本人也是索尼用户，昨天手贱进级的8.0，我也是服了，其时和你们一样问题，win10投不了，然后我就去找客服，没卵用。。。
捣鼓半天，客服给我发了个连接，让我手动更新固件。

这个是官方（中国索尼官网）公布的更新日记，居然移除DLNA/WIFI DIRECT ?? 其时看到我就发飙了，人家进级都是有新功效，索尼这玩意怎么越更新功效越少？ 问了客服半天，说不出个以是然，就一直回覆，我们没有删除DLNA功效。


厥后我怎么办的，我去翻外洋sony进级日记了

砸门首要看第四条， 大意是，不再支撑全时了，啥意思，就是你电视上得笑开屏幕镜像app，才能使用Minacast举行屏幕镜像。
可是dlna没有说起。厥后颠末测试，索尼电视不能在wifi连接下，dlna放视频。如图

厥后我改用了网线连接，成了。。




解决方案2：
电视上装个乐播投屏（我不是笑告白，不晓得有什么更好的软件），可实现wifi以及网线情况下的dlna，以及airplay。 windows下假如屏幕镜像需要另装软件（差评）。 最大弱点：乐播不能快进快退，不能长途节制，而索尼自带的dlna可以。


本身弃取吧，选用哪个 。。   实在用有线无线没太大区别，我这个电视鸡肋百兆网卡，又不晓得怎么root，没措施兼容usb千兆网卡，暂时没辙，去外国论坛翻翻没找到什么转千兆网的措施。。

注：
2. Newly added supported formats
The following formats are added as supported formats for USB or home networks.
Photo: .arw (files for simple playback only)
Music: .ogg, .aac
Video: .mkv (VP9 Profile 0, Profile 2), .webm (VP9 Profile 0, Profile 2)
External subtitles: .sami, .txt
Playback capability depends on home network server specifications.

这次8.0更新，dlna可以播放mkv视频啦~
不外在我测试中，索尼自带的dlna 放比力大的文件mkv会没声音（可是可以节制进退），  乐播有声音可是不能快进快退。

统统安好~~
