I am using an external screen for multiview
For several reasons I need that display in vertical
So, instead having a resolution of 1920x1080 is 1080x1920
vMix sends multivew output, but unfortunately stretches all the images to fit the screen
It is usable, but very ugly and may cause errors

I have looked in settings, but I can't find a solution

is there someone who could try to help me? Thank you so very much.
