Best for Heavy Ultrawides

Ergotron HX Monitor Arm

Built specifically for heavy, large monitors including ultrawide OLEDs. If you have a 34"+ monitor over 20 lbs, this is the arm that can actually hold it without drooping.

$300-$350
Amazon
Pros
  • Handles monitors up to 42 lbs, covering nearly all ultrawides and large OLEDs
  • Same trusted Ergotron gas-spring mechanism as the LX
  • Widely recommended in ultrawide and battlestation communities
  • Confirmed working with heavy OLED panels like the Samsung G9
Cons
  • Expensive at ~$350, hard to justify for standard monitors
  • Overkill for monitors under 20 lbs
  • Large clamp footprint may not suit all desk edges
Why we recommend it

Yes, $350 for a monitor arm is a lot — but if you have an expensive ultrawide OLED, you don't want it crashing down because you cheaped out on the arm.
