The setup on the earlier monitors was sometimes call

As a counterexample my first PC monitor had nothing like that. It was a
dual-frequency B&W CRT and only had three controls: a power-on switch, a
brightness control rheostat and a contrast control rheostat. That was it.
It accepted both interlaced and non-interlaced analogue video input, 0.7V
p-p, separate sync. Earlier on I came across numerous digital (TTL) input
PC monitors and they had similar controls. Some had additional rheostats
to adjust vertical position and sync. There was no setup in any of them.
