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.

Step 1

Place your MSI monitor on a safe, soft surface to avoid damaging it during installation.

Take the M4x20 screws (screw bag SP14) and attach the VESA adapter to the back of your monitor using a screwdriver. (Figure 1)

First loosely screw in all 4 screws and then gradually tighten them.

Figure 1 Figure 1

Step 2

This is how the correctly mounted VESA adapter should look on your monitor. Please check again if all screws are tightened properly. (Figure 2)

Figure 2 Figure 2

Step 3

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: 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!

Step 4
