Hello I've looked in the forums but I dont seem to find a good ansewr to this. here it goes:


I'm sorry if this is not the correct thread to put it in.


I have a Radeon RX 470 and I try to use the Screen Mirror function on my Roku Stick but I cant use the function. I can however display Youtube videos to the Roku Stick from my PC (I have the youtube channel on the Roku Stick) If I use plex I can stream media and so...

So I discard any problem with the actual hardware I used DxDiag to see what was the problem (see attachment)


The most noticeable parts of the DxDiag if you dont want to download are the following:
