Finding LCDs at one time with response times sufficient for real time
stereo dispalys was a pain. Easier now.

Especially if it is something moving fast across the screen.

I am having trouble reconciling the above with the previous
claim that "no analog DVI interface for monitors exists."

That's not an answer to the question I asked.

I answered your question. It was a silly childish attempt at some kind of
test. My displays are running in military aircraft all over the world. Not
Mattell.

There is no such thing as an analog-digital anything. If you are having
trouble understanding that then go read the DVI spec again. It is simpy VGA
piggybacked on a DVI connector. . It is NOT DVI.

So blow it.

test over.

Cool down. There is some sort of misunderstanding going on. Guy
is a long term reputable contributor to c.a.e. You also appear to
be knowledgeable and helpful.

He is looking from a different perspective:-

You are looking the DVI connector spec for COMMERCIAL monitors (VESA)
Which have analog and digital interface on same connector.

He is ONLY thinking about what you would see as the DVI pins. (DVI only)

Once you have time for line, frame, active and resolution, you can work it
out.

e.g. dot clock is basically H pixels in H active time
line time divided by dot clock gives pixel counts per line
Non-active periods gives you relative position of active to whole line

Similarly V timings give you total number of lines and position
of active lines to vertical blanking and whole frame
