late last year bought 43" lg uh620v tv. (about 15046/48) noticed availability of 'cast device' when right clicking on video file. tried degree of success standard definition video cast , play on tv hd played few seconds , stopped. with 15055, tv device found when right clicking on file cancels (disappears) when tv selected. is else seeing or have messed somewhere. i tried on samsung tv , worked build 15055. @ first, not see it. then opened file explorer , has private network , turn on file sharing . after that, see tv, after right-clicking video file , choosing cast device. now tv shows under bluetooth , other devices in settings, under devices , printers in control panel. mine clean install of 15055, may have file sharing , private network on, seems enabled work me. is tv plugged ethernet or wireless? ethernet should enable hd work better or connection more stable.
