Recently I developed problems casting from my laptop (especially from youtube) onto my Samsung Smart TV before I would normally cast from google chrome but not anymore whenever I selected the option to cast tab from the google chrome menu and there was an error message of no devices found.I can still cast to TV from my Lenovo TAB 3 7 Essential tablet though.I reset the TV three times and the problem remains the same.The device name was changed only once. I am also experiencing problems with buffering from screen mirroring as well.Please advise me on what to do next.Thank you.
What's the model code and software version of your TV? Go to Home > Settings > Support > About This TV. If it's a slightly older TV it may be Menu > Support > Contact Samsung.
