HDMI ports are automatically switching between each other.

I have a 65 Inch LG OLED evo AI C4 4K Smart TV 2024 - Model OLED65C4PUA.ACC. here have been a many weird things happening. This is one of them:

I have 2 HDMI 2.1 cables attached to a Rogers Internet TV unit (HDMI 4) and the other 2.1 cable plugged into an XBOX Series X (HDMI 3). If the TV is on an HDMI 4 is active, and I turn on the XBOX (HDMI 3), the TV begins to swtich back and forth constantly and never ends until I turn off the TV. It will automatically switch itself from HDMI 4 to 3, then 3 to 4, then back to 3 again non-stop.

If I power off the XBOX, this behaivor stops.

Would anyone know why this does that? Is this a software or hardware problem? I tried to describe this to LG Support but they had no answers.

Can you check if Auto-sensing feature is turned on in Settings Menu ?

If it is on, please turn off and see if the problem is resolved.

So it turns out this setting works, as the TV no longer tries to command any of the HDMI ports. However, I opted to keep CEC on, since one of the reasons I bought an LG TV and Soundbar was to enjoy the intergration aspects of them together, of which this is one.

90% of the time, this weird issue does not occur, and hasn't occured for several weeks now, so decided to live with it. I have been cognizant of HOW I turn on the TV now, that has reduced this issue, such as activating 1 port at a time, rather than simultaneously, which seems to help. I don't mind if it auto-swtiches to the XBOX when it turns on, which is probably what I was wanting. So will let this issue slide for now.

Thank you for the help.

You are welcome.

Glad to hear that you are not facing the issue very often.

In the future, if the problem persists then raise a issue ticket with LG Customer care
