Frequently Asked Questions (FAQ)
Why can't my LG TV see my phone via Wi-Fi Direct?
Make sure both devices are within line of sight (up to 5-7 meters). Check that Wi-Fi Direct is enabled in your TV's network settings (Settings → Network → Wi-Fi Direct). Also, make sure that airplane mode is not enabled on your phone and that mobile data is turned off, as it is sometimes prioritized by the system.
Is it possible to play games on a phone while displaying the image on a TV?
Yes, this is possible using screen mirroring. However, keep in mind the input lag. For fast-paced shooters or racing games, a lag of 100-200 ms can be critical. For turn-based strategy games or quiz games, this method is ideal.
Does Wi-Fi Direct slow down my home internet speed?
No, because Wi-Fi Direct creates a local network between devices, bypassing the router. Your internet connection remains free. However, if your phone uses a single Wi-Fi module for both connections (which is rare, but possible in bridged mode), the speed may be split.
How do I remove the "Connected" message from the corner of my TV screen?
In most LG models, this message cannot be removed, as it serves as a system indicator of an active connection. However, on some versions of WebOS, you can disable device connection notifications in the "Connected devices" section. Settings → General → Notifications.
