Question about Samsung C34H890WGR

Samsung Electronics GmbH
Hello,
thank you for your enquiry.
The Samsung Business Monitor LC34H890WGRXEN has a height adjustable stand (0 ~ 135.0 mm (±5.0 mm).
Grasp the top centre of the unit and carefully change the height. You may hear a noise when adjusting the stand height. This noise is caused by the ball slipping inside the stand when adjusting the stand height. This is a normal noise and not a malfunction of the unit. Refer to page 15 of the user manual for more information. You can access the user manual by entering the model code in the search bar on our manufacturer's page and downloading the user manual under the link "User manual and downloads" in the lower section of the product data sheet.
Kind regards,
Your Samsung Service Team
