I have a note 10 and I am able to connect it using USB c to hub with hdmi. It displays the correct time and a lock with black background. I move the mouse or press up and down button on mouse and nothing happens. I don't have a keyboard connect it to it. I watched YouTube videos where you can draw the pattern using mouse. But it won't go to the pattern screen on my monitor. The screen phone is black all the time so no help there. Back button on my mouse by passes the lock and time screen on my note 9. How can I get the note 10 to display the screen pattern button I see on YouTube videos on my monitor?
