I stopped thinking of HDMI as just a video cable after I turned on these 3 hidden features

I used to think HDMI was the most boring part of my entire setup. You plug it in, a picture shows up, and that's it. I have a soundbar I love, a PS5 gaming console I play every once in a while, and a TV that I paid way too much for at the time I bought it — all connected with a black cable I don't give a second thought to.
