Can anyone tell me how I can tell if my HDMI port is faulty. I go through the hack on my 2016 ILX premium package and get to the screen that say HDMI. I click it and instead of screen mirroring I get 2 black screens. Tried to different hdmi cords so I know it's not the cords. I have a galaxy s9. Is it the port, a setting on my galaxy, or can I only use Apple? I saw on other posts people using Android phones so think it must either be a phone setting or bad hdmi port. Any help would be greatly appreciated. I can send a video if need be.

It may also need a special HDMI cable
