HDMI is considered digital: the only signals are bits. I don't consider my display to be analogue, but it is arguable. It is an LCD.and has HDMI in. I know that this seems silly. The reasons for it are historical. At no point in the evolution was a blank page employed. At least that's how I understand it. (If I got to do a blank page design, I'd eliminate refresh as we know it. I'd just have a stream of screen updates. I admit that that isn't not the simplest way of transmitting movies. Without care, it might also look weird.)
