Seems silly to take digital data, convert it to analog, ship it six

Well the receiving site was analog amps that where outputing high voltage to CRT R,G,B grids
to control brightness for the red green and blue guns.
There are still many analog monitors around.
I still have a nice one in the attic, my personal particle accelerator.
Still used in places:

I wonder how many people here are using a CRT monitor. Or know
somebody who does.

Did not we ship all old stuff to third world countries as garbage?
Some CRT monitiors, like tha old color Samsung I still have, were very good and brighter than the LCD I now sit in front of.
And I still use my old Trio analog scope with a real green CRT!
Also for playing old analog video of course:
https://panteltje.nl/panteltje/scope_tv/index.html after the WW3 nuking that will be great to know how to do,
with tubes of course, when all semi-conductors will be conductors...
In a way I regret throwing away my old BW CRT portable TV...
I had added a video input and it could display 80x40 text no problem from my Z80 system.
Analog video is still in use here from some of my security cams...
but digitally recorded...
