Ergotron is pretty widely considered the gold standard in monitor mounting hardware. Their solutions are some of the best, longest-lasting, and most reliable out there. I personally own two monitor arms from the company that are almost old enough to drink, and neither shows any signs of sagging or wear, despite having held many, many monitors over the years.
While more budget-friendly options do exist, and are likely the right choice for the majority of users, a beefy, heavy-duty solution is required for those with the largest displayl bigger ultrawides, or even super ultrawides, like Samsung's Odyssey G9 lineup. That's where the Ergotron - HX Single Ultrawide Monitor Arm comes in. It's specifically designed to handle the weight and torque created by the largest, most curved displays.
Supporting monitors of up to 49 inches and weights as high as 42lbs, this unit is one of the very, very few on the market I'd trust to hold up something like an Odyssey G9 Neo or an interactive pen display like the Cintiq Pro 24". Of course, this amount of extra material and sturdiness comes at a cost. But, if you're spending $1,500 to $2,000 on one of the monitor form factors this arm is intended for, you don't want to cheap out on how you mount it. That couple hundred dollars you saved will be small comfort as you watch it come crashing to the ground after an inferior mount fails.
- Holds up everything up to and including super ultrawides and even some big-screen TVs
- 10-year warranty
- Still only takes up a tiny amount of desk space, even while holding massive displays
- Tensioning system can support a huge range of monitor weights
- Built-in wire management keeps your display's cable well organized
