1. Preparation of the Xiaomi Mi TV 4S to connect

Before connecting devices, make sure the TV is ready for wireless connection. On the Mi TV 4S (Models 43, 50, 55" and 65), the setup process is the same, but may vary depending on the PatchWall firmware version (update it in advance in Settings → About TV → Software Update).

Turn on the TV and follow the following steps:

• 📶 Activate Wi-Fi: Go to Settings → Network and Internet → Wi-Fi and connect to your home network. Without that, Wi-Fi Direct and DLNA will not work.
• 🔄 Update your firmware: outdated software often causes connection failures. → About TV, check the relevance of the version.
• 🛡️ Turn it off. VPN/Proxy: If additional networks are enabled on the TV or router (such as Pi-hole), they can block device detection.
• 🔍 Reset network settings (if necessary): If you have previously had connection problems, reset to Settings → Network and Internet → Additionally. → Resetting network settings.

⚠️ Attention: If your Mi is yours TV 4S If you can't see the Wi-Fi network, check your router settings. Some models (e.g. TP-Link Archer) C6) By default, the network is hidden in the 5 GHz band, and the TV can only search 2.4 GHz. Switch the router to 2.4 GHz mode or enable support for both bands.

After you've prepared the TV, you can start by choosing the connection method, starting with the most universal one, Wi-Fi Direct.

2. Method 1: Connect via Wi-Fi Direct (direct connection)

Wi-Fi Direct allows you to connect your phone and TV directly, without a router, a method that is suitable for transferring files, streaming videos from a gallery or watching online content (for example, from Kodi or VLC), the main advantage is a stable connection even with a weak home Wi-Fi signal.

Instructions for Android smartphones:

1. On TV: open Settings → Devices and Accessories → Wi-Fi Direct and turn on the function. Remember the network name (e.g. DIRECT-MiTV4S-XXXXX).
2. On your smartphone: go to Settings → Connections → Wi-Fi (on Samsung) or Settings → Network and Internet → Wi-Fi (only) Xiaomi/Google Pixel).
3. Find the network with your TV name (starts at DIRECT-) and connect to it. Password is not usually required, but if it does, type 12345678 or 00000000.
4. Run a live streaming app (such as LocalCast or BubbleUPnP) and select the TV as the output device.

For iPhone, Wi-Fi Direct is not directly supported, but you can use a workaround via DLNA (discussed below) or special applications like Screen Mirroring for Xiaomi TV (available from the App Store).

⚠️ Warning: If the TV flashes or brakes after you connect, try to reduce the resolution in the application settings. TV 4S — 1280×720 frequency-wise 30 Hz.

3. Method 2: Mirroring the screen through Miracast

Miracast is a wireless backup technology that works without the Internet, ideal for presentations, games or photo displays, and on the Xiaomi Mi TV 4S, the feature is built into the firmware, but on a smartphone, you need to activate it manually.

Step-by-step:

• 📺 On TV: Go to Settings → Screen. → Wireless display (Miracast) and turn on the option. Remember the name of the device (for example, MiTV4S-55).
• 📱 On Android: Open Settings → Connected devices → Wireless display (on Xiaomi the path may be different: Settings) → Screen. → Wireless monitor: Choose your TV from the list.
• 🍎 On iPhone, use Screen Mirroring (to Control Point). TV 4S does not support AirPlay directly – you will need to install third-party software (for example, ApowerMirror).

Once successfully connected, the smartphone screen will be completely duplicated on the TV. Lag is usually 50-150 ms, which is noticeable in games, but not critical for video.

Method 3: Translating Media Through DLNA (UPnP)

DLNA is a standard for transmitting music, videos and photos over a local network, and unlike Miracast, it doesn't duplicate a screen, it only broadcasts media, and it's a method that's suitable for watching movies from a phone gallery or streaming from YouTube, Twitch.

