Review on Monoprice Workstream Dual Arm Adjustable Gas Spring Desk Mount - Silver, 15-34 Inch Monitors, Vessa 100x100, 19.8lbs Weight Capacity by David Monaco

Fits 24" and 34" wide screens. The full movement of the arms makes it easy to hold the screens side-by-side, pivot the smaller one vertically if needed to view documents, or slide it completely out of the way to use the larger one as a single monitor. The only downside is that my 34" display acts as a dock/KVM, so the number of cables going to the monitor far outweighs the built-in cable management channels on the brackets. The hand has no problem maintaining vertical or horizontal position, it has trouble maintaining tilt. The arm that attaches to the monitor and the base on the arm that it sits in could be firmer so it doesn't move left/right or front/back as much.
