I recently bought the Q70R series Samsung TV. I like to cast to this TV from my Dell laptop running Windows 7, which is also connected to the same network. I am using Google Chrome (version 79.0.3945.79) on my laptop and I get the message "Source not supported" when I try to cast using Google Chrome. The software version on my TV is T-MSMDEUC-1335.0, B1970101/070204, BT - S. Can anyone help?
