2. Using DLNA and LG Smart Share for media files

If you only need to stream photos, videos, or music (without screen mirroring), the protocol is optimal. DLNAOn TV LG it is implemented through an application Smart ShareThis method is less demanding on Wi-Fi speed and works even on older models (for example, LG 32LH604V 2016).

To configure:

    5. Solving typical synchronization problems

    Even with proper setup, errors can still occur. Let's look at the most common ones:

    Problem: The TV does not see the phone in the list of devices

    • 🔄 Restart both devices.
    • 📡 Check that the router is working in the mode 802.11ac (5 GHz) - some TVs LG do not support 802.11n (2.4 GHz) for Miracast.
    • 🔧 Turn it off on your phone Adaptive Wi-Fi (on Samsung) or Intelligent switching (on Xiaomi) - these functions may break the connection.

    Problem: The image is slow or choppy.

    • 📶 Switch to range 5 GHz - it is less congested and provides greater throughput.
    • 🎮 Reduce the broadcast resolution in Miracast settings (if available) to 720p.
    • 🔌 Connect your TV to your router via Ethernet (if there is a LAN port) - this will reduce the load on Wi-Fi.

    Problem: No sound during broadcast

    • 🔊 On your TV, check that Settings → Sound → Output selected TV Speaker (and not HDMI ARC or Optical).
    • 📱 Turn off Bluetooth headphones on your phone—they can intercept the audio stream.
    • 🔄 Restart the broadcast by first turning it on on your TV Game mode (reduces audio delay).

    6. Optimize your Wi-Fi network for stable streaming

    Synchronization quality directly depends on your router settings. The following settings will help avoid stuttering and interruptions:

    • 📶 Wi-Fi channel: Select the least crowded channel in the range 5 GHz (For example, 36, 40, 44 or 48). Use the app WiFi Analyzer for ether analysis.
    • 🔒 Encryption: Install WPA2-PSK (avoid WPA3 on older models LG - there may be compatibility issues).
    • 📦 QoS (Quality of Service): In your router settings, prioritize traffic for the TV's MAC address.
    • 🔄 Opening hours: Turn it off 802.11r (Fast Roaming) - It can cause connection breaks when broadcasting.

    For routers TP-Link path to QoS settings:

    Advanced settings → QoS → Rule settings → Add new rule
    

    Priority: High

    MAC Address: [your LG TV's address]

    Port: 7000, 5353 (for AirPlay/Miracast)

    If your router does not support 5 GHz, consider purchasing an inexpensive model with support 802.11ac (For example, Xiaomi Mi Router 4A or TP-Link Archer C6). The difference in speed between 2.4 GHz And 5 GHz when broadcasting video 4K can reach 10 times!

    7. Comparison of connection methods: which one to choose?

    Method Supported devices Delay Video quality Difficulty of setup
    Miracast (Screen Share) Android 4.2+, Windows 10 50–100 ms Up to 4K/30fps ⭐⭐
    DLNA (Smart Share) Android, iOS, PC 200–500 ms Up to 1080p
    Apple AirPlay 2 iPhone/iPad (iOS 12+) 30–80 ms Up to 4K/60fps (HDR) ⭐⭐
    Wi-Fi Direct Android, some iOS 100–200 ms Up to 1080p ⭐⭐⭐
    Third-party applications Android, iOS 50–300 ms Depends on the software ⭐⭐⭐⭐

    The choice of method depends on your goals:
