Do you want to show photos from your vacation on the big screen, play a movie from your phone on your TV, or hold a presentation without an HDMI cable? Broadcasting video from an Android smartphone to TV opens up a lot of possibilities - from watching Netflix in high definition to streaming games with minimal latency. But how to choose the best method among dozens of technologies if you TV on Android TVand your phone is on a standard version of Android?

In this article we will look at 7 working methods image transmission - from wireless protocols (Miracast, Google Cast) to wired solutions (USB-C → HDMI). You will learn which option is suitable for your TV model (Samsung, LG, Xiaomi etc.), how to avoid common mistakes (for example, audio delay when broadcasting via Wi-Fi Direct) and what settings you need to change on your phone for stable operation. And if you are faced with the problem of “no sound” or “black screen,” there is a section with solutions at the end of the article.

It doesn’t matter whether you want to duplicate the screen for games, broadcast YouTube in 4K or just show the video to relatives - here you will find step-by-step guide with illustrations (in the form of a text description) and a comparative table of methods. Let's start with the most universal method - Miracastwhich works on 90% of modern devices.

1. Miracast: wireless broadcast without a router

Miracast is a wireless video transmission standard built into most Android devices starting from version 4.2. It allows you to duplicate your phone screen onto your TV without an Internet connectionusing technology Wi-Fi Direct. The main advantage is the absence of delays (latency up to 30 ms), which is critical for games or video chats.

To activate Miracast, follow these steps:

  • 📱 On the phone: open Settings → Connections → Screen Sharing (on Samsung) or Settings → Display → Wireless Display (on "pure" Android). Turn on the function.
  • 📺 On TV: go to Settings → Network → Miracast or Display → Wireless display. Activate connection standby mode.
  • 🔍 In the list of available devices on your phone, select the name of your TV (for example, LG OLED55C1). Confirm the connection on both devices.

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

  • ⚡ Both devices support Miracast (on phones Huawei before 2019, the application may be required Huawei Share).
  • 📶 The mode is turned on on the TV Wi-Fi Direct (sometimes hidden in the menu Network → Advanced).
  • 🔄 Restart both devices - this resets the network connection cache.

Philips
Other
⚠️ Attention: On TVs Samsung 2018–2020, Miracast may work unstable due to firmware limitations. In this case, use Smart View (Samsung proprietary application) or Google Cast.

Miracast supports resolution up to 1080p at frequency 60 Hz, but on some TVs (for example, Sony Bravia X90J series) the quality may be reduced to 720p with a weak signal. For stable operation, keep the devices at a distance of no more 5 meters and make sure that there are no obstacles between them (walls, furniture).

💡

Miracast is the best choice for games and video chats due to its minimal latency, but requires support on both devices.

2. Google Cast (Chromecast): streaming content through applications

If Miracast duplicates full screen the phone, then Google Cast (the underlying technology Chromecast) allows you to broadcast only video from supported applications — YouTube, Netflix, Kinopoisk etc. This reduces the load on the phone and improves picture quality (up to 4K HDR on compatible TV).

How to use Google Cast:

  1. Make sure your phone and TV are connected to one Wi-Fi network (router required!).
  2. Open an application with Cast support (for example, YouTube). Tap on the broadcast icon (📺) in the upper right corner.
  3. Select your TV from the list. If it is not there, check if it is turned on. Google Cast in the TV settings (Settings → Devices → Screen sharing).
  4. Start the video - it will play on the TV, and the phone can be used to control (pause, volume).

Advantages of Google Cast:

  • 🎬 Support 4K/60fps i HDR10 (on TVs with Android TV 9+).
  • 🔋 Minimum phone battery consumption (video is streamed directly from the Internet).
  • 🎮 Ability to broadcast games via Google Stadia or Xbox Cloud Gaming.
⚠️ Attention: Some applications (for example, TikTok or IVI) block the Cast function due to content licensing restrictions. In this case, use Miracast or HDMI.

If you have TV without built-in Chromecast (for example, old models Philips or Toshiba), buy an external adapter Google Chromecast (from 3 000 ₽). It connects to the port HDMI and adds Cast support to any TV.

3. Wired connection: HDMI via adapter

If wireless methods fail or you need maximum quality without delays (for example, to watch movies in 4K/120fps or professional video work), use wired connection via HDMIFor this you will need:

  • 🔌 Adapter USB-C → HDMI (for modern phones) or Micro-USB → HDMI (for older models).
  • 📏 Cable HDMI 2.0 or newer (for support 4K@60Hz).

Connection instructions:

  1. Connect the adapter to the phone, and the HDMI cable to the adapter and TV (the port is usually labeled HDMI 1/ARC).
  2. On the TV, select the signal source: press Source or Input on the remote control and select the appropriate HDMI port.
  3. A request for screen transfer resolution may appear on the phone - confirm it.

Important nuances:

  • 🔋 Wired connection discharges the phone faster — use charging while broadcasting.
  • 🎮 For games with gamepads (for example, Call of Duty Mobile) it is better to use HDMI 2.1 to reduce input lag.
  • 📱 On phones Samsung Galaxy S22+ and newer it is supported DeX Mode —when connected to a TV, the phone turns into a full-fledged computer with multitasking.

2. Restart the router - sometimes an IP address conflict blocks detection.

3. Update the TV firmware: on models Samsung QLED 2020 and newer Smart View only works with software. version 1600 and higher.

5. DLNA: broadcasting media files without duplicating the screen

If you do not need to duplicate full screen phones, but only broadcast video, music or photos, use the protocol DLNA. It allows you to “distribute” media files from your phone to your TV via a local network without loading the device’s processor.

How to set up DLNA:

  1. On the TV enable DLNA support: Settings → Network → DLNA Server or Multimedia → Sharing.
  2. Install the media server application on your phone, for example:
    • BubbleUPnP (for advanced users).
    • LocalCast (simple interface).
    • VLC (built-in DLNA support).
  • In the application, select files to broadcast and specify the TV as the output device.

    • Features DLNA:

    • 🎬 Supported formats: MP4, MKV, AVI, JPG, MP3.

    • ⚠️ Not all TVs support DTS or Dolby TrueHD — sound can be played back in Stereo.

    DLNA is convenient for viewing home videos or photo archives, but is not suitable for streaming from YouTube or Twitch —for this use Google Cast.

    💡

    If the TV does not see the phone via DLNA, check whether the "Media Server" mode is enabled in the router settings (usually in the section USB/Network).

    6. Third-party applications: alternative solutions

    If the built-in methods do not work (for example, on older TVs or phones with custom firmware), try applications from third-party developers. They often offer additional functions, such as recording the broadcast or transmitting audio via Bluetooth.
