It depends on the monitor/TV set, I believe. In essence, they work the same internally.
Back in time, our TV sets had no composite (CVBS) inputs, just an RF input.
That was an integrated composite monitor+VHF tuner combo, so to say.
In contrast to TV sets, pure composite or monochrome monitors were sometimes called "video monitors".
Quality monitors also had comb filters, which did set them apart from cheap 90s era TV sets with those red, black, yellow jacks.
RGB/SCART is a special case, perhaps, not sure.
Ediit: Video monitors also had knobs for v-hold,h-hold, v-size, h-size, 50Ohms/75Ohms inputs, etc.
