⚠️ Warning: When using the "Cast" feature, your smartphone's screen may become very hot. This is a normal reaction of the processor and Wi-Fi module under high load. Allow your device to cool down if a temperature warning appears.
Frequently Asked Questions (FAQ)
Is it possible to connect Redmi Note 8 Pro to a TV without Wi-Fi?
Yes, it's possible, but it requires a physical connection. You'll need a USB Type-C to HDMI adapter. However, it's important to keep in mind that Redmi Note 8 Pro It has a USB 2.0 port, which doesn't always support video output through this port. In most cases, a wired connection requires DisplayLink technology and a special adapter with a chip, making this method less convenient than Wi-Fi.
An alternative would be to use a USB cable to transfer files to your TV if it supports reading external storage, but this will not be a live screencast.
Why is there no sound during the broadcast?
Lack of sound is most often related to the settings of a specific app or TV. Check that the volume on the TV itself isn't turned down. In some cases, when connecting via Miracast, sound may only come out of the phone's speaker. Try selecting "Cast audio" in the casting settings or switching the audio output device in Android by tapping the speaker icon in the notification bar.
Does phone connection affect internet speed?
Yes, it does. Since the phone acts as a video streaming source, it actively uses the Wi-Fi channel. If you're streaming a heavy 4K video, the available network bandwidth may decrease, which will be noticeable to other users, such as during online gaming or video calls. It's recommended to use the 5 GHz frequency to minimize this effect.
Is it safe to leave your phone plugged in overnight?
Leaving your phone connected to the TV overnight is not recommended for energy-saving and screen-life reasons (although the screen may turn off, some apps keep it active). Furthermore, constantly running the Wi-Fi module at high power can cause the device to overheat if it's in a poorly ventilated area.
