在b站观看视频时，翻转屏功能为我们提供了更加沉浸式的大屏观看体验。 Many users hope that after flipping the screen, the screen will automatically display, so as to extend the interactive atmosphere and fun on the mobile phone.

第一步：打开B站App，进入目标视频播放页面。找到并点击播放器底部的“弹幕”开关，确认当前弹幕已前前前电影。 This is a prerequisite——若原视频未开别弹幕，年屏后将将内容设计开幕内容。

The second step: Click the “···” more button on the video in the right corner of the video, select “Pick screen” in the lower menu. Then enter the device search interface, select and connect your target device (such as a smart TV, projector, or display terminal that supports DLNA/AirPlay).

The third step: After the screen connection is complete and the playback is started, if it still does not appear, please switch to the screen device operation. There are slight differences in the device path of different brands and systems, but usually you can find the relevant options in the system settings or screen control panel.

Pay attention to the functions with similar names such as "投屏 display setting", "弹幕 synchronisation" or "interactive content display", etc., and turn them on.

Supplementary note: Some high-end TV or customization systems (如小米PatchWall、巴头鸿蒙Cast+、海信VIDAA etc.) also provide independent 分幕 style to adjust the input, for example, turn it on in “Video 单屏工作”→“分幕式年法法”.

After completing the above settings, when you use the B station to cast the screen, the 强幕便会 will be displayed together with the video by default. Whether it is 追番制剧, 围观鬼畜神剪, or learning science courses, you can simultaneously experience the unique charm of 幺幕 culture on the big screen——real-time comments, interactive fun, and collective feedback, all in one.
