I'd like to be able to fully turn the front screen of the Action 4 while fully utilizying the back screen for control and recording display but it appears that is not possible - correct? Nearest functionality I can see is to have both displays turn off after a configurable amount of time while recording. Is this the case, that there is no way to have the front screen bank/black while only using the rear screen?

Set screen preview to single screen.  Second item in menu under snapshot.

Hi, DaveSp. Thank you for reaching out. As mentioned by skysailor64, just turn on the Single Screen Preview under settings. Should you need further assistance, please let us know.

Thanks - don't know how I missed that in the instructions!
