Hello! I now that there is a special service menu for the Samsung tvs for professionals. I want to be able to disable screen mirroring through that, is it possible and how? I also know that this will void the guarantee, but the warranty has expired so I don't care. If this isn't working I will buy a new tv, but not a Samsung one. The problem is disturbing neighbors trying to screen their phones. Is it possible to disable that so it's impossible to use the tv for screen mirroring? The device manager which should deny or allow incoming signals from phones, doesn't even work. I've an UE48H6705ST (2014).
