Apple TV 4K Random HDMI Signal Loss

I have had more than one problem with apparent compatibility issues between AppleTV 4K and my LG OLED55B1PUA television.

For at least two years it was a serious lag between the Apple TV 4K’s (both 2nd and third gen) Siri Remote and AppleTV 4K (second and third gen) itself.

Turned out it was an apparent (signal) incompatibility between Apple TV 4K and LG TVs.

I suffered that extremely annoying problem for about two years and then one day, despite everything I tried, the problem just disappeared all by itself!

Was it Apple or LG or both and does it matter? It seems the problem was solved, right?

So for the last couple weeks (after an Apple TV 4K TVOS update, I am having a new and different issue with Apple TV 4K (3rd gen) flickering off and on (lost video signals) to the same LG TV. I researched it and found many others (again) with the same issue I am having.

No surprise.

But here’s the kicker. In both cases, the other users with the same issues offered the same solutions despite the problems themselves (switch the cables, move the devices further apart etc.) ALL had LG TVs. Most, if not all, of them LG OLED TV’s of various configurations.

I have to question if the problems mentioned between LG and Apple devices is and has always been Bluetooth (or other signal incompatibility issue) and will eventually be very quietly solved by software updates by one or both companies without acknowledgment.

The point being that I tried all the solutions (once again repeated for either issue) to have been a complete waste of a couple years worth of efforts and easily hundreds of dollars.

Is it LG, is it Apple or both? Does it matter? This is getting ridiculous.
