MonitorSetup LUA variables?

[dlder]

Sorry if this post is in the wrong thread; I've searched quite a bit, but as this is not a single-plane-question, but a DCS one, it should belong somewhere to "DCS World"^^

Here it goes:
I've setup my Monitor lua file for my main monitor + 3 MFDs.

Is it better to setup the displays like this:

Or like this? (less wasted space)

 

Anyhow, what I'm looking for are the "special variables", like

• LEFT_MFCD
• KNEEBOARD

or for the different planes:

• F14_HSD
• F14_VDI

So that I can assign the MFDs the way I want.

For instance, on the F-15C (Flaming Cliffs 3 module), only my left MFD is displaying a screen:

What are the variables for the other screens, so that I can display them onto the MFDs?

Thanks,
