Independent testing
How much independent testing exists for each monitor arm
Of the 7 monitor arms we track, 3 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| Jarvis Single Monitor Arm | 1 | 7 | 1 |
| Ergotron LX Pro Desk Monitor Arm (Matte Black) | 1 | 5 | 2 |
| HUANUO Single Monitor Arm Mount HNSS6 | 1 | 1 | 1 |
| Ergotron HX Desk Monitor Arm (Matte Black) | 0 | 0 | 1 |
| HUANUO Dual Monitor Mount HNDS6 | 0 | 0 | 2 |
| Mount-It! Full Motion Dual Monitor Desk Mount MI-2752 | 0 | 0 | 1 |
| VIVO Single Monitor Arm Desk Mount STAND-V001 | 0 | 0 | 1 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Monitor Arms buying guide and the reviewers we cite.
