Key Differences
| Feature | Ergotron LX | Fully Jarvis |
|---|---|---|
| Adjustment type | Spring tension (hex key to set) | Gas spring (one-handed) |
| Typing stability | Excellent — minimal vibration | Good — mild vibration at extension |
| Weight capacity | 25 lbs | 20 lbs |
| Tension adjustment | External screws — no disassembly | Internal — partial disassembly |
| Finish | Matte aluminum | Matte aluminum |
| Desk clamp range | 0.5-3.5 inches | 0.5-3.5 inches |
When Ergotron LX Wins
The Ergotron LX is the better choice when:
- You type heavily on the same desk as the monitor
- Your monitor is between 20-25 lbs (ultrawide)
- You want to set and forget without readjustment
The spring-tension mechanism provides four independent adjustment points, each lockable with a hex key. Once set, the arm holds position without drift for months. This translates directly to typing stability — the arm has no gas spring to compress or rebound under desk vibration.
When Fully Jarvis Wins
The Fully Jarvis is the better choice when:
- You adjust monitor height multiple times per day (sit-stand desk users)
- Your monitor is under 20 lbs (most 27-inch and under)
- You value one-handed adjustment over maximum stability
Gas spring adjustment means the arm moves where you push it and holds. For sit-stand desk users who raise and lower the monitor with their posture changes, this is significantly more convenient than Ergotron's stiffer adjustment.
Our Pick
The Ergotron LX wins for typing stability and heavier monitors. The Fully Jarvis wins for height adjustment convenience. Both are quality arms — the decision comes down to whether you prioritize stability or adjustment ease.
