Rekordbox DJ Video - HW output

Hi,
I would like to use Pioneer CDJ Nexus 2 and DJM 900 Nexus in HID mode to control rekordbox DJ software with video.

How is the video output done?
Can I route the video output of Macbook hdmi out to route it to LED screens?

Or how it works with video outputs?
I cannot find any info about, how the video output is done in a hardware way.

Thanks for help!
