Ergotron LX Desk Mount Monitor Arm Matte Black
PRODUCT DESCRIPTION
Ergotron LX Desk Mount Monitor Arm Matte Black (45-241-224) - 10 Years Local Warranty
Ergotron LX Desk Monitor Arm — Premium Single-Monitor Ergonomics
The Ergotron LX Desk Mount Monitor Arm lifts a display up to 34″ off the desk and lets you set it at the exact height, angle and depth your posture needs. It comes in a stealthy matte black finish that disappears into a modern or gaming desk, and pairs that with Ergotron's patented Constant Force™ movement so the screen glides with a fingertip and stays where you leave it. For Singapore offices, home setups and gaming desks, it is the reference single-monitor arm.
Constant Force™ Motion — 33 cm of Effortless Lift
The LX arm gives 13″ (33 cm) of vertical height range and up to 25″ (64 cm) of horizontal extension, with 360° pan and 360° rotation between landscape and portrait. Ergotron's Constant Force™ lift-and-pivot technology means no knobs to loosen — move the monitor with one hand and it holds position, whether you are switching between sitting and standing or turning the screen to share with a colleague.
Holds Displays up to 34″ and 11.3 kg
Engineered for real work, the LX arm supports monitors up to 34 inches weighing 3.2–11.3 kg (7–25 lbs) on a universal VESA 75 x 75 mm or 100 x 100 mm pattern. The all-metal construction is rated to a 10,000-cycle motion test and backed by Ergotron's 10-year warranty.
Clean Desk, Tidy Cables, Fast Install
A two-piece desk clamp fits most desk edges out of the box, with an optional grommet mount for a permanent through-desk fixing. Integrated cable management routes power and video cables neatly along the arm for a clean, professional finish. Supplied by SourceIT with local Singapore warranty and a GST invoice.

Compatibility & Fit
Display fit. The LX Desk arm suits a single monitor up to 34″ weighing between 3.2 kg and 11.3 kg (7–25 lbs). Very light panels below 3.2 kg may not counterbalance smoothly; very large or heavy displays should move up to the Ergotron HX arm (to 19 kg / 42 lbs).
VESA mounting. The bracket fits the VESA MIS-D 75 x 75 mm and 100 x 100 mm hole patterns found on the majority of business and consumer monitors. Screens without a VESA pattern need a VESA adapter plate (sold separately).
Desk mounting. The two-piece clamp fits desk edges up to the thickness stated in the install guide; the optional grommet mount gives a permanent through-desk fixing for thicker or shared surfaces. Both fixings ship the arm ready for desks and benches, not walls — for a wall installation use the LX Wall Mount Monitor Arm.
Ultrawide and curved. Ultrawide panels are supported provided they stay within the 34″ and 11.3 kg limits; check the monitor’s own weight, because ultrawide and curved models are often heavier than flat panels of the same class.

Frequently Asked Questions — Ergotron LX Desk Monitor Arm
How do the LX Desk arm finishes differ?
Only cosmetically. This listing is the Matte Black finish (part 45-241-224); the arm is also offered in the other finishes in the ordering table above. Load capacity, motion range and warranty are identical across all three — pick the finish that matches your desk.
What size and weight of monitor does it hold?
One display up to 34″, weighing 3.2–11.3 kg (7–25 lbs), on a VESA 75 x 75 mm or 100 x 100 mm pattern. Heavier displays up to 19 kg should use the Ergotron HX arm instead.
Can I mount two monitors on it?
No — this is a single-monitor arm. For two screens use the LX Dual Side-by-Side or the LX Dual Stacking arm.
Does it clamp to the desk or bolt through it?
Both options are in the box: a two-piece clamp for the desk edge, or a grommet mount for a permanent through-desk fixing. Check your desk thickness against the install guide before choosing.
Will it fit a monitor with no VESA holes?
Not directly — you would need a VESA adapter plate for that monitor (sold separately). Most business and gaming monitors already have a 75 or 100 mm VESA pattern.
Does it work for a sit-stand setup?
Yes. The 33 cm of Constant Force™ lift lets you raise the screen when you stand and drop it when you sit, with no knobs to adjust. For a full sit-stand desktop workstation, look at the Ergotron WorkFit-TL.
Is local Singapore warranty included?
Yes. Every Ergotron LX Desk Monitor Arm sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the arm with a 10-year manufacturer warranty.
