Monitoring 1080p while recording 4k

Hello everyone in the community, i've got a question concerning the monitoring options i have during 4k recording with the new production camera.
I intend to built an onset/post monitoring solution out of a mac mini, UltraStudio Mini Recorder and the scope box software. The Mini Recorder only accepts sdi video signals with a resolution up to 1080p.
So my question is: can i output 1080p via sdi while i record 4k to the ssd?
This question is also relevant if you want to use any standard field monitor.
Your help is much appreciated!
