Hello
I recommend the company Guntlin (Guntlin.ch). They have a large selection and very competent advice.

An exciting question! On Galaxus, for example, there is a VESA mount from Neomounts that allows monitors to be stacked. However, the reviews show that the monitor weight is often at the limit of what the mount can support.

The OLED G9 weighs around 9.2 kg without the stand. As a single solution, the Ergotron models are very suitable, but these may not be exactly what you are looking for. However, there are also alternatives from other manufacturers, although these often come at a price.

For example, we recommend the MonLines 251B or 250B as well as mounts from Putorsen. It is important to note that many VESA mounts have difficulties with a stable vertical tilt, especially with heavier monitors. It is therefore all the more important to keep an eye on the total weight of the monitor and hope that the manufacturer's specifications for the maximum load capacity are correct.

So if you are looking for a long-term stable solution, it is worth investing a little more in a high-quality mount - after all, the monitor should remain securely and reliably positioned.
