: Is this used for screen mirroring from a computer? 這是電腦上用來投屏的嗎？

: >What's the principle behind it? Is it a WiFi direct connection? 就是将你的视频讯号压缩成差不多彩色电视的信号传出去。你接收到的就是非常 low 的画质和色彩。我买过一个不是这个牌子的。直接退了。

: What's the principle? WiFi direct connection? 原理是什么？wifi直连？

: This is genuinely great. Whether watching movies at home or screen mirroring for meetings, it's incredibly stable and smooth, with virtually no delay. I even used it in my bedroom, through two walls, and it could still screen mirror smoothly, which really amazed me! Plus, the setup is super simple—just plug it in and use it, no need to mess around for ages. 这个真心不错，不管是在家看电影还是开会投屏，都特别稳特别流畅，几乎没有延迟。我隔了两堵墙在卧室用，居然还能流畅投屏，真的惊到我了！而且设置也超级简单，插上就能用，不用折腾半天

: So expensive. 好贵

: It's fine for watching TV or shows, but don't bother with it for office screen mirroring. I have a similar one, and the delay is unavoidable. 看电视，看剧用可以，投屏办公别搞，我有个类似的，延迟没法避免

: It would be a painful experience to use this as an extended computer screen because the delay is unavoidable. 用来当电脑扩展屏幕会痛苦，因为延迟无法避免
