Ergotron calls the LX Pro the next generation of its LX arm, and in Australia it is easy to buy from a first-party channel: on 5 November 2026 Amazon AU sold and shipped the black 45-682-292 clamp set at A$270.24, with other new offers from A$236.95 plus A$21.15 delivery from third-party sellers. The listing names the 13.5 cm pole version and states a ten-year manufacturer warranty that sits alongside Australian Consumer Law rights.
The decision turns less on the price than on the panel. Ergotron rates the Pro for 1.8 to 10 kg and screens up to 34 inches, a window that moved at both ends against the old LX's 3.2 to 11.3 kg. The sections below check that window, the desk the clamp needs, what the money buys over a gas-spring arm under A$40, and the variant traps on the listing.
Our verdict
Buy the LX Pro from Amazon AU itself if your monitor weighs 1.8 to 10 kg: A$270.24 buys Ergotron's ten-year warranty and a 33 cm lift that a A$38 gas-spring arm cannot match.
- A good fit for
- One VESA 75 or 100 monitor of 1.8-10 kg and up to 34 inches, on a desk 10-61 mm thick, used daily by someone who changes height often.
- We would skip it if
- Panels over 10 kg or without a VESA pattern, desks outside the clamp range, laptops without the separate tray, and 27-inch screens under 9 kg where a budget arm's shorter warranty is acceptable.
Reasons to consider it
- Amazon AU sells and ships it, and the listing states the ten-year manufacturer warranty sits on top of Australian Consumer Law rights
- Ergotron prints 33 cm of lift, 85 degrees of tilt (70 back, 15 forward) and a 10,000-cycle lift test for the Pro
- The listing's model number 45-682-292 and UPC match the part Ergotron documents, with a 13.5 cm pole
The compromises
- The 1.8-10 kg window drops the heaviest panels the old LX carried (up to 11.3 kg)
- No grommet hardware in the box: a grommet install needs the separate 98-728-292 base
- Budget arms on the same day started near A$38 for 2-9 kg panels and 32-inch screens, a fraction of the price
What we have not verified: Every motion figure is Ergotron's own claim, and no source checked shows how the spring holds a near-10 kg panel after years of daily use. The Australian Ergotron page did not render its product block when opened, so the specifications come from the US spec sheet and the Amazon AU listing.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
LX Pro Monitor Arm (single, 5 in pole)
A$270.24 from Amazon AU on 5 November 2026 buys 33 cm of lift, 85 degrees of tilt, 360-degree pan and rotation, a 63.5 cm reach, VESA 75 and 100 support for screens up to 34 inches, and a ten-year warranty.
Before you buy: Capacity stops at 10 kg and panels deeper than 9.1 cm can lose rating; the clamp needs a desk 10-61 mm thick, grommet holes need the separate 98-728-292 base and laptops the 50-193-200 tray.
Price checked 5 November 2026. Retailer prices can change.The Pro replaces the LX; it is not a cheaper version
Ergotron's own LX page carries the handover in print: a "New Version Available" banner pointing to the LX Pro and the line that the old SKU is phasing out with limited availability. Amazon Australia still lists the old LX single arm in polished aluminium at A$270.00, the same money as the Pro, so the only reason to pick it is the heavier capacity covered below.
Most of the arm carries over: 33 cm of lift, VESA 75 and 100 plates, a ten-year warranty and Ergotron's 10,000-cycle lift test. What moved is the envelope. Capacity went from 3.2-11.3 kg to 1.8-10 kg, and total tilt from 75 degrees (70 back, 5 forward) to 85 (70 back, 15 forward), which helps square a screen mounted above eye level at a standing desk.
Weigh the monitor before anything else
Ergotron rates the Pro for screens up to 34 inches and 1.8 to 10 kg, with two printed conditions: a display deeper than about 9.1 cm may reduce capacity, and the 34-inch figure is approximate as long as the weight stays inside the window. The lower floor is the real change: light panels from 1.8 kg now balance, where the old LX started at 3.2 kg. The VESA 75 or 100 pattern is the other gate, and laptops need Ergotron's 50-193-200 tray.
The ceiling is where owners of heavy ultrawides should check the spec sheet of their monitor without its stand. A panel between 10 and 11.3 kg fitted the old LX and does not fit the Pro, though the old page printed its own penalty above about 9 kg: lift could shrink by up to 11 cm, to around 22 cm in total. Over 10 kg, this arm is out of spec at any price.
What the arm does, and what your desk must offer
Ergotron's figures for the Pro: a constant-force spring with a tension indicator, 33 cm of lift that raises the screen to about 46.5 cm above the desk on the 13.5 cm pole, 70 degrees of tilt back and 15 forward, 360 degrees of pan and rotation with a stop that can limit the swing to 180, and up to 63.5 cm of reach. The arm weighs about 3.8 kg.
Three measurements settle the desk. The two-piece clamp fits tops 10 to 61 mm thick and needs up to about 71 mm of clear space underneath, so a crossbar or drawer under the edge can rule it out. A grommet hole needs the separate 98-728-292 base, which Amazon AU lists as its own product. Ergotron also offers a 30 cm high-column version (45-695), which Amazon AU listed at A$293.65.
What A$270 buys over a A$38 gas-spring arm
The VESA plate is not the difference: budget arms use the same 75 and 100 patterns. Amazon Australia's results on 5 November showed the HUANUO FlowLift at A$37.99 for 13-32 inch screens and 2-9 kg, the MOUNTUP desk mount at A$37.99 for screens up to 32 inches, and North Bayou's F80 at A$51.40 for 2-9 kg. Against them, the Pro pays out at the edges: 34 inches instead of 32, 10 kg instead of 9, and a ten-year warranty.
Spread over Ergotron's ten years, A$270.24 is about A$27 per covered year, and the gap to the FlowLift is A$232.25. That money buys the higher ceilings, the longer cover and Ergotron's published lift test; the hole pattern comes with both. For a 27-inch monitor under 9 kg on a desk you may replace in a few years, the budget arm does the same job.
Who sells it, and the variant traps
Buy from the Amazon AU offer rather than the cheaper third-party ones: the A$236.95 offers add A$21.15 delivery, which leaves A$258.10 against A$270.24, and a direct purchase keeps returns and faulty-item claims with Amazon AU. The listing's model number, 45-682-292, and UPC match the part Ergotron documents for the black clamp set.
The traps sit in the search results. Several LX Pro listings appear at A$240 to A$268, alongside the high-column 45-695 and the old LX single arm, so check the part number on the product page before you trust any specification shown next to it. Prices for each listing move independently.
