    "No sound" during broadcast Incompatible audio codec (DTS, TrueHD) Recode the file to AAC or MP3 by using HandBrake
    Video lag and stuttering Weak Wi-Fi signal or network congestion Switch the router to a channel 5 GHz with width 80 MHz or use Ethernet-TV adapter
    "Resolution not supported" The TV does not support 4K@60Hz via Wi-Fi Set the resolution on your PC 1920×1080@60Hz in the screen settings
    Application Steam Link doesn't start Outdated TV or Steam firmware Update your TV software and Steam to the latest version

    8. FAQ: Frequently Asked Questions

    Can I connect an old PC without Wi-Fi to a TCL TV?

    Yes, but it will be required Wi-Fi adapter (For example, TP-Link TL-WN725N for ~500 ₽) or Powerline adapter (for transmitting internet through electrical wiring). You can also use HDMI-cable with USB-Wi-Fi set-top box (For example, Microsoft Wireless Display Adapter).

    Why does the picture lag when connecting via Miracast?

    Reasons:

    • Weak processor/graphics card on PC (especially on Intel Atom or AMD APU).
    • Congested Wi-Fi network (many connected devices or neighboring networks on the same channel).
    • Low router bandwidth (e.g. standard 802.11n instead of 802.11ac).

    Solutions:

    • Reduce your PC screen resolution to 1280×720.
    • Connect the router to the TV via cable (Ethernet).
    • Turn on the mode "Game" on the router (if supported).
    How to screencast from macOS to TCL without AirPlay?

    If your TV does not support AirPlay, use:

    • Google Cast: Install Google Chrome and broadcast the tab.
    • Miracast: Programs AirParrot 3 or Reflector (paid).
    • DLNA: Set up Plex Media Server or Kodi.

    Suitable for games Steam Link or Moonlight (for broadcasting from PC to NVIDIA GPU).

    Is it possible to connect a phone to a TV via the same Wi-Fi as a PC?

    Yes, but only one connection can work at a time (for example, either a PC Miracast, or phone by Google Cast). To broadcast simultaneously from multiple devices, you will need:

    • 📱 Use HDMI switch (for wired connection).
    • 🖥️ Set up DLNA server on PC and stream from your phone via VLC or BubbleUPnP.

    • 🎵 In your PC settings, select the audio format PCM or Dolby Digital (instead of compressed AAC).
    • 📶 Use Wi-Fi 6 (802.11ax) to reduce packet loss.

    If the audio lags behind the video, reduce buffering in the protocol settings (for example, in Steam Link or Kodi).
