Pro Pinball Ultra and DMD-DMDext

[odie]

I am new at at Vpin so please bare with me.  I have Fx2 setup and running perfect with Freezy's awesome DMDext. But I am struggling with setting on Pro Pinball.

I have a two screen setup plus a pinDMDv3.

Issues-

• For the DMDext I see there was a mention of adding a .bat file but I am not sure which file that is or where to add it. 
• Is it better to use the startup option via steam to add backglass and if so 2 or 3 screen? I assume DMDext needs to pull from something.
• Is the backglass that is provided the preferred or only option?
• Any chance that PinballX will add DMD mirroring within the frontend?

Freezy thank you for the product!!

Are you running it from steam?

My cab is 3 screen

in steam under the property's from the app I added m3 q

try adding m2 q

It is the Steam version. I am not sure how to proceed as I have tried the m2 and m3 setting.
