For those who just got the new LG OLED TVs, this is LG's TV mount. It's quite slim and your TV can be mounted as close to wall as possible.
From Beach Camera, their eBay store and Amazon store, shipping is FREE.
Some people found their wall has wider pitch of studs than this mount. If you can work around the studs issue, or for those who has studs that match this mount, it is a good TV wall mount.
It's an open box, but Beach Camera says:
"This OPEN BOX product you are browsing has been inspected by our qualified technicians to ensure that it meets factory specifications and includes all factory packed accessories."
so, I guess this mount should work like a new one.
