If you're wondering how to connect your tablet to an LG TV via Wi-Fi, it's time to ditch the extra wires and enjoy the freedom of wireless technology. This isn't just convenient for sharing photos from a family dinner, it's also essential for playing videos from mobile apps that aren't supported by the built-in Smart TV.
The process of synchronizing devices depends on the version of your tablet's operating system and the year of manufacture. LG TVModern models support the standards Miracast And DLNA "Out of the box," while older versions may require additional software installation. In this article, we'll detail all the available options so you can choose the one that best suits your situation.
It is important to understand that for stable operation without delays, both devices must be on the same local network. Wi-Fi data transfer speed directly affects image quality, so for streaming 4K content, it is recommended to use a router that supports the 802.11ac standard or later. Let's take a look at what tools are offered by the TV manufacturer itself and by third-party developers.
Preparing equipment and network
Before you begin setting up, you need to make sure that the basic parameters are correct. Local area network The network must be configured so that devices can "see" each other. Users often make the mistake of connecting the TV to a guest Wi-Fi network or the 2.4 GHz band while the tablet operates on 5 GHz, which can create visibility issues with some router configurations.
Turn on yours Smart TV and go to the settings menu. Find the section responsible for network connection and ensure the connection status is active. If you're using a wired Ethernet connection for your TV, that's even better, as it will ensure a stable data stream while the tablet communicates with the router over the air.
- 📡 Make sure your router is distributing IP addresses via DHCP so that both devices receive addresses in the same subnet.
- 📱 Check the operating system version on your tablet - for Android, this is usually Android 5.0 or higher, for iOS, the current version.
- 🔌 Disable the "Guest Network" mode on your router if it is enabled, as it isolates devices from each other.
It's also worth updating your TV's software. Manufacturers regularly release patches that improve compatibility with new data transfer protocols.

Frequently Asked Questions (FAQ)
Why doesn't my LG TV see my tablet in the list of devices?
Most often, the problem is that the devices are connected to different networks (for example, one to 2.4 GHz, the other to 5 GHz, and the router is isolating them) or client isolation is enabled. Also, check whether your antivirus software is blocking the local connection.
Is it possible to connect a tablet to an LG TV without Wi-Fi?
Yes, you can use a cable connection. Modern tablets will require a USB-C to HDMI adapter. Older models with micro-USB will require MHL support. This will ensure the best quality and the absence of lag.
The sound is delayed when streaming via Wi-Fi. What should I do?
There's a lip-sync error when using Miracast. Try finding "Sound Sync" or "Audio Delay" in your TV settings and adjusting the value. Switching to DLNA also helps, if the file format allows it.
There's only a picture, but no sound. What's wrong?
This may be due to DRM restrictions in some apps (for example, Netflix or online movie theaters prohibit audio/video output through simple mirrors). Also, check the sound settings on your tablet—it may be set to output only to the device's speaker.
What is the maximum resolution supported by Wi-Fi streaming?
Miracast and AirPlay 2 theoretically support up to 4K at 60 Hz, but actual quality depends on the speed of your Wi-Fi router. For stable 4K playback, you need an AC1200 or higher router operating in the 5 GHz band.
