With it running, I can swap between the two as often as I like without

When the PC wakes from sleep it'll rescan the monitors, because you might
have unplugged something while it was sleeping. It looks like the KVM keeps
telling the PC there is a monitor connected even when you switch away from
that input (as it should, to avoid unnecessary window rearrangement) while
the PC is running, but when the PC awakens it does a full rescan and decides
it can't make sense of what's attached and so falls back to classic VGA.

With the old Win7 PC, if I woke that up without it being selected, it was
on the wrong resolution. But could be corrected via display settings.

Sounds like a similar problem.

You might also be able to force the PC to output a specific resolution
irrespective of what the monitor/KVM says. It's a bit like installing a
Monitor Definition File on your Acorn. I've done that on Macs and Linux but
I'm not familiar with how Windows does it. There's probably an app for
that.
