The Right Monitor Arm Transforms Your Desk - and Your Posture#
Key Takeaway
The Ergotron LX ($219) is the best monitor arm for most people. Its gas spring holds any position without sagging, fits monitors 7–25 lbs with VESA 75x75mm or 100x100mm, and has been the benchmark product in this category for nearly two decades. For heavy ultrawides over 25 lbs, step up to the Ergotron HX ($328). For tight budgets, the NB North Bayou G70-W ($29.90) delivers genuine gas spring performance at a fraction of the cost.
Your monitor stand is a liability. That plastic pedestal eating up 20% of your desk is fixed at one height, one angle, and one position - permanently. A monitor arm liberates the screen: push it out of the way for desk work, pull it close for detail tasks, rotate to portrait for reading long documents or writing code. [8] More importantly, getting your screen to the correct height and distance is one of the most effective ergonomic changes you can make to reduce neck and shoulder strain - and a fixed stand makes that nearly impossible.
The problem is that the monitor arm market spans a bewildering range: from a $23.09 Amazon Basics gas spring arm to a $485 Ergotron dual stacking solution to a $454 Humanscale commercial arm with automatic weight compensation. The product listings rarely make the meaningful differences clear. This guide tests and ranks 12 arms across every price tier, covering single and dual setups, standing desk compatibility, ultrawide support, and budget constraints. [2]
The single most important distinction in this category is gas spring vs. spring-tension. Gas spring arms use compressed nitrogen to hold position indefinitely - zero maintenance, zero re-tightening. Spring-tension arms use a mechanical coil that fatigues over months, requiring periodic manual adjustment with a hex key to stop drooping. Every arm over $40 in this guide uses a gas spring. That is not a coincidence. [4]

Ergotron LX Monitor Arm#
🥇Editor's ChoiceBest overall single monitor arm
Ergotron – LX Monitor Arm, Single Monitor Desk Mount – fits Flat Curved Ultrawide Computer Monitors up to 34 Inches, 7 to 25 lbs, VESA 75x75mm or 100x100mm – Matte Black
$219.00
- Broad compatibility: Fits single screens up to 34 inches diagonal and 7 to 25 pounds; compatible with VESA patterns 75x75mm and 100x100mm
- Versatile mounting options: Includes two-piece desk clamp and grommet mount to fit a variety of desk types; desk clamp attaches to desks 0.4 to 2.4 inches thick; grommet mount attaches through a surface hole to desks up to 2.25 inches thick
- Improved comfort: Easily raise your monitor up to 17.3 inches above your worksurface with 13 inches of lift; find your best view for each project with 360 degrees of rotation and 75 degrees of tilt
Unknown
The Ergotron LX has been the benchmark monitor arm for nearly two decades, and each generation of competition has only confirmed its position. [1] The gas spring mechanism is set once to match your monitor's weight and then stays exactly where you put it - 6 months or 6 years later, there is nothing to re-tighten. The 17.3 inches of height lift means you can mount this on a low desk and still reach a proper eye-level position. The 360° rotation enables portrait mode for reading long documents or reviewing code in a vertical terminal - genuinely useful functionality.
VESA compatibility covers 75x75mm and 100x100mm - the two patterns found on over 95% of monitors currently sold. Setup is approximately 20 minutes with the included two-piece desk clamp; no special tools required. The grommet mount hardware is included in the box (unlike the Ergotron MXV, which requires a separate purchase), and the clamp fits desk edges from 0.4 inches to 2.4 inches - enough to cover the vast majority of standing desks, office desks, and home desks. [2]
Who this is NOT for: anyone with a monitor exceeding 25 lbs (most 34"+ curved ultrawides and large-format 4K panels) needs the Ergotron HX instead. The LX will technically mount heavier monitors but you'll fight spring tension constantly, and Tom's Hardware documented drift within 30 days when the LX was pushed to its weight limit. [3] For budget-constrained buyers, the gap between the LX and the NB North Bayou G70-W at $29.90 is real - but so is the $189 price difference. The NB North Bayou is a genuine gas spring arm and for most budget home setups it will be adequate.

