Wirelessly streaming a smartphone screen to a large TV screen has become an integral part of the modern multimedia experience. Xiaomi Redmi 8 owners often face the question of how to maximize the ability of the device to watch movies, games or presentations without unnecessary wires. Unlike flagship models, Redmi 8 does not support all modern protocols out of the box, which requires a more careful approach to setting.

This article covers all current ways to connect over Wi-Fi, including built-in features. MIUI We're going to look at not only the basic instructions, but also the nuances of compatibility with different brands of TVs, and the typical errors that occur when you first connect. Special attention is paid to optimizing signal delay, a critical parameter for gamers and fans of streaming services.

To begin with, determine which protocol your TV supports. - Current Samsung models, LG Sony is usually equipped with Miracast and DLNA, While budget devices may require additional adapters.Redmi 8 base MIUI 11/12 It has limited support for Wireless Display, which is important to consider when choosing a method.

If you've tried to connect before and have problems, check the firmware version of the TV. For example, Xiaomi Mi TVs. TV beforehand MIUI TV 3.0 had bugs displaying the screen of smartphones on Android 9 (which is used in Redmi 8.
