So I've had an issue present itself with the "magic" remote for my C8. It powered up the TV the first time just fine, but after a software update, it no longer powers up the TV or turns it off. There was a software update for the remote after this, and another TV update. Still doesn't work. If I manually power on the TV with the button on the back, all other functions on the remote work (cursor, volume, scroll wheel, scroll button, etc etc). I tried unpairing and pairing it, no luck. Interestingly I turned on the voice commands from the remote and I'm able to use that via the remote to turn the TV off (press and hold the mic button and say "turn off TV"). Still have to press the button on the back of the TV to turn it on. Submitted a customer service request to LG to see if it's a known problem, but that was just yesterday.
The HDMI-CEC functionality is also funky as AIDS in that it randomly turns on my PS4 or BD player. XBOX ONE X doesn't have this functionality. It worked fairly well with my Samsung TV in that when I turned that off, attached devices turned off (receiver, BD player or PS4), and the built in IR functionality of the XBOX would turn on the TV and receiver when I turned that on. It plays very awkwardly with the LG TV.
That said, I'm sure I'll get it all sorted out, but after dropping a couple grand I was hoping it would all just work, and besides the remote and HDMI-CEC bullshit, it does. Just really annoying, especially when I have to tell the wife "turn it on from the button on the back of the TV and talk to the remote to turn it off" like wtf, really... It's like an 11/10 hot ass girlfriend who has never had a job and doesn't know how to drive.
