Which bracket should I choose to put 2 monitors (one above the other)?

Question

Monitors

I already have 2 monitors (one is Benq GW2780 in landscape orientation, the other is Benq gl2460 in portrait orientation). I want to buy another Benq GW2780. But there is not much room left on the table. There was an idea to put a new monitor above the main old one. But I don’t see fasteners for such an arrangement (maybe I’m looking badly). I saw these only on Amazon, but delivery to the Russian Federation is too expensive.
Can you recommend a mount (necessarily desktop, I don’t really want to spoil the wall) for such an arrangement of monitors (mount for 2 monitors one above the other / mount for 1 monitor located above the main one / mount for 3 monitors at once)? Preferably not very expensive.

Answer 1

Any one you like , I have 2 of these , I'm fine. They have a gas spring, they hold up to 18 kg, they are adjustable for the weight of the monitor, the mount rotates in three planes
