Disabling Shkval and Abris when multimonitor? Possible?

I ran into this video on youtube, where someone has setup the cockpit with triple monitors

I use dual monitors with the Shkval.

But I can see on this video, that the Shkval and Abris screens in the virtual cockpit dont show a signal, while there ARE signals on the monitors. My setup shows signal on both the virtual cockpit and monitor. So I see two video signals.

Is there a setting, where you can disable the virtual Shkval/Abris view, while enabling the view on the external monitor?

I was just thinking to save some framerates.

That was what I remember:

We used to edit ViewportHandling.lua file (under "...\Scripts\Aircrafts\_Common\Cockpit\")

and add two dashes in line #81 like below:

[b]purposes 	 = {--render_purpose.GENERAL,[/b]

But the main problem was that this modification couldn't pass Integrity Check.

You should try this in anyway, maybe ED reviewed I.C. thing again.

Will try, thanks!
