Unfortunately, the mount is so flat that the cables come back against the wall and the connections can bend, I will adjust images for this purpose. We use DVB-C coaxial cable and is now something out.
So we placed 1.5cm thick wooden spacers behind the support, fortunately the screws are long enough and keep the anchors perfectly, despite modification. The tracks we got with washers little further from the TV off.
Conclusion: you have for ~ 21 euros a holder that holds the TV good, but you have to rebuild a lot, but that may be due to our flat TV model.
