Fenix A320 CDU popout window does not match hardware MCDU

Hi,

I have recently bought a hardware MCDU which comes with a Samsung AIO monitor, which is capable of several common resolutions with either 16:9 or 4:3 aspect ratio. It is currently set to 1920x1080 and 16:9.
I did however also try other resolutions and ratios without success.

Unfortunately, I’m not able to find a decent position and size for the Fenix A320 MCDU image after popping it out with Alt+Gr. There is a larger black area on both sides on the text.

I have attached an image showing the popout of the Fenix MCDU → Image 1.jpg and I have attached another image showing the result after pressing Full screen–> Image 2.jpg

I think the problem is that the Fenix popout image has a different aspect ratio.
I know from Prepar3d times that such a thing can easily be fixed by changing the value in the panel.cfg file.

Do you think that this solution could also work here? If yes, where can I find the panel.cfg?
Or maybe there is a different solution?

Thank you very much!

Best regards
Andi

did you find a solution ?
