CRT range and vertical positioning
Milsancho:
So, please, correct me if I'm wrong, the safest/easiest way is just having two Groovymame installations, one for 15khz and another for 31khz.

Precisely what I would do in your case. Once you get familiar with GM, ini files, modelines, ranges etc. you will think of ways to optimize your setup, for example using scripts as Substring is suggesting.
NB: in my case using several ranges is a way to cope with geometry variations, as you correctly assumed.

Yeah, thanks. The problem with this solution is that it won't do for phase 2, with multi monitor games. But I guess it will be just a matter of reconfiguring one of the Groovys for it and adding a displayX.ini.
It still bugs me the several CRT ranges within a mame.ini thing, though. How Groovy knows which is the best suited for every game and for the particular geometry settings on your display if you don't tell it somehow. I feel like I'm missing something important to understand the monitor configuration aspect and experiment with confidence.
makya:
Regading Phase 2, it's better you gain experience first.
GM/switchres uses an algo to find the best mode allowed by the ranges you set. Do you understand every entry set in a range?
By the way, is your 15 kHz CRT a TV or an arcade monitor?
Milsancho:
Yeah, no hurries.
I think I understand all of them, though I'll get a better grasp about the porches and the pulses when I do some testing.
I have a PAL TV (RGB), but modifying basic geometry is not too complicated on it.
The only thing I'd really like to clarify before proceeding is how the Emu Driver installation might differ considering my setup. I've read that I should not unplug the 31khz monitor, but if I want the 15khz monitor on the VGA output, I have to. Unless that meant I should use both, the HDMI and the VGA outputs from the beginning (which goes against everything explained in Calamity's guide).
