless screen transfer standard that works without connecting to a router. The phone and TV are connected directly via Wi-Fi Direct, which eliminates delays due to routing through the network. most Android devices (starting from version 4.2) and Smart TV (except some models Apple TV).

  • 🎮 Supports audio and control transmission (for example, for presentations).

Disadvantages:

  • 📶 Limited range (up to 10 meters without obstacles).
  • 🔋 Increased phone battery consumption.
  • 🖥️ Not all applications support transmission via Miracast (for example, Netflix and YouTube can block output by DRM).

Connection instructions:

  1. On the TV, activate the mode Miracast (names may differ):
    • Samsung: Settings → General → External devices → Screen Mirroring.

    4. Method 3: DLNA - transfer of local files without screen duplication

    DLNA (Digital Living Network Alliance) - a protocol for exchanging media files between devices on a local network. Unlike Miracast i Google Cast, here the phone acts as a server, and the TV acts as a client that “pulls” the file directly. This is ideal for watching local videos (recorded on the phone or downloaded), but does not work with streaming services.

    If the TV does not see the phone on the network DLNAcheck:

    • Whether power saving modes are disabled on the phone (they can block background transmission data).
    • Are the settings Android allowed for transferring files over a local network (Settings → Applications → Special access → Local network access).
    • Is the transfer blocked by an antivirus or VPN.
    How to convert video for DLNA

    If your TV does not support the file format (for example.mkv with DTS), use the app HandBrake (free) to convert to MP4 (H.264 + AAC)Settings:

    - Format: MP4

    - Video codec: H.264

    - Audio codec: AAC

    - Resolution: 1920×1080 (if the TV does not support 4K)

    5. Method 4: Proprietary solutions. from manufacturers (Smart View, Screen Mirroring)
