What if my TV isn't on Google Home?
Make sure the Google account on your TV and phone is the same, or that the devices are on the same network. Try restarting your router. In some regions, this feature may need to be activated in the LG Content Store settings.
Connecting iPhone and iPad via AirPlay 2
For equipment owners Apple luckiest of all: modern televisions LG support the protocol AirPlay 2 "Out of the box." This means you don't need to install any additional apps to display photos, videos, or the entire screen. The system works natively and ensures the highest connection stability.
To start casting, open Control Center on your iPhone (swipe down from the top-right corner or from the bottom up, depending on your model). Tap the "Screen Mirroring" button and select your TV.

If you are using older iPhone or iPad models that do not support AirPlay 2, you can use third-party apps from App Store, such as TV Cast or ReplicaThey emulate the protocol but may introduce a slight delay in image transmission. For viewing photos and presentations, this is a perfectly acceptable solution.
Third-party apps for advanced features
The built-in tools don't always cover all user needs, especially if you need to play a file of a specific format. LG Content Store Or on mobile platforms, you can find utilities that expand functionality. Popular solutions include TV Cast, AllConnect And BubbleUPnP.
Application TV Cast Allows you to send video files to your TV that are not supported by the built-in player, as well as broadcast browser tabs.

Troubleshooting connection and buffering issues
Even with a perfect setup, there may be situations where video drops or the device isn't visible on the network. Most often, the problem stems from radio channel congestion from neighboring routers. In this case, switching to a less congested frequency or channel in the router settings helps.
If the stream keeps cutting out in the middle, try lowering the video quality in the source app settings. Streaming to 1080p requires less than 4K, and is more resistant to interference. It's also worth checking that your phone isn't running background downloads that are consuming all your bandwidth.
⚠️ Please note: The menu interface on LG TVs may differ depending on the version of the webOS operating system (3.0, 4.0, 5.0, 6.0, and later). The location of settings items may be changed by manufacturers through software updates.
If there's no image at all, check the date and time on both devices. System clocks out of sync for more than 5 minutes can cause security certificate errors, causing content protection protocols to block the connection. Setting the time correctly often resolves the "black screen" issue with sound.
Optimizing wireless network quality
For those seeking cinematic quality wirelessly, not only speed but also ping stability are important. Placing the router in a visible location, away from microwaves and metal structures, significantly improves the signal. Bandwidth Utilization 5 GHz It is preferable for video transmission because it is less noisy.
If the distance between the router and TV is large, you can use Wi-Fi repeaters or mesh systems to extend the coverage. However, for streaming, it's best for the TV and phone to connect to the same base station. Switching between access points while watching may cause connection interruptions.

Most often, the devices are on different networks (for example, a guest network for a phone and the main network for a TV). Network discovery may also be disabled in the router settings (AP Isolation). Make sure Bluetooth is enabled on both devices, as it is often used for initial pairing.
Is it possible to play games on a phone and output them to a TV?
Yes, via Screen Share (Miracast). However, input lag can range from 100 to 300 ms, which is critical for fast-paced shooters. For more sedate strategy games or trivia games, this method is perfectly suitable. For games with minimal latency, a wired HDMI connection is better.
Is the sound transmitted to external speakers when a phone is connected?
When using AirPlay 2 and Chromecast, audio is transmitted separately and can be output to a connected audio system or soundbar. When using screen mirroring (Miracast), audio typically comes through the TV speaker, but some phone models allow you to redirect the audio stream to a Bluetooth headset.
