100 cm TV at right angles to the wall pivotally !!

Because of the many positive reviews I decided füt this wall mount. The requirement were:
Inclination angle of +/- 15%, and at right angles to the wall mounted. If the TV device is a product of LG with a total width of 100 cm. The product description did not indicate which of the TV width can not exceed for a 180 degrees swivel. In some reviews was a max. Width of 80 cm known. When fully extended bracket distance from the wall should be about 550 mm, therefore a 100cm TV would have to fit.

Product and result:
Processing very stabil.Beweglichkeit little stiff, but that does not and will certainly change with an increasing use something interferes.
Installation principle without any problems. Would be very helpful, however, a template for the drill holes have been. The support is quite difficult. The mark the drill holes is no template with only 2 people. Since the bracket in place while marking easy times. Since only long slots are available for the holes, but an exact positioning of the drill holes is mandatory. We decided after some trial and error to manufacture its own template.
This worked great, the holes were exactly in balance. A mark the drill holes without a template is with such a heavy mount almost impossible, especially as produced by Try black paint rubbed off on the wall.
Wall mount is now exactly in the "balance" (normal level, not the toy part)., Also in the completely extended state.
To swing at right angles (here is always written by the 180 degree swivel mE but is actually the 90 degree swivel much:
For us it was about 90 degrees swivel, so TV is at right angles from the "wall mounting" from.
And it is -with a trick possible. The TV is so hooked with the mounting rails in the front plate. When exactly centrally positioned this derkomplette swing is not possible (90 degrees perpendicular to the wall). Since my LG the hole spacing for mounting "only" 20 cm, the width of the front plate but about 54 cm, I was able to (viewed from the front) the TV on the mounting plate to the right move. The television is now hanging nich centered on the baseplate, but shifted to the right. Since the TV is wider than the mounting plate, you can not see the front. As a result, the right rail is now approximately 5 cm. from the "edge" that left about 23 cm. The TV is still without readjustment "in the balance". The 90-degree swivel succeed so perfect. I have attached a total of 3 photos for better understanding.
For hole spacing> 20 cm it might be tight with a 100 cm TV, as another move on the baseplate at remaining lateral distance of 5 cm is hardly possible. We have but fit and since the TV is quite easy, the TV is in spite of shifting to the right still in the balance.
Conclusion:
Price / performance ratio good, a template would be very helpful. Would I buy again at any time.
