So you joined yesterday and made just 7 posts all in this one thread - all wrong. As above youre transferring old knowledge (or myths) to new tech, Every one of the posters trying to help you here is very knowledgeable. There is nothing you can tell me about tech in general or C8 settings and usage in particular.The LG tv message comes up on screen every other day and it is too often. If you run screen refresh to many times it will degrade the tv.
I use smart sockets to turn stuff like tv AV Blu-ray all off so not left on standby as they still use a fair bit of power. If you do some research you will find all this out, and not just let items do what they want. You probably have LG tv settings all on when most of the enhancement settings apart from a few should be off.
We used the following calibration settings to review the LG 55" B8 (OLED55B8PUA), and we expect them to be valid for the 65" model (OLED65B8PUA) as well.www.rtings.com
