After adding a mini monitor (1366 x 768) below my main one (1920 x 1080) I finally managed to export MFD screens for my usual planes and helos.

but the control indicator windows were sent to the mini monitor and clipped... instead of staying in the main window as they were before:

I found a post in the forums and did some experiments, relocating to the main view

planes are: F/A-18C, F-15SE, A4E-C, and helicopters OH-58D and AH-64D

included in the 7z file is a word document and the lines I did modify

the files are usually located in
SteamLibrary/Steamapps/common/DCSWorld/Mods/Aircraft
search for you plane (ie, FA-18C)
/.../FA-18C/Cockpit/Scripts/ControlsIndicator

you will find the ControsIndicator_page.lua file, rename and replace (back up first)

for the A4E, its located in your savefile DCS mods directory
for the OH-58D the file has a diff directory structure
/.../OH-58D/Controls
