So through trial and error, I realized that when I used the HDMI adaptor, with two inputs into the HDMI adaptor, that I was able to toggle through the settings and use the LG TV remote to control the cable box. It needed a second input into the adaptor. So the only way it would work was with another HDML device, in which I thought of my old GoPro that had the HDMI port.
She saw the GoPro back there and is afraid I was using it to spy on her. I was hoping for support or a contact number an expert in this field to prove my innocence. Any help is appreciated.
