Please note: Not all VESA adapters and monitors are designed for vertical (upright) orientation. This limitation is often due to the specific geometry of the adapter or monitor. Do not ignore this information, as the load limit of the adapter can quickly be exceeded if not installed properly.

We are continuously working on developing monitors and adapters that are also suitable for vertical orientation.

However, monitors are designed for horizontal alignment by default.

Horizontal Mounting: YES

Step 2

Now attach the 3idee VESA adapter to the metal mount and screw it tight with the supplied M4x20 countersunk screws (SP8). (Figure 1)

Figure 1 Figure 1

Step 3

This is how the mounted VESA adapter should look now. Please make sure that you have tightened both screws. (Figure 2)

Figure 2 Figure 2

Step 4

For this step we recommend a 2nd person.

Now lift the monitor and hold it to your monitor mount. Fasten the VESA adapter with the 4 included M4x14 screws (screw bag: SP8 or SP2).

It is best to fasten 2 screws diagonally first, so that the monitor cannot fall down and you can fasten the remaining screws without any effort.

ATTENTION: Pay attention to the right screws!
