Now the flaw: when the TV mounted horizontally on the wall, undresses him and rotated 90 °, it is crooked ("tipping" to the right). This can be compensated for, although what I have done, now it hangs extended horizontally, but retracted it wrong on the wall.
Not really bother me, but might be visually unattractive in other rooms already.
Still one of the other comments: If I buy a bracket max. 55cm can be extended, but each would have to be clear that a TV from approximately 110cm width can not be rotated by 90 ° .... People think it a bit after! The suitability of 55 inches but refers to weight and assembly.
Conclusion: low and stable, but for the large living room for some reservations - both only partially suitable.
