I bought 2 LG OLED TVs, a 77c2 and a 55b2 (2022 models), behind both need a 300x200 vesa mount.
Then I bought 2 wall mounts, 1 generic and this LG one. The LG mount is clearly the best.
Just check that the vesa standard (screw distance) is the same (300x200) and the mount is perfect. Although it is adjustable (it can mount other vesa standards), you don't have to do anything. And it is already ready for 300x200.

No, this construction is flawed and we have christened the notorious Nitfall at Interdisciunt
