To activate Miracast on TV LG, follow these steps:

  • 📺 Turn on your TV and go to Settings → Connections → Screen Share.
  • 🔄 Select a mode "Miracast" (on some models it may be called "Wi-Fi Direct").
  • 🖥️ On your computer, click Win + K (or open Settings → System → Project to this PC).
  • 🔍 Select the name of your TV from the list of available devices LG (For example, LG_OLED55C1).

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

  • 🔌 Both devices are connected to one Wi-Fi network (or use Wi-Fi Direct for direct connection).
  • 🔄 The TV is in the "Standby" mode. "Allow connection" in the settings Screen Share.
  • 🖥️ The wireless adapter drivers on the PC have been updated (especially if you are using Intel Wi-Fi 6 or Realtek).

Both devices are on the same network | Wi-Fi drivers are updated on the PC | Screen Share is enabled on the TV | VPN and firewalls are disabled -->

Typical errors and solutions:

  • ❌ "Device not supported" - update your TV firmware via Settings → General → Software Update.
  • ❌ "No sound" - V Windows go to Sound Options → Output and select TV as the default device.
  • ❌ Image Delay - Reduce the screen resolution on your PC to 1920×1080 or disable background apps.

2. Using DLNA to stream media files

Protocol DLNA intended for transmission photos, videos and music From your computer to your TV without screen mirroring. This method is suitable if you just need to play a movie or show photos, but not play games or work with apps. The advantage DLNA - support by almost all models LG (even old ones, on NetCast) and low network load.

For setup DLNA on TV LG:

  1. Install a server program on your PC, for example, Plex Media Server, Kodi or built-in Windows Media Player (For Windows 10/11).
  2. On your TV, open the app LG Media Player (or Photos & Videos on new models).
  3. In the list of sources, select your computer - it should appear as DLNA server.

Comparison of popular DLNA servers:

Program Format support Transcoding Mobile access
Plex All popular (MKV, MP4, FLAC) Yes (automatically) Yes (via app)
Kodi Limited (requires plugins) No No
Windows Media Player Basic (MP4, JPEG, MP3) No No
Serviio Extended (including ISO) Yes (configurable) Yes

If the TV does not see the DLNA server:

  • 🔌 Make sure your computer and TV are in the same subnet (for example, both are connected to the router, and not to different repeaters).
  • 🔒 Disable your firewall or add an exception for the server program (ports 1900/TCP And 5556/TCP).
  • 📡 Check that it is enabled in your router settings Multicast (needed to detect DLNA devices).
Why is DLNA lagging when playing 4K?

When streaming high-definition video (4K HDR) via DLNA, lag may occur due to Wi-Fi bandwidth limitations. Solutions:

1. Connect the TV to the router via cable (if possible).

2. Reduce the video bitrate to 20–30 Mbps (for example, via HandBrake).

3. Use a router that supports Wi-Fi 6 (802.11ax) for stable transmission.

If you want to play on the big screen without wires, Steam Link — one of the best solutions. This method is suitable for TVs LG With webOS 4.0+ (2018 and newer) and requires the app to be installed Steam Link from LG Content StoreThe main advantage is optimized streaming with minimal latency (up to 10–20 ms with good Wi-Fi), gamepad support, and bitrate customization.

Step-by-step instructions:

  1. Install Steam Link to TV via LG Content Store.
  2. Run on PC Steam and go to Settings → Remote Play.
  3. Enable the option "Turn on streaming" and add the TV to the list of trusted devices.
  4. Open on your TV Steam Link, select your PC and connect the gamepad (via Bluetooth or USB).

Recommended settings for stable streaming:

  • 📶 Use 5 GHz Wi-Fi (channels 36-48 for minimal interference).
  • 🎮 In the settings Steam Link set the bitrate 20–30 Mbps (for 1080p) or 50+ Mbps (for 4K).
  • 🖥️ On your PC, disable background programs that consume network bandwidth (torrents, cloud synchronization).

