Best Dual Monitor Arms

The Vari Dual-Monitor Arm is a clamp-on, pole-mounted arm for two monitors of up to 27 inches, with each arm rated to 19.8 lb. Tom's Guide named it the best monitor arm for two screens, citing its strong build and sleek design. It also found the setup slow and the clamp limited to desks about 2.25 inches thick. The Gadgeteer found it easy to install and very adjustable, and it kept the monitors secure on a moving standing desk. It suits people pairing two mid-size monitors with a standing desk. Those with thick or shallow desks, or larger screens, should look elsewhere.

The Ergotron LX Dual is the gold standard for dual monitor arms. Its all-aluminum build and patented Constant Force motion deliver the smoothest adjustment and the most rock-solid stability of any arm in this group, backed by a 10-year warranty. Reviewers across PCWorld and BTOD treat it as the benchmark. It costs more than budget steel stands and caps at about 20 lbs per arm, but for everyday dual-27-inch setups it is the most reliable choice.

The VIVO STAND-V002 is the cheapest mount here, a steel pole with two jointed arms that VIVO rates for two screens from 13 to 30 inches and up to 22 lbs each. PCWorld bought one and called it "easily the worst arm we've tested so far": both monitors move up and down together, every joint is set with screws and a tool, and a 10-pound 27-inch display made the arms sag slightly. PCWorld saw a use only for two 24-inch monitors that are set once and left alone.

The Ergotron HX Dual is the heavy-duty choice: a premium arm built to carry large, heavy monitors and ultrawides that would overload a standard LX. Reviewers praise its top-notch materials, finish, and engineering, with a 10-year warranty to match. It is the most expensive arm here and overkill for light setups, and reviewers note a touch of wiggle in the mounts, but for big-screen, high-mass dual configurations it is the most capable option.
