As someone wrote is generously dimensioned the VESA plate.
I also had the problem that my 24 "Samsung monitor has fixed his foot in a recess at the rear.
This was, as I had feared before the order, too small for the plate.
!!! So respect when the VESA device to the monitor / TV is recessed, this plate has a height of 120,3mm !!!
I had to increase the corner radii and about 3mm Material of the plate decrease to fit.
The delivery is complete, to M8 all VESA screw up high, dowels and wall screws are included.
If anyone can dowels a shelf on the wall, he should also have no problem to fix this holder.
However, I realized that only the mounting of the monitor does not lead to a "unique" seat.
Without the additional (beiligende) fixing screw the monitor can still easily move back and forth.
Apart from my monitor hangs with a slight downward angle. I think that is also the guide with the light game owed.
This could be but if it bothers you, easily countered by the relining with washers on the lower screws.
Anyway I am in spite of small defects of the opinion that you get a product here that his money's worth.