Common problems and solutions:

  • ❌ "No sound" — in the settings Steam Link select "Transmit audio to device".
  • ❌ Image stuttering — Reduce the resolution in the stream settings or connect the TV to the router with a cable.
  • ❌ "The gamepad won't connect." - update the TV firmware and check the controller compatibility (for example, Xbox Series X works without problems, and DualSense may require an adapter).
📊 What resolution are you using for Steam Link?
720p (acceptable)
1080p (optimal)
1440p (requires good Wi-Fi)

6. Optimize your Wi-Fi network for stable streaming

The quality of your wireless connection directly impacts the smoothness of your stream. Even if you're using a modern router, incorrect settings can cause lag or connection drops. Below: key parameters, which need to be checked.

1. Selecting the Wi-Fi range and channel:

  • 📶 To broadcast video, use 5 GHz - it is less congested and supports higher speeds.
  • 🔄 In manual mode, select a channel with minimal interference (for example, 36, 40, 44 or 48).
  • 📊 Check channel load using apps like Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS).

2. Router settings for minimal delays:

  • 🔧 Turn on QoS (Quality of Service) and set the highest priority for devices LG TV And PC.
  • 🔄 Turn it off Band Steering (if the router supports it) - sometimes it forces devices to switch to 2.4 GHz.
  • 📦 Set a fixed channel width 40 MHz (For 5 GHz) instead of automatic mode.

3. Checking the connection speed and stability:

  • 📈 Run a speed test between your PC and TV using iPerf3: 
    iperf3 -s

    (on TV through Termux or a PC on the same network).

  • 🔌 If the speed is lower 50 Mbps, check:
    • The distance between the router and devices (optimally no more than 5 meters without obstacles).
    • There is interference from other routers (use channels 149–165 for minimal overlaps).

Recommended routers for wireless streaming:

Router model Wi-Fi standard Max. speed (5 GHz) QoS support
ASUS RT-AX88U Wi-Fi 6 4804 Mbps Yes (Adaptive QoS)
TP-Link Archer AX6000 Wi-Fi 6 4804 Mbps Yes (HomeCare)
Netgear Nighthawk RAXE500 Wi-Fi 6E 10800 Mbps Yes (DumaOS)
Keenetic Ultra II Wi-Fi 6 2400 Mbps Yes (Traffic prioritization)

7. Connecting macOS to an LG TV: Features and Solutions

Users MacBook or iMac often face limited support Miracast V macOSApple uses its own protocol. AirPlay, which is supported only by TVs LG With webOS 5.0+ (2020 and newer). If your model is older, you'll have to use alternative methods.

Method 1: AirPlay (for webOS 5.0+)

  • 🍎 On TV: Settings → General → Apple AirPlay and HomeKit → Enable AirPlay.
  • 🖥️ On Mac: Open Control Center → Screen Mirroring and select TV.
  • 🔊 To transmit sound, turn on "Use as a separate display".

Method 2: Third-party applications

  • 📱 ApowerMirror — supports screen mirroring, but with a delay of ~200 ms.
  • 🎮 Moonlight - optimal for gaming (requires NVIDIA GPU on PC).
  • 📺 JustStream - video broadcasting via DLNA (without screen duplication).

Method 3: Windows Virtual Machine (for Miracast)

  • 🖥️ Install Windows 10/11 through Parallels Desktop or VMware Fusion.
  • 🔄 In the virtual machine settings, enable 3D acceleration and transmission Wi-Fi adapter.
  • 📺 Connect via Win + K just like on a regular PC.
Why does AirPlay work worse on LG TV than on Apple TV?

LG TVs use a software implementation of AirPlay that is less optimized than the hardware solution in Apple TV. This results in:

- Higher latency (100-200ms vs. 30-50ms on Apple TV).

- Occasional artifacts when playing 4K HDR.

- Limited format support (for example, no Dolby Vision via AirPlay).

Troubleshooting macOS:

  • ❌ "No sound when mirroring" - V macOS Sound Settings select Built-in output instead of TV.
