Modern technology allows you to transform your TV into a fully-fledged multimedia center, but to do so, you need to properly configure the connection between your devices. If you want to stream videos, photos, or even your entire smartphone screen to a large display, you'll need a stable wireless connection. Device owners LG with support Smart TV There are several effective ways to accomplish this task without using unnecessary wires.
The basic principle is to create a local network where both devices exchange data at high speed. It's important to understand that transmission quality directly depends on the power of your router and the standard. Wi-FiIn this article, we'll cover all available methods in detail, from built-in operating system functions to specialized manufacturer-provided apps.
Before proceeding with settings, make sure your TV is connected to the internet and your smartphone is within range of a strong signal. The synchronization process typically takes no more than a couple of minutes if all parameters are configured correctly. Let's review the preparatory stage, which forms the foundation for a successful connection.
Basic requirements and equipment preparation
The first and most critical requirement is that both devices are on the same wireless network. Users often make the mistake of connecting their phone to the router's guest network or mobile 4G while the TV is connected to the main channel. Check the network name (SSID) in the settings of both devices - they must match verbatim.
The second important aspect concerns the software version. On TVs LG the current version of the platform must be installed WebOS, as older firmware may lack the necessary data transfer protocols. It's also advisable to have the latest security updates and system libraries on your smartphone.
⚠️ Important: If your router supports dual-band mode (2.4 GHz and 5 GHz), make sure both devices are connected to the same frequency. On some router models, devices on different frequencies may not be able to "see" each other for screen sharing, even if they are on the same network.
To check your equipment's readiness, you can run a simple diagnostic. Open a browser on your smartphone and try accessing any website, then check the availability of online services in the TV menu. If the internet is stable on both devices, you can proceed to choosing a streaming method.

Once the connection is established, the image from the smartphone will appear on the big screen. Please note that in this mode, the phone and TV work as a single unit: if you rotate the phone, the image will also rotate.
⚠️ Please note: When using the screen mirroring feature (Miracast), your smartphone's battery drains significantly faster than usual. It is recommended to charge your device or use an external power bank during extended sessions.

If the automatic search doesn't yield results, try manually entering the TV's IP address. You can find it in the TV's network settings: Settings → Network → Wi-Fi connection → Advanced. In the app, select "Add device manually" and enter the numbers.
Google Cast technology and Chromecast built-in
Many modern TV models LG equipped with built-in technology support Google Cast (Chromecast built-in). This is the most convenient way to watch videos from popular services like YouTube, Netflix, or Twitch, as it doesn't require mirroring your entire smartphone screen. Instead, your phone acts as a remote control, sending the TV only a link to the stream, which the TV downloads automatically.
To use this feature, make sure you have the app installed on your smartphone. Google HomeIt's the control center for all Chromecast-enabled devices. Open the app and you'll see a list of available devices on your network. If your TV LG is displayed there, which means it is ready to work.
The process of starting a broadcast is extremely simple: open the video in the YouTube app on your phone, tap the rectangle icon with waves (Cast) in the corner of the player, and select your TV. The video will begin playing on the big screen, and you can use your smartphone for other tasks or lock it—playback will not be interrupted. Picture quality is often higher in this case, since the TV decodes the stream directly.
⚠️ Please note: App and operating system interfaces are updated regularly. The location of the Cast control buttons may change. If you don't see the Cast icon, check if it's hidden in the "More" menu (three dots) or in the app's settings.
The advantage of Google Cast is its low smartphone power consumption. Since the phone doesn't encode the video stream in real time, but merely controls playback, battery life is reduced. Furthermore, image quality isn't dependent on Wi-Fi speed during transmission, as the TV receives the stream directly from the internet.
Connection problems and solutions
Despite the simplicity of the technology, users may encounter various difficulties when setting up the connection. One of the most common issues is when the phone simply doesn't see the TV in the list of available devices. In 90% of cases, this is resolved by rebooting the router, as accumulated errors in the routing table can block device detection within the local network.
Another common cause is the activated client isolation mode (AP Isolation) in your router settings. This security feature prevents devices connected to Wi-Fi from communicating with each other. If you have access to the router's admin panel, make sure this option is disabled. You should also try disabling the VPN on your smartphone, as the virtual tunnel can hide the device from the local network.
If the image is transmitted, but with significant lag or artifacts, the problem lies in an unstable signal. Try moving closer to the router or removing any physical obstructions. Bandwidth is critical for transmitting high-definition video (4K).
- 🔄 Restart your router, TV, and smartphone one by one.
- 📡 Check if Airplane mode or power saving mode is enabled on your phone.
- 🔒 Make sure your antivirus or firewall software on your smartphone isn't blocking local connections.
- 📶 Switch your router to a channel with less traffic (use Wi-Fi analyzers).
In some cases, resetting the network settings on your TV can help. Go to Settings → Network → Wi-Fi connection, select your network, and click "Delete" or "Forget." Then, re-enter the password. This will clear the network settings cache and often resolve Wi-Fi freezing issues.
Comparison of methods and selection of the optimal option
The choice of a specific connection method depends on your goals. If you need to share a photo gallery with friends or play a mobile game on a big screen, then the technology Miracast (Screen Share) will be the undisputed leader thanks to its minimal lag and complete interface duplication. However, this requires the phone to remain awake, which drains battery life.
For long-term viewing of movies or TV series from online cinemas, it is preferable to use the built-in Chromecast or broadcast via the app LG TV PlusThis frees up your smartphone and allows you to use it as a remote control without interrupting playback. Furthermore, the picture quality when directly uploaded to your TV is often superior to that of screen mirroring.
It's also worth considering your router model. Older 802.11n devices may not be able to handle high-definition video streaming when mirroring, causing image stuttering. Owners of such routers are advised to use a wired connection for their TV or upgrade their network equipment.
Why doesn't my LG TV see my phone when I try to connect?
Most often, the problem is that the devices are on different subnets or client isolation is enabled on the router. Also, check if your phone's antivirus software is blocking local device detection.
Is it possible to connect a phone to a TV without Wi-Fi?
A wireless connection by definition requires a Wi-Fi network (even without internet access, but with a working router). Without Wi-Fi, you can only use wired adapters (HDMI/MHL) or Wi-Fi Direct technology, if supported by specific models, which also uses a Wi-Fi module.
Does phone connection affect internet speed?
Using Google Cast (video streaming) places minimal strain on the network, as the stream is sent directly from the server to the TV. With screen mirroring (Miracast), the phone encodes the video and streams it to the TV, which creates additional strain on the local network but doesn't necessarily reduce internet speeds for other devices, provided the bandwidth is sufficient.
How to improve picture quality during broadcasting?
Use the 5 GHz band, close background apps on your smartphone that may consume data, and ensure the distance between the router and your devices is as short as possible. You can also select "Bright" or "Game" picture mode in your TV settings to reduce latency.
