Unfortunately, although the [https://pinoutguide.com/Video/VGAVesaDdc_pinout.shtml VGA standard should accept Csync on pin 13], some monitors expect separate v-sync and h-sync signals. The NEC LCD 1970NX, which is often referred to as the perfect monitor for Amigas or Atari STs would be an example. In those cases, an adapter, that splits c-sync into h-sync and v-sync would be required.
