Five monitor arms ranked on screen size limit and load rating, where the VIVO stacked has the largest screen size limit; the ErGear 33-inch dual is the cheapest route in.

12 min read5 products evaluated
Around $50 a monitor arm adds smoother height and tilt adjustment, and some dual-screen designs appear. Every pick cost 40 to 50 when we checked and lists the screen sizes and weight it supports.
The order reflects max screen size, max load per arm and monitors from maker specifications; a missing tension is flagged, not filled in rather than guess, since we have not benched them.
