The stand generates
heat. Why is that? Does
this mean that the
product is defective?
The upper part of the stand may become slightly hot at room
temperature. This occurs as the heat inside the stand releases
naturally. The intensity of heat you feel can vary depending on
whether the room is sealed or depending on the surrounding
temperature. This does not indicate a defect. You can use the
product without worry.
It is recommended to use the product in a location that offers
good ventilation at the back of the monitor stand.
