Quick answer
To screen mirror to an LG TV, first identify both the source device and the feature supported by the exact television model. Use AirPlay for a compatible iPhone, iPad, or Mac; Screen Share/Miracast for a compatible Android phone or Windows PC; or Google Cast only when the LG Home Hub or receiving app shows Cast support. Connect both devices to the same Wi-Fi network when the selected method requires it, choose the LG TV, and accept the connection or enter the code shown on the television.
If the television does not appear, do not install a random “mirroring” APK or disable router security. Confirm the model’s user guide, update both devices, enable the correct receiving feature, and test with an ordinary photo or home screen. HDMI is the reliable fallback when the TV or source device lacks a compatible wireless standard.
Choose mirroring, casting, or HDMI
These terms are often mixed together, but they describe different paths. Mirroring duplicates the source device’s screen. Casting sends supported media to a receiving app or built-in Cast target while the phone acts as a controller. HDMI carries a wired video and audio signal. The best route is the one supported by both endpoints, not the one with the most familiar logo.
| Source device | Best first route | What must be supported |
|---|---|---|
| iPhone or iPad | AirPlay / Screen Mirroring | AirPlay-compatible LG TV and same Wi-Fi network |
| Mac | AirPlay from Control Center | AirPlay-compatible LG TV and same Wi-Fi network |
| Android phone or tablet | Screen Share / Smart View / Cast, depending on device | A matching receiver on the LG TV; menu names vary by phone |
| Windows 11 PC | Windows + K wireless display | Miracast support on both the PC and LG TV |
| Any compatible computer or phone | HDMI adapter or cable | Correct source-device video output, adapter, cable, and TV input |
Check your LG TV before connecting
- Find the model and webOS version. Open the TV’s Support, About This TV, or TV Information screen. Menu wording varies by model year.
- Check the user guide. Look for AirPlay, Screen Share, Miracast, Google Cast, Home Hub, or wireless display. Do not assume every LG TV supports every method.
- Update the television. Install the supported webOS firmware and restart once. If you also need app-update steps, use How to Update Apps on a Smart TV.
- Check the network. Put the TV and source device on the same normal home network. Guest networks and client-isolation settings can prevent device discovery.
- Rename duplicate TVs. If several LG displays appear, give the intended television a recognizable device name before accepting a connection.
LG says feature availability and ports vary by product model. Its support instructions are designed for multiple models, so the pictures and exact menu path may not match every TV.
Mirror an iPhone or iPad to an LG TV
LG directs compatible iPhone users to AirPlay. Apple’s current instructions require the iPhone or iPad and the AirPlay-compatible smart TV to be on the same Wi-Fi network.
- Turn on the LG TV and confirm AirPlay is enabled in its AirPlay and HomeKit settings.
- Connect the iPhone or iPad to the same Wi-Fi network as the TV.
- Open Control Center.
- Tap Screen Mirroring.
- Select the LG TV from the displayed devices.
- If the TV shows an AirPlay code, enter that code on the Apple device.
- To stop, return to Screen Mirroring and choose Stop Mirroring.
LG’s current support page says AirPlay is available on supported models and notes support from 2018 webOS 4.0 products onward, but model, region, firmware, and feature availability still need to be checked. A television purchased earlier—or a later model sold in a different market—should be verified by model number rather than by year alone.
Stream a video instead of mirroring the whole iPhone
If an app includes an AirPlay button, use it when you only want to send that app’s supported video or photos. Open the content, tap the AirPlay control, and choose the LG TV. This can leave the phone available for other tasks and may work differently from duplicating the whole screen.
An app can set its own playback, account, rights, and output restrictions. AirPlay does not grant access to a title or override a service’s rules. If a supported streaming app refuses screen mirroring, use the service’s official LG app or its documented AirPlay route rather than attempting to bypass the restriction.
Mirror a Mac to an LG TV
- Connect the Mac and compatible LG TV to the same Wi-Fi network.
- Open Control Center on the Mac.
- Select Screen Mirroring.
- Choose the LG TV.
- Enter the code displayed on the TV if requested.
- Use macOS display settings to choose mirror or extended-display behavior where supported.
If the TV is missing, confirm AirPlay is enabled, update both devices, move them closer to the router, and restart the TV and Mac. Apple also recommends checking that AirPlay receiving is allowed and that Home settings are not restricting access.
Mirror an Android phone to an LG TV
LG’s Screen Share instructions use the phone’s notification or quick-settings panel, but Android manufacturers label the control differently. Common names include Screen Share, Smart View, Wireless Display, Cast, or Screen Cast. Similar names do not guarantee the same protocol.
- Open the LG TV’s Screen Share or compatible receiving feature.
- Open the phone’s quick-settings panel.
- Select the phone’s screen-sharing or wireless-display control.
- Choose the LG TV from the available devices.
- Accept the connection request on the television.
- Test orientation and audio with ordinary, non-sensitive content.
