I was curious about this -- I've been digging and I can't find a solution, is it possible to tell these things to jump straight to HDMI once you turn them on? Or are you always stuck with at least that one homescreen jump. Trying to make this thing as "dumb" as possible.
If you use any device that correctly uses HDMI CEC, then yes. I only have an Apple TV remote with some cheap Element Amazon TV, and I keep the TV remote taped to the back of the TV. Apple TV and Chromescasts will turn it on, off, and swap source to itself when used. I'd imagine Roku/Firesticks do as well.
