Ergotron MX Desk Heavy Monitor Mount Polished Aluminum
PRODUCT DESCRIPTION
Ergotron MX Desk Monitor Arm Heavy Monitor Mount Polished Aluminum (45-214-026) - 10 Years Local Warranty
Built for Heavy Displays: 14 to 30 lbs (6.3 to 13.6 kg)
The Ergotron MX Desk Monitor Arm is the heavy-duty member of Ergotron's desk-arm range, engineered to move a display of 14 to 30 lbs (6.3 to 13.6 kg) and up to 30″ with fingertip pressure. That rating covers heavy professional panels, colour-critical production monitors and all-in-one computers that lighter arms simply cannot hold. Note that the 14 lb (6.3 kg) figure is a genuine minimum, not a formality — the counter-balanced lift needs the load to hold position, so light monitors belong on a different arm.
Constant Force Motion, No Tension Knobs
Patented Constant Force™ lift-and-pivot technology carries the weight for you: 5″ (13 cm) of lift, 80° of tilt (75° up, 5° down), a full 360° of pan and 90° of rotation between portrait and landscape, all moved with one hand and held exactly where you leave it. The display extends and retracts through 17″ (42 cm), so you can pull a heavy screen forward for detailed work and push it back when you need the desk.
Clamp or Grommet — Both Included
The box contains both mounting options. The desk clamp fits surfaces up to 2.6″ (66 mm) thick; the grommet mount passes through holes 0.31–2″ (8–51 mm) wide on desks up to 3″ (80 mm) thick. Between them they cover almost every desk in the Singapore market, from thin laminate benching to thick solid-timber executive tops, so you are not buying a separate mounting kit after the fact.
Reclaim the Desk, Tidy the Cables
A 30″ display's factory stand takes up a substantial share of a standard desk. Moving it onto the MX hands that surface back and puts the screen at a proper eye line rather than a fixed factory height. Cable management conceals and routes the display and power cables under the arm, keeping the work surface clear and making the desk easier to clean around.
Polished Aluminium, Backed 10 Years
The polished aluminium construction gives the rigidity a 13.6 kg display needs — no sag, no wobble on adjustment — with a finish that reads as professional equipment rather than office hardware. Ergotron backs the MX Desk Monitor Arm with a 10-year manufacturer warranty; SourceIT supplies it with local Singapore warranty and a GST invoice.

Compatibility & Fit
The Ergotron MX Desk Monitor Arm is rated for one display up to 30″ weighing 14 to 30 lbs (6.3 to 13.6 kg). The 14 lb (6.3 kg) minimum is as important as the maximum. The MX uses Constant Force™ lift, which is counter-balanced against the load: a display lighter than 6.3 kg will not hold position properly on it. If your monitor is under 6.3 kg, specify a lighter-duty arm such as the LX Desk Mount Monitor Arm or the NX Monitor Arm instead — SourceIT would rather steer you to the right arm than process a return.
Deep monitors: Ergotron notes that a monitor depth greater than 4″ (10.2 cm) may diminish the arm's capacity. Chunky all-in-one chassis and older heavy-housing panels should be checked with us first.
VESA fit: Ergotron states the MX Desk Arm fits most VESA-compliant monitors and HDTV displays; the install guide supplies brackets covering the common desktop and small-display patterns. Send SourceIT your monitor model and we will confirm the pattern against Ergotron's compatibility data before you order.
Mounting — clamp or grommet, both in the box: the desk clamp fits surfaces up to 2.6″ (66 mm) thick. The grommet mount fits holes 0.31–2″ (8–51 mm) wide through desks up to 3″ (80 mm) thick. Between them these cover almost every office and home desk in the Singapore market, including thicker solid-timber and reinforced benching tops.
Ultrawide and curved displays: the MX's ceiling is 30″ and its strength is weight, not width. A heavy 27″ or 30″ professional panel or all-in-one is its natural load. For 34″ and 38″ ultrawides look at the MXV Desk Monitor Arm or HX Desk Monitor Arm instead.
Number of screens: one. Ergotron does not offer a dual variant of the MX desk arm — for two displays see the MXV Desk Dual Monitor Arm or HX Dual Monitor Desk Arm.

Frequently Asked Questions — Ergotron MX Desk Monitor Arm
How heavy a monitor does the MX Desk Arm take — and is there a minimum?
Ergotron rates it 14 to 30 lbs (6.3 to 13.6 kg), and yes, the minimum is real. The Constant Force™ lift is counter-balanced against the load, so a display under 6.3 kg will not hold its height on this arm. Light monitors belong on the LX Desk Mount Monitor Arm or NX Monitor Arm instead.
What size screen does it support?
Up to 30″. Ergotron also notes that a monitor deeper than 4″ (10.2 cm) may reduce the arm's effective capacity, so deep all-in-one chassis should be checked before ordering.
Can I mount two monitors on it?
No — the MX Desk Arm is a single-display arm and Ergotron does not offer a dual version of it. For two screens, look at the MXV Desk Dual Monitor Arm (45-496-026) or the HX Dual Monitor Desk Arm (45-476-224).
Does it clamp or use a grommet, and what desk thickness does it fit?
Both are supplied in the box. The clamp fits desks up to 2.6″ (66 mm) thick; the grommet mount fits holes 0.31–2″ (8–51 mm) wide through desks up to 3″ (80 mm) thick. That covers virtually every office and home desk sold in Singapore, including thicker solid tops.
Will it fit my monitor's VESA pattern?
Ergotron states the MX fits most VESA-compliant monitors and HDTV displays, and supplies bracket hardware in the box. Monitors with no VESA pattern, or with a proprietary rear housing, may need the manufacturer's own adapter plate — send us your model and we will check.
Is it suitable for sit-stand working?
Only partly. The MX gives 5″ (13 cm) of lift, which is a seated adjustment range rather than a sit-stand one. Use it on top of a height-adjustable desk, or specify one of Ergotron's dedicated LX sit-stand desk arms if you need the screen to travel from seated to standing height on a fixed desk.
How does the MX Desk Arm compare with the MXV and LX desk arms?
The MX is the heavy-duty short-reach specialist: 30 lbs of capacity and 17″ of extension, with a 10-year warranty. The MXV Desk Monitor Arm (45-486-026) is the modern successor for larger, lighter panels up to 34″, and the LX Desk Mount Monitor Arm (45-241-026) is the general-purpose full-motion arm with more lift for lighter displays. If you need heavy capacity and a large screen, look at the HX Desk Monitor Arm.
Does the Ergotron MX Desk Monitor Arm come with a Singapore warranty?
Yes. Every Ergotron MX Desk Monitor Arm sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the MX Desk Monitor Arm with a 10-year manufacturer warranty.
