The screen is not quite pinned to the wall because of the cables but this is not a problem on the visual effect rendered we do not realize it.
I had to fill the void of the insulation between my cinderblock wall and plasterboard with scantlings as specified in the instructions, because it's true you it a weight cantilevered once unfolded the wall, plasterboard would not resist.
A little tinkering is necessary for the installation, but a "Sunday handyman" is quite capable of performing this installation.
I also installed a LED light strip on the back of the TV to create an atmosphere when the TV is on and the effect is more quefficace.
