Wi-FiThe router acts as an intermediary, transmitting a digital stream of video signals or static images from the source to the receiver. Data transfer speed directly depends on the bandwidth of your wireless router and the distance to it.
In this article, we will examine in detail all the current connection methods, starting from the built-in functions of the operating system itself. LG webOS and ending with third-party applications. You will learn how to set up DLNA, use the function AirPlay 2 for iPhone owners or use the standard protocol MiracastWe'll also cover image quality and potential file format compatibility issues.

Settings → Network → Wi-Fi connectionIf the TV is connected via a LAN cable and the phone via Wi-Fi, this will also work in most cases, as the devices will be on the same router subnet.
Pay attention to the signal frequency. For transmitting high-resolution photos (especially RAW or 4K), it is preferable to use the range 5 GHz, which provides higher data transfer rates than 2.4 GHz. However, it has a shorter range, so the router must be located close to the receiver.
⚠️ Note: If your router is broadcasting two networks with the same name (Dual Band), try temporarily separating them into different SSIDs (e.g., Home_2.4 and Home_5G) and connect both devices to only one of them. This will prevent routing conflicts.
It's also worth checking if the device discovery feature is enabled. On TVs LG the service is responsible for this LG Connect Apps or similar system services that are enabled by default but can be disabled in privacy settings. Without this, the phone simply won't "see" the TV in the list of available devices.
Using the built-in Smart Share (DLNA) feature
The most universal and time-tested method is the use of technology DLNA (Digital Living Network Alliance). In the ecosystem LG This function is often called Smart ShareIt is built directly into the TV's operating system and does not require the installation of additional applications on the TV.

Frequently Asked Questions (FAQ)
Is it possible to transfer photos if there is no internet, but there is a Wi-Fi router?
Yes, you can. DLNA, Miracast, or AirPlay don't require internet access. Simply having the router create a local area network (Local Area Network) is sufficient. Even without a provider cable connected to the WAN port, devices will be able to see each other via the router's Wi-Fi module.
Why doesn't my LG TV see my phone in the list of devices?
The most likely cause is that the devices are connected to different networks (for example, one to a guest Wi-Fi network and the other to the main network). Also, check whether AP Isolation mode is enabled on the router and whether the phone app has access to the local network in the OS privacy settings.
Does my old LG TV support AirPlay?
Native AirPlay 2 support is available on LG TVs running webOS 4.0 and higher (2018-2019 models and newer). If you have an older model, you'll need to use third-party receiver apps installed on the TV itself via the LG Content Store, such as: AirScreen or TV Assist.
Does transferring photos affect the quality of the original file?
When using DLNA and AirPlay 2, the original file is transmitted uncompressed, so the quality remains identical. When using screen mirroring (Miracast/Screen Share), the image is compressed into the video stream, which may result in a slight loss of detail, noticeable only at close zoom levels.
