Kantan Mapper in Portrait mode

Hi

I have an instalation I’m working on with 3 projectors in portrait mode, when I change the windows display properties on the 3 outputs to portrait and set the resolution in the Kantan edit window to match the kantan edit window crops the top and bottom of the output, with the edit window not being able to be scaled non proportionally I can’t find a way to fix this.

Any suggestions would be greatly appreciated.

Thanks
