700 Participants in Gallery Mode

Hey all,

I have a gig coming up that will need to have probably just 1 host account but will need to house 700 participants. This is be a Webinar I guess so that we can see all of the faces in gallery mode.

The client simply wants 4 TVs behind a speaker at a lectern. With just 49 ppl per screen, does Zoom allow you to scroll pages of participants in gallery mode?

Lastly, is there a 'mode' that keeps my activity out of picture and just lets the TV see the gallery? I don't want anybody seeing the toolbar, or what I'm doing in Zoom.

Thanks
