Modern technologies make it possible to transform a TV into a full-fledged multimedia center, streaming content from any mobile device. The question is, How to display a phone on a TV via Wi-Fi on an LG device, is becoming especially relevant for Smart TV owners who want to watch videos, photos, or play games on a larger screen. This eliminates the need for cables and allows for freedom of movement around the room.
Unlike wired connections, wireless technology Miracast The manufacturer's proprietary solutions don't require complex router settings. Simply connect both devices to the same local network, and the system will automatically detect available signal receivers. The synchronization process takes just seconds, after which the smartphone screen is fully mirrored on the TV.
It's important to note that image quality directly depends on your home network's bandwidth and the Wi-Fi standard. To stream 4K video, the resolution must be at least 3840×2160, and the refresh rate is 60 HzIn this article, we'll cover all available connection methods, from built-in features to third-party utilities.
Basic requirements and equipment preparation
Before you begin setting up, you need to make sure that your equipment meets the minimum technical requirements. Most modern models LG, released after 2014, are equipped with a wireless module and support the DLNA standard. However, for the Screen Share function to work fully, it is necessary to have support Miracast, which is built into the Android and Windows operating systems.
The key to stable operation is that the smartphone and TV are on the same subnet. If you have a dual-band router, make sure both devices are connected to the same frequency, for example, 2.4 GHz or 5 GHzMixing bands sometimes results in devices simply not seeing each other in the list of devices available for connection.
⚠️ Note: If your router is configured with AP Isolation, wireless connections between devices will be blocked at the hardware level. In this case, you must go to your router settings and disable this feature.
It's also worth checking the operating system version on your mobile device. For Android, versions higher than 4.2 are considered current, and for iOS, versions higher than iOS 12 are considered current. Outdated software may not support modern video compression codecs, which will result in delays or no video.
Using LG's built-in Screen Share feature

It's worth noting that when using this method, the phone may become slightly warm due to the active processing of the video stream. This is normal, but if the device overheats, it's best to stop broadcasting.
Stream from iPhone and iPad (AirPlay 2)
For equipment owners Apple I was luckier, since many modern TVs LG received technology support AirPlay 2This allows you to stream content directly through the standard "Screen Mirroring" menu without installing additional apps. The technology ensures minimal latency and high picture quality.
To get started, make sure AirPlay is enabled on your TV. To do this, go to Settings → Support → AirPlay SettingsMake sure the switch is in the "On" position. If this option isn't present, your TV model may require a firmware update.
⚠️ Note: The webOS menu interface may differ depending on your TV's operating system version. If you don't see the AirPlay option, check the "General" or "Network" section.
On your iPhone, open Control Center (swipe down from the top right corner or up from the bottom on older models). Tap the two rectangles icon (Screen Mirroring) and select your LG TVA code may appear on the TV screen that you need to enter on your smartphone for pairing.

|---|---|---|---|
| Screen Share (Miracast) | Android, Windows | High (up to 1080p) | Low |
| AirPlay 2 | iOS, macOS | Very High (4K HDR) | Minimum |
| LG TV Plus | Android, iOS | Average | Average |
| Google Home | Android, iOS | High | Low |
Solution: The TV doesn't detect the phone.
The most common issue is that the device isn't listed as available. This can be caused by firewall settings on your router or antivirus software. Check if the network profile is set to "Private Network" instead of "Public Network," as the latter blocks detection.
Another reason is outdated software. Go to Settings → All settings → Support → Software update on your TV and check for new versions. Manufacturers regularly release patches that fix communication protocol errors.

Optimizing quality and eliminating delays
A stable connection is crucial for viewing dynamic content or gaming. If the image flickers or disintegrates into artifacts, it means there isn't enough bandwidth. In this case, The ideal solution would be to use a router that supports the Wi-Fi 5 (802.11ac) or Wi-Fi 6 standard., operating in the 5 GHz range.
The 2.4 GHz band is often congested with neighboring routers and household appliances, causing interference. Switching to 5 GHz significantly frees up airspace. However, keep in mind that high-frequency signals have poorer penetration through walls, so the distance between the router and TV shouldn't be too great.
It's also worth closing background apps on your smartphone that may consume bandwidth (cloud syncs, downloads). This will free up processor resources and bandwidth for transmitting the live video stream.
Alternative methods and third-party software
When standard methods fail, universal solutions come to the rescue. Appendix AllCast or LocalCast Allows you to stream video directly from the player, bypassing the system's screen sharing. This reduces the load on your phone's battery.
Advanced users can set up a DLNA server on their computer and stream content through it to their TV, using their phone as a remote control. This is a more complex but flexible way to organize your media library.
Some users prefer to use Wi-Fi-enabled HDMI adapters, such as Chromecast or Miracast dongles, if the TV's built-in module is unstable. This external device takes over the stream decoding task, reducing the system load. LG.
Is it possible to display the screen on an old LG TV without Smart TV?
Yes, you'll need to purchase an external Android TV box or a special Miracast adapter that plugs into the HDMI port. An older TV without a Wi-Fi module won't be able to stream on its own.
Why is there no sound during the broadcast?
Most often, the problem lies with the audio codec format, which isn't supported by the TV when streaming wirelessly. Try changing the audio settings in the source app or using a cable connection to test.
Does broadcasting affect internet speed?
Yes, because the video stream takes up a significant portion of the bandwidth. If you watch 4K video from your phone on a TV, other devices on the network may experience limited speed.
