My tv was turned off and all of a sudden it randomly turns on with a message saying to “LaptopM256 is trying to connect” it gave me the option to allow, not allow, block, or always block. I chose always block but have never seen this before. No one in my house was trying to screen mirror or anything. I chose always block but I’m concerned to use my Roku tv now. It happened so fast it said it was a laptop and it had numbers and letters after it. Has this happened to anyone? If so what did you do? What can I do to protect myself
