After scoffing at others complaining about their black screens via HDMI, I flipped on my TV last night and scrolled down the HDMI input list only to discover a black screen. Would not respond to keyboard or touchpad and I finally gave it a power cycle -- no luck. Went back to the TVs bluetooth remote only to discover I had inadvertently scrolled down to an unused HDMI input. TV and Mini were working perfectly, my brain was not. While I don't doubt that there are legitimate gripes about HDMI issues, there are also a number of problems related to user-error.
