Hello Debbyspnet

No, 0 cm is not correct. The wall bracket alone has a distance of about 4-5 cm from the wall and then there are the fastening bolts. In my case, the front edge of the TV is about 10 cm away from the wall, but depending on the model of the TV, the distance from the wall to the front edge of the TV will vary.
But I personally don't find this tragic.

Something else that might be worth mentioning:
- You can easily pull the TV away from the wall and turn it to the left and right as indicated. In my opinion, however, turning the TV away from the wall is not really useful because you can only turn it a few degrees until it reaches the wall, so it doesn't really help much.

- It is stated that you can tilt the TV. This does not work for me. Of course, it's also possible that it's a misproduction or that my TV is too heavy for this.

I hope I could help you.

Hello Debbyspnet

The distance from the wall to the rear edge of my TV (Samsung QE65Q85R) is a minimum of 5cm.
Tilting to the left and right works well. As mentioned in another answer, tilting only works to a certain extent. For me, it worked with a little more force and two people (two people for safety reasons in case something didn't hold). Otherwise, the wall bracket does what it should.
