Quote from the article website under warranty: Warranty extension On-Site The unit will be examined by a technician on site and repaired if possible. If it cannot be repaired immediately, it will be taken to the Service Centre. In the case of televisions, you will also be provided with a replacement unit.

Hello, we are talking about two different technologies. Indeed, 4K indicates the definition of the screen (3840 x 2160), Oled indicates the type of panel. We have here the best "quality" possible. Indeed, LCD screens are less contrasted.

Yes, the TV has an optical output for the sound = Toslink. Headphone output/Cinch is also available. SPDIF is not. Current AV receivers are connected to the TV via ARC HDMI and thus transmit picture and sound digitally.

Ambilight can be switched off, but it has never got on my nerves ;-) I am highly satisfied with Philipps. However, I have only played OneClickAdv. so far and everything is tip-top with it. All I can say about the two alternatives is that I deliberately chose Google as my operating system.

It worked perfectly for us (4K from Synology server via Oppo). But it probably also depends on the lan throughput. We have installed cat 6.

I have already answered the question about the bracket here. Blu-ray players are difficult to set up vertically, except for the Blu-ray player of the Xbox one S/X. I have not yet seen any others...

I have mounted the TV on the wall. It is important that the Vesa standard 300 x 300 mm is met and that the bracket can support at least 25-30 kg.
