There are blanking intervals with HDMI. 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.)
