Just installed AI Sync Box 2 tonight

I'm stepping through the settings and I turned on the blank screen settings. I wanted the sync lights to turn off when the TV is off.

I have a Roku Ultra and PS5 connected to the sync box with a QN95B Samsung TV. I turned the Roku off which turns my TV off. After waiting x time, the sync lights are still on.

I've tried Googling for answers but haven't found anything that applies.

Does anyone have a tip?
