You don't need to buy additional cables or adapters if both devices support wireless communication. In this article, we'll cover all the setup details, potential issues, and solutions for the highest quality image transfer.
The main advantage of this method is the speed of data transfer and lack of dependence on external infrastructure.

Unlike a classic home network connection, a separate communication channel is created here. This means that even if your home internet is down, photo streaming will work reliably. The encryption protocol WPA2 ensures that your personal photos will not be accessible to strangers within the signal range.
It's important to understand that for this feature to work, both devices must have working Wi-Fi modules. On the TV LG This process is controlled by a built-in controller, which automatically switches the antenna operating modes when the screen sharing function is activated.
It's worth noting that data transfer speeds may vary depending on the version of the Wi-Fi module in your phone. Modern standards Wi-Fi 5 And Wi-Fi 6 provide instant loading of large RAW files, while older standards may require more time to buffer.

☑️ Checking connection readiness
If you plan to transfer large amounts of data, free up your smartphone's RAM. Closing unnecessary apps will prevent lag and freezing when previewing images on the big screen.
Activating Screen Share on an LG TV
The first step is to put the TV into connection standby mode. On the remote control, press the button Input or select the appropriate item in the signal sources menu. In the list of available options, you need to find Screen Share (on older models it may be called Smart Share).
After selecting the option, a window will appear on the screen with your TV's name and standby status. This name will be displayed in the list of available networks on your smartphone. In some versions webOS You may be asked to confirm the connection from the remote control when the device is found.
For users who prefer the application menu, the built-in application can be launched Device Connector or similar, depending on the region and model year. It will automatically launch the required detection service.
What should I do if the Screen Share app won't launch?
If the built-in app isn't responding, try resetting your network settings. Go to Network → Wi-Fi Connection → Advanced Wi-Fi Settings → Edit → Reset. This won't delete your accounts, but it will refresh your network configurations.

Once the search starts, your phone will begin scanning the airwaves. Select your TV from the list of available devices. LGIf this is the first time you've established a connection, a permissions request will appear on the TV screen. This request must be confirmed using the button on the remote control.
An alternative method is to use an app LGTV Remote or Google HomeThese programs offer more advanced functionality, allowing you not only to mirror your screen but also to transfer files from your gallery directly to your TV's media player, which often provides better picture quality.
| Connection method | Advantages | Flaws | Quality |
|---|---|---|---|
| Screen Mirroring | Duplicates everything from the phone | High battery consumption | Depends on the phone |
| LG ThinQ app | Remote control, photo | Software installation required | Original |
| Google Home | Stability, ecosystem | Requires a Google account | High |
| AllShare (Samsung) | Transfer files without mirroring | Only for Samsung | Maximum |
When using third-party applications from Google Play, make sure you've granted the app permission to access your local network and location. Without these permissions, Android may block the app from searching for devices on the Wi-Fi Direct network.
Setting up broadcasting for iPhone (iOS) owners
Ecosystem users Apple can take advantage of the technology AirPlay, if their LG TV supports this feature (2019 models and newer with webOS 4.0+). First, make sure AirPlay is enabled in your TV settings: go to Settings → Connection → AirPlay and activate the switch.

Enter it on your smartphone screen to confirm pairing. If you set up automatic trust, you can skip this step.
AirPlay streaming quality is generally higher than that of third-party emulators, as it is Apple's native protocol, optimized for working with graphics and photos without heavy compression.
Using the LG ThinQ app
The most stable and functional way to view photos is to use the official application. LG ThinQIt's available for both platforms and provides deep integration with your TV. After installation and account registration, add your TV to the list of devices.
In the app interface, select your TV and find the media streaming option. You can select specific photos from your gallery and send them to the screen. The advantage of this method is that the TV decodes the image itself, offloading the load from the phone's processor.
The app also lets you create slideshows with music played through your TV's sound system. This transforms simple photo viewing into a full-fledged presentation or party atmosphere.
You can adjust the quality of transferred images in the app settings. For archived photos, it's best to select maximum quality, while for quickly scrolling through your social media feed, use data-saving mode, if available in your software version.
Solutions to common problems and errors
Users often encounter a situation where the TV simply "doesn't detect" the phone. In 90% of cases, the problem is that the phone has mobile data enabled, and the system prioritizes it, ignoring the local Wi-Fi Direct connection. Try temporarily disabling mobile data.
Another common issue is time desynchronization or an overflowing DNS cache. Restarting the router (if used for the initial handshake) and the TV itself by completely disconnecting it from the network for 10 seconds often resolves the issue.
If the image is transmitted, but with a delay or artifacts, try lowering the resolution of the transmitted photos or moving the phone closer to the TV. Walls and metal structures can block the 5 GHz signal, which is used to transmit heavy content.
⚠️ Note: Menu interfaces and item names may vary depending on the webOS version and regional firmware. If you don't find an exact match, look for synonyms or similar icons.If you experience persistent issues, check if your router is in AP Isolation mode. Although Wi-Fi Direct works directly, some router security settings may conflict with the TV's wireless module.
Why do photos on TV look stretched?
This happens because the aspect ratio of your phone's screen (often 19:9 or 20:9) and your TV's (16:9) don't match. In your TV's settings, press the
P: Ratioon the remote control and select the "Original", "Scan Only" or "4:3" mode to remove the edge cropping.Is it possible to transfer photos via Wi-Fi Direct without the Internet?
Yes, this is possible. Wi-Fi Direct creates a local network between devices. However, if the app requires internet access to authorize (for example, signing in to a Google or LG account), the initial setup may fail without internet access.
Does the TV take photos from the phone's cloud?
When using the Screen Mirroring feature, the TV displays what the phone's camera sees, including cloud photos uploaded to the gallery. Direct file transfer via DLNA/ThinQ only transfers files physically stored on the device.
How to improve the quality of colors during transmission?
In your TV's picture settings, select "Vivid" or "Standard." Also, disable "Auto-Brightness" and "Eye Care" in your phone's menu to ensure the colors on your TV match the actual file's colors.
Does my old LG support Wi-Fi Direct?
Almost all LG Smart TVs released after 2013 support this technology. If you have a model in the LB, LF, UF series or newer (e.g., 43UH603V, 49SM8200), the feature is guaranteed to be present in the Network or Screen Share menu.
