How to connect Xiaomi Redmi to LG TV: a step-by-step guide

Modern Xiaomi Redmi smartphones have powerful screens, but they are often not enough to watch content on a large diagonal. LG owners often face the need to stream photos, videos or games to a TV to get a more immersive experience. Fortunately, the Android ecosystem and webOS (LG TV Operating System) offer many compatible protocols for wireless and wired connections.

In this guide, we will take a look at all the available device synchronization methods, learn how to use the built-in Mi Drop and Mi Remote features, and set up a wired connection via HDMI for low latency gaming, and eliminate unnecessary theory and focus on practical steps that are guaranteed to work.

It doesn't matter if you have an old LG Smart TV or the latest 4K HDR panel, the algorithms will be similar, differing only in the menu names, and the main thing is to make sure that both devices are functional and ready to go.

Device preparation and network verification

Before setting up, you need to do basic training, and make sure your Xiaomi Redmi and LG TV are connected to the same Wi-Fi network, a critical condition for most wireless protocols like Miracast and DLNA to work.

Check the version of the operating system on your smartphone. Android 8.0 or higher is recommended for the broadcast functions to work correctly. On your TV, it is also advisable to update webOS firmware to the latest available version through the settings menu.

If you plan to use a wired connection, purchase a quality Type-C to HDMI adapter in advance. Cheap cables may not support video transmission, limited to just charging the device.

⚠️ Note: When using public Wi-Fi networks (in hotels or cafes), wireless broadcasting may not work due to port blocking by the network administrator.

Wireless connection via the Translation function (Miracast)

The most popular method is to use Miracast technology, which is built into the MIUI shell (HyperOS), which allows you to duplicate the screen of your smartphone on your TV in real time without the delays that you can see.

To start, open the control panel on your Xiaomi Redmi by swiping from top to bottom. Find the Broadcast (or Cast) icon. If the icon is not available quickly, go to Settings β†’ Connection and Sharing β†’ Broadcast.

Turn on the feature and wait for the available devices. On the LG TV remote, click Input or Smart and select the Screen Share app (in new models it may be called Connection Guide). Once the TV appears on the list on your smartphone, click on it to pair.

  • πŸ”— Wait for the phone name to appear in the list and confirm the connection.
  • βœ… Image from the phone is duplicated on the entire screen of the TV.

It is worth noting that when you are actively using your phone during the broadcast, notifications will come to the big screen, and to avoid embarrassing situations, turn on Do Not Disturb mode before you start watching.

Use of the built-in LG TV Plus app

The official app from the TV maker often works more stable than standard Android tools. The LG TV Plus app (formerly known as LG Remote) allows you not only to control the TV, but also to transfer media files.

Download the app from the Google Play Store to your Xiaomi Redmi. Run the program and allow access to the local network. The app will automatically start searching for TVs on the Wi-Fi network.

Once you select your LG Smart TV, you'll see a confirmation code on your TV screen, enter it on your smartphone or click "Accept" on the remote, and you can now use your phone as a remote and stream photos and videos from the gallery.

⚠️ Note: Full screen duplication in this application may be limited, and is primarily intended for media content (photos, videos, music) and not for games.

To transfer files, open the gallery in the app, select the photo or video you want, and click the Cast button (the Wave rectangle icon). The content will open on the TV, allowing you to continue using your smartphone for other tasks.

Broadcasting through YouTube and streaming services

If you want to watch videos from YouTube, Netflix or other services, it's not effective to use full screen duplication, and it's easier and better to use the built-in Google Cast feature.

Open the YouTube app on Xiaomi Redmi. In the upper right corner of the video or in the app interface, find the Translate icon (a rectangle with Wi-Fi waves).

In the list of available devices, select your LG Smart TV. The video will run directly through the TV’s Internet channel, which will ensure maximum picture quality (up to 4K) and save battery life.

Why can video slow down when broadcasting?
If you use full screen duplication (Miracast), the phone encodes the video stream and sends it to the TV, which loads the processor. When you use the Translate button inside the YouTube app, the phone acts as a remote, and the video is downloaded by the TV itself directly from the network, which is much more efficient.

Connecting via HDMI adapter

For gamers or users who want maximum stability and no delays, a wired connection is ideal. You will need a USB Type-C to HDMI adapter.

Connect the adapter to the Xiaomi Redmi charging connector, and then connect it with an HDMI cable to an LG TV. Switch the signal source on the TV to the appropriate port (for example, HDMI 1).

The smartphone automatically detects the external connection and displays the image. In the phone settings (Settings β†’ Connection and Sharing β†’ Connecting to HDMI), you can choose the mode of operation: mirror display or extended desktop (if supported).

Set up TV control via Mi Remote

Xiaomi smartphones have a unique feature – built-in infrared port (on most models of Redmi Note and flagships), which allows you to use the phone as a universal remote even without connecting to Wi-Fi.

Find the Mi Remote app in the Tools folder. Run it and click Add Remote. From the manufacturer list, select LG.

Follow the instructions on the screen: the phone will send signals, and you need to confirm whether the TV is responding. After successful testing of all the buttons, you will be able to fully control the volume, channel and signal source, even if the TV is turned off (Wake-on-IR function).

πŸ’‘

If your Redmi doesn’t have an IR port (like the Redmi 12C or some global versions), Mi Remote won’t be able to control the TV directly, in which case use Wi-Fi control mode in the same app, but the TV and phone must be on the same network.

Troubleshooting and troubleshooting

Often, users are faced with a situation where the phone can not see the TV. 90% of the time the problem lies in the Wi-Fi frequency range. Make sure that both devices are connected to the same frequency: either both at 2.4 GHz or both at 5 GHz.

If the image is twitching or low resolution, try to reduce the load on the network. Turn off downloads on other devices or move the router closer to the TV. For wired connection, use HDMI 2.0 and higher cables to support 4K.

In rare cases, resetting your network settings on your smartphone helps. Go to Settings β†’ Connection and Sharing β†’ Reset Wi-Fi, mobile networks and Bluetooth. This will not delete your personal data, but will return your network settings to factory settings.

⚠️ Note: Antivirus apps or β€œoptimizers” on Xiaomi can block local connection. Add the broadcast app to the exceptions or auto-run list.

πŸ’‘

The most common cause of problems is different Wi-Fi subnets (guest network or 2.4/5 GHz partition) and make sure that devices see each other on the LAN.

Why does the phone connect but write β€œPlug-in error”?
This can be due to a crowded TV clipboard or an outdated security certificate. Try rebooting both devices. If it doesn't work, remove the phone from the list of allowed devices in the TV menu (Settings β†’ Connections β†’ Device List) and try re-cooking it.
Can I output the sound to external speakers through a connected phone?
When using Miracast, the default audio goes through the TV. To change this, during the broadcast, click on the audio icon on the phone and select the desired output device if the system allows for the separation of audio streams. In wired mode, sound is always transmitted along with the video.
Does my Redmi support image output over cable?
The DisplayPort Alt Mode is mainly based on the flagship series (Mi 9, Mi 10, Mi 11 and above) and some Redmi K-series models (globally called Xiaomi). Budget Redmi (Note 8, 9, 10, 11, 12 in the base versions) are most often devoid of this feature hardware.
How to improve the quality of the picture in wireless broadcasting?
Xiaomi's Translation menu often has resolution settings. Try setting 1080p 60fps if your router supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX) standard. Also close the background apps on your phone to free up CPU resources for encoding video.
