Auto Power Sync question

Recommended Posts

Hi, my first post here.


I have a "problem" for which I can't find a workaround. Please help.


LG 49SM8600 (webOS 4.5)


HDMI 1: IPTV from local provider (STB always on)

HDMI 2 (ARC): LG Soundbar

HDMI 3: Android box (Beelink GT)


I have Auto Power Sync turned on as I want the soundbar to be synced with TV's on/off state.


Also, the android box is synced (whether the box is on sleep or turned off).


The problem is that each time I turn my TV on input is automatically switched to android box (HDMI3) which I don't want.

I want it by default to stay on IPTV (HDMI1).


How to prevent this?

Excluding android box from auto power sync would also be a good solution but I can't find where to set this.

Turned off HDMI CEC on my android box.
It doesn't switch automatically to HDMI3 anymore, although now I don't have automatic power on/off, but I can live with that.
