I frequently cast/screen mirror my Win10 laptop to my TV. Now, all of a sudden, when I try it won't connect. My TV will just go to the home screen, flash once & then just sits at the home screen. I deleted my device from the screen mirroring devices & re-detected it, still nothing. I wound up resetting the Network Connections on the TV & now when I try to cast, the RokuCast screen comes up like it used to (it had stopped even showing that), it says that my video is starting, the progress bar goes about 1/3 of the way & it just freezes there. I can't get past that point. It just ends up timing out on my laptop. Can anyone tell me what is going on & how to fix this??
