If your LG TV is not appearing on screen mirroring, the most common cause is that your TV and device are not connected to the same Wi-Fi network. Ensuring both devices share the exact same network is essential for the TV to show up as an available option for screen mirroring.
Without this, your device won’t detect the LG TV, preventing the connection. Other factors such as outdated software, incorrect input modes, or temporary glitches can also interfere with screen mirroring.
By checking these settings and updating your devices, you can often resolve the issue quickly and get your content displaying properly.
Understanding Why LG TV Is Not Appearing on Screen Mirroring
You need to ensure your LG Smart TV is properly set up and your casting device meets specific requirements. A stable and correctly configured Wi-Fi network is essential for establishing a wireless connection between your devices.
How Screen Mirroring Works on LG TV
Screen mirroring on an LG TV relies primarily on technologies like Miracast for most Android and Windows devices, and AirPlay or AirPlay 2 for Apple devices. These protocols create a direct wireless display link, allowing your casting device to stream content or duplicate the screen on your TV.
LG Smart TVs often label this feature as Screen Share, which needs to be selected as the TV’s active input mode to receive mirrored content. If your TV remains on HDMI or another input mode, it won’t appear as available for screen mirroring.
Screen sharing requires your TV’s firmware to be up to date, as outdated firmware can lack support for the latest mirroring protocols or have bugs causing connection failures.
Device Compatibility Requirements
For successful screen mirroring, both your LG TV and casting device must support compatible standards. Your LG TV generally needs to have Miracast built in if you use Windows or Android devices.
For Apple iPhones or iPads, AirPlay 2 support is necessary. Not all devices on your network may be compatible.
The casting device should also run software versions that support wireless display or have screen cast features enabled, like Smart View on Samsung phones or Wireless Display on Windows PCs. Trying to cast from incompatible devices or applications, especially those with DRM (digital rights management) protection, can cause your LG TV not to appear in the screen mirroring list.
Network Connection Essentials
Your LG Smart TV and casting device must be connected to the same Wi-Fi network for screen mirroring to work. This means both should be linked either to the same 2.4GHz or 5GHz band within your home network.
Discrepancies here are a common reason your TV won’t show up as a casting option. If network interference is suspected, using a wired connection like Ethernet for the TV can improve stability.
Having multiple casting devices connected simultaneously or Bluetooth devices operating on the 2.4GHz band may interfere with the connection. Ensure that your network settings don’t block communication between devices, such as firewalls or privacy settings on your casting device that might prevent proper discovery of your LG TV for screen sharing.

Common Causes for LG TV Not Showing Up in Screen Mirroring
When your LG TV fails to appear as an option for screen mirroring, several technical factors could be at play. Typically, issues arise from settings on your TV, problems with your network, outdated software, or hardware interference.
Disabled Screen Mirroring Settings
One of the most frequent reasons your LG TV won’t show up as a screen mirroring option is that the feature is disabled or not activated on the TV. Screen mirroring must be explicitly enabled in your TV settings under Inputs or Screen Share.
If your TV’s input mode is set to HDMI or another source rather than Screen Share, your casting device won’t detect it. Ensure you navigate to the TV’s Settings → Inputs → Screen Share and activate it.
Sometimes, the TV might require you to restart it or reconnect the paired device after enabling this feature. Forgetting to change or enable the mirroring mode is one of the easiest mistakes to make and often the quickest fix to implement.
Network Issues and Wi-Fi Signal Problems
Screen mirroring depends heavily on your TV and casting device being connected to the same stable Wi-Fi network. If your TV is connected to a different Wi-Fi band (2.4GHz vs 5GHz) or a different network altogether, it won’t show up as a casting option.
Network congestion can also degrade the connection, causing the TV to disappear during mirroring attempts. Weak Wi-Fi signals, especially if your LG TV is located far from the router, can disrupt the connection.
Using an Ethernet cable connection to your TV can improve reliability in some cases. You should also verify that no VPNs or network firewalls are blocking the devices from communicating.
Outdated Software or Firmware
Your LG TV’s software needs to be up to date to support modern screen mirroring protocols like Miracast, AirPlay 2, or Wi-Fi Direct. If your TV firmware is outdated, incompatibilities may cause the TV not to be recognized during casting attempts.
Check for software updates regularly through Settings → Support → Software Update. Updates often include critical bug fixes and improvements that address connectivity and compatibility issues with newer devices.
Hardware Malfunctions and Interference
Physical hardware problems or external interference can block your LG TV from appearing in screen mirroring options. Internal Wi-Fi modules might malfunction or lose connection ability, especially if the TV passes through power surges or prolonged usage.
Bluetooth devices operating on the same 2.4GHz band as your Wi-Fi can introduce interference, disrupting the signal. Temporarily turning off nearby Bluetooth gadgets and switching your Wi-Fi to a 5GHz band, if supported, can reduce this conflict.
Additionally, any faulty cables or ports connected to the TV can affect mirroring capabilities indirectly through system performance issues.
Step-by-Step Solutions to Fix Screen Mirroring Issues
Troubleshooting LG TV screen mirroring involves checking device compatibility, network settings, and TV configuration. You also need to ensure your TV’s software is current and restart devices when necessary.
Verifying Device and TV Compatibility
Before attempting screen mirroring, confirm that both your TV and the device you want to mirror from support the same technology. LG TVs typically support AirPlay for Apple devices, Miracast for many Windows and Android devices, and DLNA for media sharing.
Check your device’s specifications or user manual to ensure it supports screen casting features. Some older devices or non-smart TVs may not be compatible.
If you plan to use HDMI cables, verify the cable is in good condition since damaged cables can cause disconnections and no display. If your device uses Chromecast, note that LG TVs do not natively support Chromecast mirroring but may allow casting through apps.
Confirming compatibility prevents wasted time troubleshooting issues that result from unsupported connections.
Connecting to the Same Wi-Fi Network
Both your LG TV and your mirroring device must be connected to the exact same Wi-Fi network to enable seamless screen sharing. A mismatch in networks or unstable connectivity can cause the TV not to appear in the device’s screen mirroring list.
Double-check you are not connected to guest networks or different bands (2.4GHz vs. 5GHz) if your devices are incompatible across frequencies. Use a speed test to confirm your network’s stability.
If you’re using a wired LAN connection for your TV, ensure cables are correctly plugged in and functioning. Avoid running heavy internet tasks that may affect bandwidth during mirroring.