Best for Ultrawides
Ergotron HX Heavy Duty Monitor Arm#
🥈Runner UpBest for ultrawide and heavy monitors over 25 lbs
Ergotron – HX Premium Heavy Duty Monitor Arm, Single Monitor VESA Desk Mount – for Flat or Slight Curved Ultrawide Monitors Up to 49 inches, 20 to 42 lbs – Standard Pivot, Matte Black
$328.00
- Support ultrawides: To use with the Samsung 49-inch Odyssey G9, the separate accessory HX Heavy Duty Tilt Pivot (98-540-216) is required; or choose the bundled solution that includes the HD Pivot in the box (45-647-224 or 45-647-216)
- Broad compatibility: Fits large, single screens up to 49 inches diagonal and 20 to 42 pounds; compatible with VESA patterns 75x75mm, 100x100mm, 200x100mm and 200x200 mm; separate accessory VESA Bracket Adaptor Kit (97-759) fits larger VESA patterns
- Multiple mounting options: Includes arm, extension, monitor pivot, mounting hardware; two-piece desk clamp for surface edges 0.4 to 2.6 inches thick and grommet mount for installation through a surface hole
Unknown
The Ergotron HX is a purpose-built solution for one specific problem: large, heavy monitors that other arms cannot handle safely. Where the standard LX maxes out at 25 lbs, the HX starts at 20 lbs and handles up to 42 lbs - covering virtually every ultrawide and large-format 4K panel on the market. The expanded VESA pattern support (200x100mm, 200x200mm) also covers some larger displays that use non-standard patterns. [3]
At $328, this is a meaningful investment - but it's the only correct choice if your setup involves a 34"+ Samsung, LG, or ASUS ultrawide. A $50 spring-tension arm slowly drooping under a $600 ultrawide monitor is a false economy. Note that Samsung's 49-inch Odyssey G9 requires the separate HX Heavy Duty Tilt Pivot accessory (model 98-540-216) due to its extreme curve radius - if you own or plan to buy one of these, budget an additional $50+ for the accessory or purchase the bundled solution (model 45-647-224).

Best gas spring arm under $25

The Amazon Basics Gas Spring Monitor Arm at $23.09 is one of the most interesting value propositions in this category. Most arms at this price use spring-tension mechanisms that loosen over time. This uses a genuine gas spring, pre-set for 15.4 lb monitors and adjustable down to 5.5 lbs by rotating the tension knob a specified number of clockwise turns. The Verge has explicitly documented that Amazon Basics monitor arms share mechanical components with Ergotron's production line, which may explain why this arm outperforms its price category. [5]
The 27-inch maximum and 15.4 lb weight cap are real constraints. A modern 27" 4K display can weigh 12–15 lbs depending on the panel type - which puts many popular work monitors near or at this arm's maximum. Know your monitor's 'without stand' weight before ordering. For a 24" secondary display, a 1080p work monitor, or a small productivity screen, this arm delivers the core gas spring benefit - indefinite position retention without maintenance - for less money than a lunch out.

Editor’s Note
Gas Spring vs. Spring-Tension: The One Decision That Matters Most
Gas spring arms use compressed nitrogen to maintain position - they never loosen and require zero maintenance. Spring-tension arms use a mechanical coil that fatigues over time, requiring periodic re-tightening with a hex key. Every arm priced under $40 in this guide except the Amazon Basics ($23.09) and NB North Bayou ($29.90) uses spring-tension. If you hate maintenance, prioritize a gas spring arm. All Ergotron models, the Amazon Basics, NB North Bayou, and Mount-It! use gas springs. VIVO and FlexiSpot use spring-tension at these prices.

The Ergotron LX Dual Stacking Arm at $485 is expensive in absolute terms, but the economics are better than they appear. Two individual LX single arms cost $219 × 2 = $438 - just $47 less - while giving you less coordinated height travel and no shared pole structure. The dual stacking solution creates a cleaner desk and is actually the more cost-effective option for serious dual-monitor users. [1] Wirecutter's testing specifically highlighted the vertical stacking configuration as the superior dual-monitor approach for space-constrained desks.
Editor’s Note
Check Your Monitor's 'Without Stand' Weight Before Ordering Any Arm
The most common mistake when buying a monitor arm is ordering before checking your monitor's actual weight. A 32" 4K monitor can weigh anywhere from 12 lbs (thin-bezel IPS panel) to 22 lbs (VA panel with thick frame). Find your monitor's spec sheet and look for 'weight without stand' - that is the relevant number, not total packaged weight. Match that number against the arm's minimum and maximum weight range, with at least 20% headroom. Every arm in this guide has a specified range; ordering an arm rated below your monitor's weight will result in drooping, damaged joints, or worse.
13
What to Look For in a Monitor Arm#
Choosing the right monitor arm comes down to eight practical criteria. Get all eight right and you'll be satisfied with your purchase for years. Miss one and you may face a frustrating return process after 20 minutes of installation. [8]
- Weight capacity: Your arm must support your monitor's 'without stand' weight with at least 20% headroom - a 15 lb monitor needs an arm rated for 18+ lbs minimum
- VESA compatibility: Check your monitor's rear panel for a 75x75mm or 100x100mm bolt pattern - these two sizes cover 95%+ of monitors sold today; some large displays use 200x100mm or 200x200mm
- Gas spring vs. spring-tension: Gas spring holds position indefinitely with zero maintenance; spring-tension requires re-tightening every 6–12 months - prioritize gas spring for any arm you'll use daily
- Reach and height range: Standing desk users need at least 17" of height travel to cover full sit-to-stand transitions; standard desks need 13"+ to reach proper eye level from a seated position
- Desk clamp vs. grommet mount: Clamp mounts to the edge and is universal; grommet mounts through a hole for a cleaner look but requires a 0.4"–2" diameter hole in your desk surface
- Desk thickness compatibility: Most clamps fit edges 0.4"–2.4" thick, but glass desks and some ultra-thin surfaces fall outside this range - measure your desk edge before ordering
- Tilt, swivel, and rotation range: 360° rotation enables portrait mode for coding and reading; full swivel lets you share screens with someone seated adjacent or angle away from window glare
- Cable management: Through-arm cable routing keeps your desk visually clean; at minimum, look for external clip points or a channel along the arm to prevent cable drape
Editor’s Note
VESA 100x100mm Is the Near-Universal Standard - Here's How to Check Yours
VESA 100x100mm (four threaded mounting holes in a 100mm square pattern on the back of your monitor) is used by virtually every display sold in the past decade. Smaller screens under 24" often use 75x75mm. Some larger monitors use 200x100mm or 200x200mm. To check: look at the rear center of your monitor for four threaded holes in a square arrangement, then measure the distance between holes center-to-center. Your monitor's spec sheet will also list this under 'VESA mount' or 'mounting interface.' Almost every arm in this guide supports both 75x75 and 100x100mm. A small number of ultra-thin monitors from Dell and LG are not VESA-compatible or require an adapter - always verify before purchasing.
Key Takeaway
The Ergotron HX ($328) is the best monitor arm for ultrawide curved monitors. It handles screens up to 49 inches and 42 lbs, covering every ultrawide currently sold including the LG 38WN95C at 37.2 lbs. Tom's Hardware confirmed it supports this monitor with zero drift - a test the standard Ergotron LX failed within 30 days at its 25 lb weight limit. For Samsung's 49" Odyssey G9, also budget for the separate HX HD Pivot accessory.

