Change Hz on j5create USB to HDMI adapter

I'm using a USB to HDMI graphics adapter to add another display to my laptop. https://en.j5create.com/products/jua350?...0609582020

I want to use this extended display as an input into a Blackmagic Design ATEM video production switcher but have to match the input resolution and frame rate of the switcher (1920x1080 59.94Hz interlaced or 29.97Hz interlaced). My nVidia card will output 59 Hz works with the ATEM.

But I need the j5create USB to HDMI adapter to work with it as well but only have 50Hz and 60Hz included in the drivers.

Will CRU allow this to work? I can't seem to make it work.

Thanks.
