Hello
I'm sorry, I have fitted the standard feet and placed the TV on a sideboard.
Therefore, I cannot give you an answer that can help you.

I hope you can find a suitable model.

Good luck

Otherwise, other suitable wall brackets are listed under "Accessories".

Hello, unfortunately I can't because I've been using the TV on stands up to now.
Sorry and LG
