How to set clock to display when Infotainment is Off (on CX-50)?

Hello all! I'm happy to be a new CX50 owner!
While getting myself up to speed on the Infotainment system, I saw a You Tube Video showing how to have only the Clock displayed when the infotainment is turned off (a blank screen with just the time is showing).
Unfortunately I cant find that video again and was wondering if someone could share how to set that display?
