Questions and Answers (FAQ)
Is it possible to connect a phone to a TV without WiFi?
Yes, this is possible with a cable. For Android and iPhone (newer models), USB-C to HDMI or Lightning to HDMI adapters are used. There are also special wireless adapters (dongles) that plug into the TV's HDMI port and create their own access point.
Why is only the picture being transmitted, but the sound comes from the phone?
It depends on the app and connection method. When mirroring your screen (Miracast), the audio usually comes through the TV. If you're using DLNA players, check the audio output settings in the app itself. Sometimes adjusting the volume on your phone during playback helps.
Does phone connection affect internet speed?
Yes, when actively streaming high-resolution video (especially 4K), the Wi-Fi channel can become heavily loaded. This can lead to reduced speeds on other devices if your router or ISP has limited bandwidth.
Is it safe to use third-party streaming apps?
Most popular apps are safe, but it's always best to download them from official stores (Google Play, App Store). Avoid apps with questionable permissions that require access to contacts or SMS, as these aren't required for media streaming.
