I use one monitor format 4:1 with 16:9 resolution.
This monitor have the size of one RealDMD and uses HD resolution (1280x720) and show all windows desktop on the screen.
There are other old models with size 4:1 and 4:3 resolution (1280x1024) and show olny upper windows desktop os this type.
I set 1280x720 in all games, Visual FX2, FX3, ProPinball... and work perfect.
Pinball Wicked and Pinball FX DMD´s don´t support custom resolutions, only standart sizes, 128x32, 256x64, 512x128, 1024x256 or 1280x320.
For Pinball Wickd i use one Underlay to solve this because i can't use DMDExt.
For Pinball FX i have set to 1280x720 and Pinball FX says no, 1280x720 no, i show at 1280x320, them the DMD in this monitors looks very short.
Luckily we can now use DMDExt in Pinball FX and this solves the problem (when I manage to fix the glitch in the new Zen DMDs, Dotmatrix and Alphanumeric look great).
The exact resolution used for the DMDs is 1240x680 so as not to lose part of the DMD in the rounded corners of the furniture and it moves 20 horizontally and 20 vertically to center it.
I will try that version 2.1.2.9
Thank you very much
