Questions, answered
How do I weigh my monitor?
Check the manufacturer's spec sheet for weight without the stock stand, since you will remove it. A bathroom scale works too: weigh yourself holding the monitor, then subtract your weight.
Why do ultrawides need special arms?
Width creates leverage. A 34-inch ultrawide exerts more torque on the arm's joints than a 27-inch monitor of the same weight, so arms need both higher capacity and stiffer joints.
Can I use a dual-arm setup for one ultrawide?
No. Dual arms are for two monitors. A single ultrawide needs one arm rated for its full weight and width. Do not split an ultrawide across two arms.
