New TCL update, in Settings --> Quick Start --> Screenless Service.

It says when activated, you can enjoy more background service.

Anyone know what this is ?

I'm also interested in this. Mine got this after the update, maybe Google Assistant works better when the TV is in standby? That would be great because it doesn't respond consistently to my "Ok Google..." command when in standby.

Yo, just confirmed it. That option seems to make my TV consistently responsive to my "Ok Google" commands while in standby. First thing I noticed is that USB ports used to have power that would turn on and off before and now those ports are always powered in standby. Should consume a bit more energy but likely isnt anything significant
