"Scale GUI" Option Causes Black Screen

[Zilch]

My menu GUI was stretching weirdly across my four monitors, so I checked this box and now all my screens go black after a microsecond flash of the big "DCS" logo loading screen.

 

Is there a way to shut this off outside of the client, or perhaps to force the client to go back to 100% graphics default settings without using the client?

 

EDIT: I have Notepad ++ and have options.lua open and ready to edit.

change:

["scaleGui"] = true,

to:

["scaleGui"] = false,

Tried that...seems like when I load the DCS client, it overwrites changes I made to options.lua.

 

Or, I'm completely insane.
