Frequently Asked Questions (FAQ)
Is it possible to connect a phone to an LG TV without the Internet?
Yes, Miracast and Screen Share don't require internet access; both devices need to be connected to the same router (even if the router isn't connected to a provider). However, streaming from online services (YouTube, Netflix) requires internet access.
Why does the video jerk or stutter when streaming?
This indicates low channel bandwidth or interference. Try moving closer to the router, turning off downloads on other devices, or switching to the less congested 5 GHz band.
Does my old LG TV support wireless connectivity?
Models made before 2012-2013 may not have built-in Wi-Fi or support for modern protocols. In this case, you can purchase an external Wi-Fi adapter (dongle) from LG or use a Chromecast or Apple TV connected via HDMI.
How to eliminate sound lag when playing games on TV?
For gaming, it's best to use "Game Mode" in your TV's picture settings, which will reduce input lag. However, for wireless audio transmission, a 1-2 second delay is a technological limitation of Wi-Fi and Bluetooth protocols and is completely unavoidable.
