Wirelessly connect your laptop to your TV LG Wi-Fi opens up a ton of possibilities, from watching movies on a big screen to presenting without the hassle of wires. However, many users encounter difficulties—the TV doesn't detect the laptop, the image lags, or the sound cuts out. In this article, we'll look into these issues. all current connection methods (including hidden functions WebOS), we will compare them in terms of speed and stability, and also give concrete solutions for 90% of errors connections.
The main difference between a Wi-Fi connection and HDMI is flexibility and absence of wires, but this comes at the cost of potential delays and dependence on network quality. We tested the methods on models LG OLED C2, NanoCell 90 and budget series UK6200 — the results are summarized in the comparison table below. If your TV was released before 2018, some features (e.g. Miracast) may be missing - check this in the menu Settings → All settings → Network.
Let us warn you right away: for stable operation Necessarily Both the laptop and the TV need to be connected one Wi-Fi network (Not to different 2.4/5 GHz bands of the same router!). If you have a dual-band router, prioritize the network 5 GHz - it is less susceptible to interference, which is critical for video transmission 4KNow let's move on to specific methods.
1. Connecting via Miracast (Screen Share) is the most universal method
Miracast - is a wireless screen sharing standard that is supported by almost all modern laptops Windows 10/11 and televisions LG With WebOS 3.0 and newer. Its main advantage is minimal delays (about 30-50 ms), which allows you to comfortably play games or work with presentations.To activate Screen Share on TV LG, follow these steps:

On a laptop with Windows:
- Press the combination
Win + K(or openSettings → System → Display → Connect to a wireless display). - Select your TV from the list of available devices. LG (the name will be displayed as the model, for example, LG OLED55C1).
- Confirm the connection on both devices.
If your TV does not appear in the list, check:
- 🔄 Restart both devices - sometimes this solves the detection issue.
- 📶 Make sure your laptop and TV are connected to the same Wi-Fi network (even if Miracast works without a router, for LG (This is mandatory).
- 🔧 Update your laptop's Wi-Fi adapter drivers (especially important for older models) Intel or Realtek).
The laptop and TV are on the same Wi-Fi network | Miracast is enabled in the TV settings | The Wi-Fi drivers on the laptop are updated | VPN and firewalls are disabled -->
⚠️ Attention: On laptops with AMD Ryzen (especially the 4000/5000 series) may experience artifacts when transmitting video via Miracast. The solution is to disable the option in the graphics driver. Variable Refresh Rate or update the TV firmware.
A critical detail: LG TVs with WebOS 4.0 and newer support Miracast only in point-to-point mode (without a router), but for stability, it is better to use a shared network. If the image is lagging, try reducing the laptop screen resolution to 1920×1080 or disable background apps that consume traffic.
2. Using DLNA/UPnP to transfer media files
If you don’t need to duplicate the screen, but simply broadcast movies, music or photos from your laptop to your TV, then DLNA (or Smart Share in terminology LG) is the optimal choice. This protocol allows for lag-free streaming of content, but does not support desktop duplication.

- Open
Settings → Network & Internet → Sharing options. - Turn on
Network discoveryAndFile and Printer Sharing. - Add folders with media files to shared access (right click →
Properties → Access).
For users macOS or Linux you will need to install additional software, for example, MiniDLNA or Plex Media ServerThe main advantage of DLNA is no binding to the operating system, the main thing is that the devices are on the same network.

- Maximum resolution for MKV is 1080p (4K requires conversion)
If the TV doesn't see folders from the laptop:
- Check that the laptop is turned on.
File and Printer for Microsoft Networks(VNetwork Connections → Adapter Properties). - Disable your firewall Windows Defender or antivirus for 5 minutes - they can block access.
- Make sure that the IP addresses of your laptop and TV are in the same subnet (e.g.
192.168.1.x).
⚠️ Attention: When streaming movies in4K HDRDLNA may cause slowdowns if the router does not support the standards802.11ac(Wi-Fi 5) or higher. Solution: Connect your TV to the router with a cable.Ethernet, and leave the laptop on Wi-Fi.

1. Selecting a Wi-Fi band:
5 GHz— priority for video transmission (less interference, higher speed).2.4 GHz- only if5 GHzIt doesn't work or the TV doesn't support it.
2. Channel and bandwidth:
- In your router settings, select a channel with minimal traffic (use apps like Wi-Fi Analyzer).
- For
5 GHzset the channel width80 MHz(if the router supports it).
3. Router location:
- 📡 The router should be located at an equal distance from the laptop and TV.
- 🚫 Avoid obstacles (walls, metal objects) in the signal path.
Recommended router settings for streaming:
| Parameter | Recommended value | Explanation |
|---|---|---|
| Wi-Fi standard | 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) |
Provides speeds of 400 Mbps |
| Channel width | 80 MHz (for 5 GHz) |
Increases throughput |
