The wall distance is specified with 22mm. However, one has the opportunity to raise this with spacers. I had the problem that I mind. 25mm needed because the power cord at the back of my TV set and is not connected below. With the supplied spacers but no problem. The built-in bubble level I did not dare, and preferred to take my own. In comparison, the built-in level was also pretty good. The one negative is my plastic strips that are to be used to solve the TV from the wall / need. These are "dry runs" slipped through me with more. I have therefore replaced by conventional ropes.
Is the television on the wall, so you can still move it horizontally. If you want to correct the vertical, so you have two tracks that are previously screwed to the TV, first loosen and then adjust.
Overall I would recommend the bracket. It is inexpensive, yet well made. The accessories is extensive, only the plastic straps have been me too unstable.