If the phone only offers Google Cast and the LG TV only offers Miracast-style Screen Share, the devices may not connect directly. Use a supported app-level Cast target, a compatible external streaming device, or HDMI rather than installing an unknown receiver app.
Use Google Cast on a supported LG TV
Google’s current Cast help says compatible LG televisions can expose a Google Cast button in Home Hub. This does not mean every LG TV has Google Cast.
- Open Home Hub on the LG TV and look for Google Cast.
- Enable or accept the Cast terms if the television presents them.
- Open a Cast-enabled app on the phone or tablet.
- Tap the Cast icon and select the LG TV.
- Start playback and use the source device as the controller.
If Home Hub does not show Google Cast, verify the model and firmware. Do not change the TV country or install an unofficial package to force a feature that the model does not support.
Mirror a Windows 11 PC to an LG TV
Microsoft’s current wireless-display instructions use Miracast. LG’s 2025 guide uses the same Windows + K flow on a supported PC and television.
- Turn on Wi-Fi on the PC and open the LG TV’s Screen Share or wireless-display receiver.
- Press Windows + K on the PC.
- Select the LG TV from the Cast list.
- Accept the connection prompt on the television.
- Press Windows + P to choose Duplicate, Extend, or Second screen only.
If Windows + K reports that the PC does not support Miracast, a software download will not necessarily add the missing hardware capability. Use HDMI or a compatible wireless-display adapter. Windows 10 reached the end of free support on October 14, 2025, so current troubleshooting should be based on Windows 11 where possible.
Use HDMI when wireless mirroring is unavailable
- Identify the source device’s supported video output: HDMI, USB-C video, Thunderbolt, or a manufacturer-supported adapter.
- Connect the adapter and HDMI cable to the source device and television.
- Select the correct HDMI input on the LG TV.
- On Windows, press Windows + P to choose the display mode.
- Confirm audio output is set to the TV if sound stays on the computer.
Not every USB-C port outputs video, and not every inexpensive adapter carries audio or protected video correctly. Check the source-device manufacturer’s specifications before buying an adapter.
Troubleshooting checklist
| Problem | Check first | Next safe step |
|---|---|---|
| LG TV does not appear | Exact receiver feature, same Wi-Fi, guest-network isolation | Update and restart both devices; verify the model guide |
| AirPlay code repeats | Correct TV selected, AirPlay permissions, network stability | Stop mirroring, restart, and reconnect once |
| Android sees no receiver | Whether phone and TV use the same protocol | Try app-level Cast, a compatible device, or HDMI |
| Windows says Miracast unsupported | PC hardware/driver support and TV receiver | Update drivers or use HDMI/a supported adapter |
| Video plays but screen is black | App’s official output rules and native LG app availability | Use the app’s documented AirPlay/Cast route or TV app |
| Audio is delayed | Wi-Fi congestion, distance, sound output path | Use 5 GHz where suitable, reduce distance, or use HDMI |
Network fixes without resetting the TV
- Confirm both devices use the same router and not separate guest or extender networks.
- Move the phone or computer and TV closer to the router.
- Pause a VPN on the source device while diagnosing local-device discovery; reconnect it after the test if required.
- Restart the source device, LG TV, and router in that order.
- Update webOS, iOS/iPadOS/macOS, Android, or Windows before changing advanced router settings.
- Test HDMI to separate a wireless-discovery problem from a display or app problem.
For a wider TV network diagnosis, use Smart TV Not Connecting to the Internet?. Avoid a factory reset until model support, network isolation, software updates, and a wired fallback have been checked.
Privacy and safety
- Do not mirror private notifications, passwords, payment screens, or work data in a shared room.
- Verify the TV name before accepting a code or connection.
- Reject unexpected mirroring prompts on the television.
- Disconnect after use on a hotel, classroom, office, or other shared network.
- Use only built-in platform features, official apps, or manufacturer-supported adapters.
Screen mirroring is a display connection. It does not supply a subscription or override copyright, regional availability, DRM, or account rules.
Frequently asked questions
Do all LG TVs support AirPlay?
No. LG documents AirPlay on supported models and notes support beginning with certain 2018 webOS 4.0 products, but the exact model, region, and firmware determine availability. Check the TV’s user guide and AirPlay settings.
Can I mirror Android to an LG TV without Wi-Fi?
Some compatible Miracast-style connections use Wi-Fi Direct, but both devices still need compatible wireless-display support. A normal shared Wi-Fi network is recommended for reliability. Use HDMI when the protocols do not match.
Why does my phone have Cast but my LG TV does not appear?
The phone may be looking for a Google Cast receiver while the television offers a different Screen Share protocol. Check Home Hub for Google Cast and verify the model. Similar menu names do not make the protocols interchangeable.
Can I mirror through a Fire TV device connected to the LG TV?
Possibly, but that is a Fire TV workflow rather than the LG TV’s native receiver. See How to Screen Mirror to Firestick for the supported Android and Windows routes and device limitations.
