Help on wall mounting 100 U70N

Hi everyone,

Proud owner of a new 100” u70

Yet absolutely stumped what my installer needs me to buy to get it wall mounted.

Turning to you resident experts on what I might need

Hoping I can swivel left right, and add my Switch, Apple TV, and bluray without having wires everywhere

Thank you so much for your guidance !! My non tech brain can use all the help it can get

🙏
