Active TV session prevents monitor from "sleeping" or power save

Running TV v.13.0.6447.  When I have a active session to a TV host computer the monitor(s) on that computer no longer "sleep" , go green, etc..  This happens on 2 separate desktop computers.

When there is no active TV session, these comptuers green the monitor as normal.

Is there a setting to allow them to green when an active session is present or is this expected behavior.

I'm not using the monitor driver and I'd prefer not to. I don't have a security concern, just trying to save some power by not having the monitor stay on / wake up during an active session.

Thanks.
