The MSI MAG MT201D is a spring-assisted dual arm rated for two monitors up to 45 inches and 44.09 pounds each. Windows Central bought one for its own office, ran a 34-inch ultrawide and a 27-inch 4K monitor on it, and gave it 5 out of 5, calling it "the sturdiest, most versatile, and easiest to assemble monitor mount" its reviewer had used. The catches it found: the arms need room behind the desk to work, and the desk must be at least 10mm thick.

Full review
Bought, installed and used daily by Windows Central
Windows Central's Cale Hunt purchased the MAG MT201D for his own office and states that MSI had no input on the review. He mounted a 34-inch BenQ Mobiuz EX3415R ultrawide and a 27-inch Dell UltraSharp U2723QE on it and rated it 5 out of 5, writing that it is "the sturdiest, most versatile, and easiest to assemble monitor mount I've ever used."
He had everything together, monitors included, within 45 minutes, using the C-clamp rather than drilling through the desk. With the clamp hand-tightened using the included Allen wrench, he reported that shaking the base produced no movement at all.
Spring arms rated for 45-inch, 44-pound screens
Windows Central lists support for monitors up to 45 inches and 44.09 pounds per arm, VESA 75x75 and 100x100, up to 20 inches of vertical extension and 21.46 inches of horizontal extension. That capacity is why the reviewer could go back to an arm after switching to an ultrawide; his previous mount did not support wide screens.
Each upper arm has a built-in spring whose tension is set with an Allen wrench to match the monitor's weight. Windows Central found that with the right tension, monitors are easy to move and stay in place, and the tension adjustment helps prevent drooping over time. The head allows pivot, swivel, tilt and rotation, and the reviewer regularly swung his 27-inch screen between portrait and landscape.
Cable management and quick-release plates
Both sections of each arm have slide-away covers for running cables inside, which Windows Central says significantly reduces clutter so that only the cables next to the mount stand stay visible. The quick-release VESA plate attaches to the monitor first, then slides onto the arm and locks with a large thumb screw, making screen swaps easy.
Needs depth behind the desk and a thick desktop
The main limitation Windows Central found is space: the scissor-like arms need room to operate behind the desk, and the reviewer pulled his desk out from the wall by about a foot. Buyers with no room behind the desk may want a less feature-laden mount, the review says.
MSI specifies a desktop between 10mm (0.39 inches) and 35mm (1.37 inches) thick, and Windows Central recommends solid wood for maximum safety. It also notes there are cheaper arms available and that buyers who want RGB lighting should look at the MPG MT201DR instead.

Watch-outs
- −Windows Central found the arms need space behind the desk; its reviewer pulled the desk about a foot from the wall

- −No RGB lighting (that is the pricier MPG MT201DR)
How it compares
Its 44.09-pound per-arm rating and 45-inch screen limit, from Windows Central's spec table, are higher than the Ergotron HX Dual's 10-35 lb and 32-inch limits, the Ergotron LX Dual's 7-20 lb and 27-inch limits, and the VIVO STAND-V002's 22 lb. Its warranty is 3 years against 10 years on both Ergotron arms. Unlike the VIVO, which is screw-tensioned with no spring, each MT201D arm has a built-in spring with adjustable tension.
