Which Chromecast hardware are you using (if any) ?
Thanks for your patience and best regards,
Thank you, ***** ***** don´t think that your problem is the actual plug, but your Windows setup. So buying a new one is not going to solve the problem I think. A remote-connection would be the best option in this case, so that I can fix it up for you. What do you think?