How to set up:

1. On TV: turn it on DLNA-server settings → Annexes → Media server: Make sure that the TV and phone are connected to the same Wi-Fi network.
2. On a smartphone: install a player app with support DLNA, for example: 🎬 VLC (Free, supports all formats) 📺 LocalCast (convenient interface for broadcasting) 🎵 BubbleUPnP (for music and playlists)

Mi TV 4S

Important: To stream MKV or AVI video, the TV must support H.265 and AC3 codecs. If the video is not played, convert it to MP4 (H.264) using HandBrake.

💡

If the TV can't see the phone through DLNA, check the firewall settings on the router. Some models (like Keenetic) block UPnP by default. Go to the router's control panel and turn on the Multimedia option (DLNA/UPnP).

5. Solving Connection Problems

Even if you set it up properly, you can have failures, and let's look at some of the most common errors and how to fix them.

Problem 1: The TV doesn’t detect the smartphone

• 🔌 Check that both devices are connected to the same Wi-Fi network (even Wi-Fi Direct sometimes requires a preconnection to the router).
• 🔄 Reboot the TV and phone. TV 4S Press the power button on the remote for 5 seconds.
• 📱 On your smartphone, turn on the developer mode and activate the option Debugging over Wi-Fi (in Settings). → The phone. → Press the build number 7 times, then return to Settings → System system → For developers).

Problem 2: Sound is there, but no image (or vice versa)

• 🔊 Check the sound settings on the TV: go to Settings → Sound. → The exit port and select TV-dynamics.
• 🖥️ If the image is missing, try changing the broadcast resolution in Miracast settings (optimally: 1280×720).
• 🔌 Disable all additional devices from HDMI-TV ports – they may conflict with wireless broadcasting.

Problem 3: Lags and stutters when watching videos

• 📶 Check Wi-Fi Speed: For Full Broadcasting HD You need at least 10 Mbps. Use the Speedtest app to measure.
• 🔄 Switch the router to a 5GHz channel (if supported) – it’s less busy than 2.4GHz.
• 📱 Close background apps on your smartphone that consume the Internet (for example, Telegram or TikTok).

💡

If neither method works, check your smartphone’s compatibility with Mi TV 4S protocols. For example, iPhones older than the iPhone 6 don’t support Miracast, and some Realme and Oppo models require manual Wi-Fi Display activation in the engineering menu.

6. Alternative ways of connecting

If wireless methods are not suitable (for example, due to poor Wi-Fi), consider alternatives:

Connection via HDMI (with adapter)

• 📱 For Android: Use an Adapter USB-C/Micro-USB → HDMI (For example, Xiaomi Mi USB-C to HDMI). Price: from 1 500 ₽.
• 🍎 For iPhone: You need a Lightning adapter → HDMI (Apple's official is ~4 000 ₽).

Advantage: zero latency and maximum quality (4K@60Hz) Disadvantage: wires limit mobility.

2 Use of Google Chromecast or Xiaomi Mi TV Stick

• 📺 Connect Mi. TV Stick to HDMI-port the TV and set it up as a separate device.
• 📱 On your smartphone, use the Google Home app to stream content.

Plus: Google Cast supports and even works with iPhone (~3 000 ₽).

3. Remote management applications

• 🎮 TeamViewer QuickSupport – to control the TV from your phone (useful for setting up).
• 🖱️ Unified Remote – turns your smartphone into a touchpad remote.

7. Optimization of broadcasting for games and video

If you’re connecting a smartphone to play games (like Genshin Impact or Call of Duty Mobile), it’s important to minimize latency.

• 🎮 Use the game mode on the TV: Settings → Picture → Image mode → This reduces input lag to 20 to 30 milliseconds.
• 📶 Connect the router to the TV via cable (if possible) – this will stabilize the connection.
• 🔋 Close all background processes on the phone and turn on Do Not Disturb mode.
• 🔄 In Miracast settings, select Performance over Quality.

To watch high quality video (4K HDR):

• 🎥 Use applications with support DLNA and H.265 (for example, MX Player or Kodi).
• 🔊 Turn on Dolby Audio in the TV settings: Settings → Sound. → Sound format → Dolby Digital.
• 📡 If the video slows down, reduce the bitrate in the player settings (optimum: 8-12 Mbit / s).
