Wall mount monitor so hard to find?

I have recently bought a monitor for my Playstation 4 and a TV armchair with which you can lean back infinitely. I would like to attach my monitor to the wall so that I can pull it close to me if necessary. Is there no wall mount which has a long arm is infinitely adjustable. So that you can handle it very flexibly.

Monitor size 24 inches.

How long do you mean?

Of course, there are these wall mounts but above a certain level (do not know what's in your head rumschwirrt) makes it no more sense and looks ugly

Have you ever looked for "TV wall mount"?

Now I tried to explain it with a small drawing. If you have the seat in a lying position you have to put it on even closer if necessary adjust the height. For example, should be mounted sideways on the wall.

Yes, but see picture should be a bit different than the offered

See photo comment Lg

I need a length in cm or meter as that looks there on the drawing.

Apart from the fact that it makes absolutely no sense how that is

Do you think that it should be just? So not on the side of the wall? It would be about 1 - 1.5 meters arm length possibly? Honestly, I'm here to possibly advice me how to attach my monitor so that it looks like the picture. Of course you can't begin to compare this with a TV armchair and a monitor on a wall but I would like while I'm sitting or lying and the feet above have the monitor can approach me (PICTURE LINK: https://www.amazon.de/...077P6Q5WX)

So you want a kind of DIY from the Drian workstation?

That we could not buy that way. The things you can buy are always for the largest possible group. Such a holder would not buy many and if someone wants to buy is also the question if you find the product at all. That's why no one will stand for such a thing.

I'll only think of DIY or a special assignment somewhere.

You can also modify an existing mount.
