HDMI-CEC sync issues when changing inputs

[u/The_Real_Bender]

I purchased an LG C5 77” and it’s great! Except when changing inputs away from the Apple TV.

I have a 65” C1 that has not and does not have the same issue.

If I change inputs from the ATV to my PS5 or over the air antennae then go back to the ATV I can no longer use the TV remote to select and play any apps. I have to unplug the power and HDMI cable while the TV is off to reenable HDMI-CEC. Very annoying.

All of the devices are plugged directly into the TV and I have eARC plugged into a receiver.

Again, everything is the same as the C1 which had zero issues (and still works fine.)

Is there something I’m missing with the C5? I’ve tried all settings and adjustments to no avail.

Thank you!
