Are gas assisted monitor arms better for heavy monitors?

To cope with the weight of particularly heavy screens, heavy duty monitor arms are commonly designed with gas springs as opposed to simple articulated joints.

Gas springs, like the one in your office chair, need to meet resistance before they depress, so this means that until your monitor is attached and its weight begins to have influence you won’t be able to position the arm in the position you desire.


Are all monitors compatible with monitor arms?

The vast majority of monitors will have no problem as they are VESA compliant, meaning they have 4 screw points on the rear of the monitor in a formation that is standardised across most manufacturers. 

However not all monitors can be attached to a monitor arm. Apple products for example are not VESA compatible as standard however can be modified with a VESA mount adapter for 24″ and 27″ iMacs, all Thunderbolt displays and LED Cinema Displays.
