Should be an easy fix since they are seperate camera views, I wouldnt hold my breath though. The multiscreen feature has not been touched or improved since it was released. It has a lot of issues, correct field of view etc, even frame generation only works on the main monitor. Hopeful that all these get fixed for the 2024 release.
About frame generation i do not know
But with the method i refer to in this post you should be able to get some better result
And you will notice that zoom i less of an issue
