@Phil Hinton very interested to learn more about the below from Andy's 4th January news article about the 2022 LG TV lineup:
"Another new feature (due later in 2022 via a firmware upgrade) is Room to Room Share which enables the viewing of cable or satellite content on another TV via Wi-Fi without an additional set-top-box."
Hopefully this will be part of your long term testing. Really keen to see how this works in reality - what formats are supported (up to 1080p HD or full 4K/HDR/Atmos), how this works while the TV is in operation or not, whether there are any CEC type controls available from one TV to the next. One thing LG has consistently failed with is it's native sports apps. The Now app doesn't support 50fps unlike on Sony & Samsung and there is still no BT Sport app. Being able to hook up one satellite box, Apple TV or firestick and use it on any other supported TV sounds a winner to me rather than having multiple external devices on each TV.
Aside from that, enjoyed the video review. Looks a fantastic TV and will potentially be my B6 replacement once price come down a bit.
