I have trouble imagining a set with separate horizontal sweep and HV --
especially a set with a reasonably sized CRT.

The "flyback" HV circuitry can certainly lose its regulation, while the
sweep
continues to work correctly.

CRT VGA monitors.

I said set, not monitor. And I assume you're referring to auto-sync monitors.
In a flyback HV system, you'd have trouble maintaining a constant HV as the
sweep frequency changed.
