I've installed a few Samsung Frame TV's. I have a customer who wants to install a 55" but wants to be able to pull the TV out and turn it.

What's odd is that Samsung website spec's say this TV has a 400 x 400 Vesa pattern, and I noticed it comes with those plastic mounting hole inserts. I figured those inserts were not used with the TV. I've never seen mounting holes other than the no gap mount. There's no way that Vesa pattern can be right! Or is it??

Anyone done this?

I figured I could probably use an in wall box and mount an articulating arm to the mounting holes that are on the TV used by the no gap mount...
