This would approximate early television. oops.. now
I've mentioned
something from the 1920's.. but no one on this list probably has such a
mechanical monstrosity with (some kind of) a 'video' input. modern TV set
with built in tuner does not qualify -must be monitor not TV.
Folks are still building those beasts, Nipkov disks and all:

Well, now we're getting somewhere! Would a mirror galvanometer qualify as
a vector display? A Duddell oscillograph? An ondograph? That would put
the technology well into the 19th century. And the gizmos used by
Helmholtz to generate waveform patterns might even be construed as
graphical display devices....
