Use the weight without the original stand
A monitor specification may list both an assembled weight and a weight without its stand. For an arm installation that removes the stand, identify the latter. Account for any added bracket or accessory according to the mount manufacturer's instructions.
Keep kilograms and pounds clearly labeled. Convert once and keep the original number alongside the conversion. A number copied without its unit is an avoidable source of mistakes when comparing US and international documentation.
A larger maximum is not the whole answer
Some adjustable arms specify a minimum as well as a maximum supported weight. A display below that range is not confirmed compatible merely because it is light. The minimum is a product constraint, not a suggestion to add improvised weight.
Screen depth and the manufacturer's restrictions for curved or unusually shaped displays can matter as well. Read footnotes rather than treating the headline capacity as approval for every object below that number.
Assess each display separately
For a dual mount, check the limit for each arm and any total assembly restriction. Two screens with a combined weight below an assumed total can still fail an individual-arm limit. Confirm that you are reading the specifications for the linked variant.
If a screen sits outside any published limit or a relevant specification is missing, ask the manufacturer for a model-specific answer. Do not buy an arm on the assumption that tightening a joint will compensate for an unsupported load.
