Understanding the principles of protocol operation Miracast And DLNA will help you avoid common connection errors.
Preparing equipment and network
The first and most critical step is ensuring the correct network environment. For successful data transfer, both devices—the mobile device and the LG Smart TV — were on the same local network. This means that they must be connected to the same router via WiFi.
A common mistake users make is using different router frequency bands without proper configuration. If your router broadcasts 2.4 GHz and 5 GHz networks with different names, make sure both devices are connected to the same band. Ideally, it's better to use the 2.4 GHz and 5 GHz bands for heavy video streaming. 5 GHz, which provides higher throughput.
⚠️ Note: If you use a guest WiFi network or client isolation on your router, devices may not be able to see each other even if they are on the same network.
It's also worth checking that the software is up to date. On TVs LG with the operating system webOS Updates are released regularly to improve the stability of wireless modules. Before starting setup, we recommend going to the update menu and installing the latest available firmware version.

Why might the app not see TV?
If your LG ThinQ TV isn't detected, check the app permissions. It requires local network access to function properly (especially relevant for iOS 14+ and Android 10+). Also, make sure AP isolation isn't enabled on your router.

Solution and optimization
Even with proper setup, technical difficulties may arise. The most common issue is that the TV isn't visible in the list of available devices. In this case, try rebooting the router, as the module WiFi may freeze or get an IP addressing error.
If the image is choppy or the video is constantly buffering, the problem lies with your wireless connection speed. Try moving closer to the router or clearing the WiFi channel from neighboring networks. Bandwidth usage 5 GHz significantly reduces the likelihood of interference.

Frequently Asked Questions (FAQ)
Is it possible to mirror iPhone screen to LG without WiFi?
Without a WiFi network, direct streaming via AirPlay is impossible, as the protocol requires a local network for data transfer. However, some LG models support Wi-Fi Direct, which creates a direct connection between the phone and TV, but AirPlay 2 still requires a router.
Why is there no sound on the TV during broadcasting?
Check the audio output settings in the app you're streaming from. Sometimes the audio remains on your phone. Also, make sure your TV isn't in "Picture Only" mode (if the specific app you're streaming from has this option).
Does broadcasting affect internet speed?
Yes, streaming high-definition video (4K) consumes a significant amount of bandwidth. If someone else on the network starts downloading large files or playing online games, the picture quality on your TV may degrade.
Do older LG TVs support these features?
Older models (before 2014-2015) may not have built-in Miracast or AirPlay 2 support. In this case, wireless streaming will require connecting an external set-top box, such as a Chromecast or Apple TV.
