put virtual camera in 1080x1920 mode

friends I have a problem, when I want to put the virtual camera vertical, it looks deformed because the output remains horizontal (1920x1080). Is it possible to do some configuration to use the virtual camera in vertical mode?

I attach pictures of the problem

Same problem here, but unable to have any solution till now. Somehow recently for once this problem was sorted out for me but after installation of Splitcam it again started to squish output resolution
