Modern multimedia capabilities allow you to turn any smartphone into a powerful remote control and content source for the big screen. Owners of the bundle Xiaomi And LG People often look for ways to stream videos, photos, or games to their TV wirelessly. This is convenient for watching movies in high definition or sharing presentations with colleagues.
Wireless connection technology is based on the Wi-Fi Direct and DLNA standards, which are built into the operating systems of both devices. However, despite the widespread use of these protocols, the setup process may have its own nuances depending on the version. firmware and router model. Proper network configuration will ensure smooth data transfer without delays.
In this article, we'll cover all available sync methods, from built-in system features to third-party apps. You'll learn how to activate Miracast, setting up AirPlay 2, and which router settings affect image quality. A thorough understanding of these processes will help you avoid common connection errors.
Network requirements and equipment preparation
The first and most important condition for successful synchronization is that both devices are on the same local network. This means that both the smartphone and TV must be connected to the same router. If you have a dual-band router, make sure both devices are using the same frequency, such as 2.4 GHz or 5 GHz, although modern routers can automatically combine clients.
Connection stability directly depends on signal quality. Wi-FiStreaming 4K or HDR video requires high bandwidth. A weak signal can result in image artifacts or even complete connection loss during playback.
It's also worth checking the software of your devices. On your TV LG with the system WebOS and on a smartphone Xiaomi with shell MIUI The latest available updates must be installed. Manufacturers often fix detection protocol bugs in security patches.
⚠️ Important: If your router has a "Guest Network" feature, make sure client isolation is not enabled. In this mode, devices cannot see each other and connection will be impossible.
You can use built-in diagnostic tools to check signal quality. On Android, this is available in a hidden menu or through third-party utilities. On a TV, signal strength information is available in the network settings.
Using the built-in Screen Share (Miracast) feature
The most versatile way to mirror your screen is to use technology MiracastOn TV LG This function is often called Screen Share or Connecting to a phoneSmartphones Xiaomi support this protocol natively, without requiring the installation of additional software.

This method is great because it mirrors absolutely everything that's happening on your phone's screen. However, keep in mind that if you're actively using your smartphone, the TV image may be interrupted by notifications or calls.
Why might the broadcast be slow?
Lag is often caused by Wi-Fi congestion. If neighbors are using the same frequencies, or if large files are downloading in the background, the bandwidth may not be sufficient for a high-definition video stream.
Streaming via Google Home and Chromecast
Most modern televisions LG have built-in support for the technology Chromecast built-inThis allows you to stream content from apps directly without overloading your smartphone's processor. The official app is used to manage this process. Google Home.
First, make sure the app is Google Home installed on your XiaomiOnce launched, the app will automatically find your TV on the network. Tap the device icon to access controls.
