A 42-inch display on its factory stand eats the whole desk, which is why the best monitor arm for lg c2 42 is worth sorting out before buying. This guide compares four monitor arm listings on stated screen size, weight capacity, motion, mounting and warranty, with every figure taken from the listings. The honest headline: only one listing states a screen range that covers 42 inches, so check each pick’s stated numbers against the display before anything else.
The listings state their case in two numbers first: the screen-size range and the weight capacity. After that come the motion range, the mount hardware and the warranty. The table below lines up the stated figures, and the buying advice walks through each one.

Detailed Review
The listing states a single monitor arm for 13 to 38 in flat, curved or ultrawide screens weighing 9.5 to 30.8 lbs, with VESA 75x75mm or 100x100mm mounting holes. The gas spring is set around 26 lbs, height adjusts from 6.6 to 18.8 in, and the listing cites a 10,000-cycle motion rating. The heavy-duty metal base covers 4.6 x 4 in of desk, and the C-clamp supports desks up to 2.3 in thick. The spec table states a 3 Year Warranty. No contradiction between the title, bullets and spec table.
Who it's for: a buyer who wants the widest stated screen range with a stated warranty. Who should skip it: anyone whose desk is thicker than 2.3 in, since the C-clamp tops out there.
Its Office Score of 9.7/10 comes from performance 30/35, build 21/25, value 21/25, safety 7/10 and warranty 4/5: 83 of 100 points, placed on our 9.2 to 9.8 scale.

Detailed Review
The listing states a single monitor arm for 13 to 36 in screens at 22 lbs, with VESA 75x75 and 100x100mm patterns, -35 to 90 degree tilt, 180 degree swivel and 360 degree rotation.

One contradiction: the title and bullets say 13 to 36 in while the spec table lists 17 in minimum and 32 in maximum; trust the title and bullets.
Who it's for: a buyer who wants the widest stated motion range. Who should skip it: anyone who needs a stated warranty, since this listing states none.

How we scored them
The Office Score weighs performance, build, value, safety and warranty. For monitor arms, safety means the stated weight capacity and the mount hardware that holds the screen: both full listings state capacities and C-clamp or grommet mounting. One of the four states a warranty with a concrete term, the AVLT with its 3 Year Warranty; the rest state none. How we pick explains the weights.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| AVLT Single Monitor Arm | 9.7 | 30 | 21 | 21 | 7 | 4 |
| ErGear Single Monitor Arm | 9.6 | 30 | 21 | 21 | 7 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best monitor arm for lg c2 42
Screen size: the 42-inch question
Stated screen ranges decide this guide. The AVLT states 13 to 38 in, the ErGear states 13 to 36 in, and only the WALI states 13 to 43 in, which covers a 42 in display. The VIVO states no screen size. Neither full listing states 42 in support, so a 42 in buyer should treat the WALI as the only pick whose listing claims the size, and verify weight and VESA pattern separately. The WALI is also a dual-arm design, so it holds two screens where the others hold one, and its 24.5 in reach is the longest stated reach of the set. For ultrawide-specific arms, see best monitor arm for ultrawide.
Weight capacity and gas springs
Stated capacities run from 22 lb on the ErGear to 9.5 to 30.8 lb on the AVLT, whose gas spring is preset around 26 lb, up to 33 lb per arm on the WALI. Match the capacity to the display: a spring set far above or below the screen weight will not hold position well, which is why the AVLT listing flags its 26 lb preset. Cycle ratings are stated too: a 20,000+ cycle endurance rating on the ErGear and a 10,000-cycle motion rating on the AVLT. The ErGear listing also claims its arm is 3x stronger than standard arms to eliminate sagging and wobble, and up to 80% more workspace than bulky monitor stands; those are maker claims, not measured figures.
Mounting, reach and motion
Both full listings offer C-clamp or grommet mounting. The ErGear clamp fits desks 0.39 to 2.76 in thick and the grommet 0.39 to 2.17 in; the AVLT clamp fits desks up to 2.3 in thick on a 4.6 x 4 in base. Height adjustment runs 6.6 to 18.8 in on the AVLT; the ErGear reaches 17.5 in vertically and 15.3 in horizontally. Motion is widest on the ErGear at -35 to 90 degree tilt, 180 degree swivel and 360 degree rotation. Measure the desk thickness before ordering, since the clamp range is the hard limit. Both full listings include cable management: integrated cable clips on the ErGear and a cable-hiding design on the AVLT. The ErGear ships with instructions and a standard hardware kit, and the AVLT listing says assembly takes less than 5 minutes with its top mounting design.
One more ErGear option
An extra ErGear listing fits this topic but is not ranked above. It states a single arm for 13 to 34 in screens at 19.8 lb, with VESA 75x75mm or 100x100mm patterns, a 20,000+ cycle rating, 17.5 in of height adjustment and 18.1 in of reach. Tilt is +80 to -50 degrees with ±90 degree swivel and 360 degree rotation, and mounting covers C-clamp for desks 0.39 to 2.56 in or grommet for 0.39 to 2.95 in. The spec table states a 2-year warranty, which makes it the only other warrantied pick in this set. The listing also claims a 40 percent wider VESA head for stability, tool-free VESA mounting, and setup in three steps with cable clips that open without tools.

Frequently Asked Questions
Will these arms hold a 42 inch display?
Only the WALI states a screen range covering 42 in, at 13 to 43 in. The AVLT states 13 to 38 in and the ErGear states 13 to 36 in. Check the listing’s stated range before buying. The VIVO states no screen size at all, so it cannot be checked against a 42 in display from its listing.
What weight can these arms hold?
The AVLT states 9.5 to 30.8 lb with its gas spring preset around 26 lb, the ErGear states 22 lb, and the WALI states 33 lb per arm. The extra ErGear states 19.8 lb.
Do any of these listings state a warranty?
The AVLT states a 3 Year Warranty and the extra ErGear states a 2-year warranty. The other listings state no warranty term. The WALI and VIVO listings are titles only, so no warranty could be stated there.
What desk thickness do the clamps fit?
The ErGear C-clamp fits desks 0.39 to 2.76 in thick, the AVLT clamp fits up to 2.3 in, and the extra ErGear clamp fits 0.39 to 2.56 in. Measure the desk before ordering. Grommet mounting is also stated on both ErGear listings for desks 0.39 to 2.17 in and 0.39 to 2.95 in thick.