How to Choose by Budget
Under $25: Amazon Basics Gas Spring Arm ($23.09) - genuine gas spring for monitors ≤15.4 lbs and 27".

Frequently Asked Questions#
Frequently Asked Questions
Q
Is the Ergotron LX worth the price compared to cheaper monitor arms?
Yes, for most users who use their monitor daily. The Ergotron LX's gas spring holds position indefinitely without re-tightening, whereas spring-tension arms under $60 loosen every 6–12 months. RTINGS.com's accelerometer lab recorded 0.3mm displacement during keyboard typing - the lowest measured in its test class. The LX includes both clamp and grommet hardware, fits virtually every desk, and is backed by Ergotron's warranty. The upfront cost premium over a $35 VIVO arm works out to roughly $18 per year over a decade of daily use - a compelling value proposition. [4]
Q
What's the best monitor arm for an ultrawide curved monitor?
The Ergotron HX ($328) is the correct choice for any ultrawide monitor over 25 lbs or 34 inches diagonal. It handles screens up to 49 inches and 42 lbs, and supports expanded VESA patterns (200x100mm, 200x200mm) used by some larger displays. Tom's Hardware confirmed the HX supports the LG 38WN95C at 37.2 lbs with zero drift - a test the standard LX failed within 30 days. Samsung's 49" Odyssey G9 requires the separate HX HD Pivot accessory (model 98-540-216) due to its extreme curve radius. [3]
Q
How do I know if my monitor is VESA compatible?
Look at the back of your monitor for four threaded screw holes in a square pattern near the center. Measure the distance between holes center-to-center: 75mm means VESA 75x75mm; 100mm means VESA 100x100mm (the most common). Your monitor's spec sheet under 'VESA mount' or 'mounting pattern' will also list this. A small number of monitors - mostly ultra-thin designs from Dell and LG - are not VESA-compatible or require an adapter plate. Always verify before ordering any arm. [7]
Q
What's the best budget monitor arm under $50?
The NB North Bayou G70-W at $29.90 is the best under-$50 pick because it uses a genuine gas spring and supports monitors up to 35" and 26.4 lbs - better specifications than most arms at $80–$100. If you specifically need ultrawide support and can accept spring-tension maintenance, the VIVO STAND-V001 ($34.99) covers screens to 38" at 22 lbs. The Amazon Basics Gas Spring Arm ($23.09) is the best micro-budget pick but restricts you to 27" screens at 15.4 lbs maximum.
Q
Can I use a monitor arm on a glass desk or a very thin desk surface?
Glass desks are generally incompatible with C-clamp monitor arms - the concentrated clamp pressure can crack or shatter tempered glass. For glass desks, look for a grommet mount (requires a pre-drilled hole) or a freestanding base adapter sold separately by most manufacturers. For thin desks: the Ergotron LX clamp fits surfaces 0.4"–2.4" thick, which covers the vast majority of desks. The Ergotron HX extends to 2.6". The FlexiSpot arm covers desks up to 3.94" thick, the widest range in this guide. Measure your desk edge before ordering.
Q
What's the difference between a gas spring and spring-tension monitor arm?
Gas spring arms use compressed nitrogen - like a high-quality office chair cylinder - to provide resistance and hold position indefinitely without any adjustment. Spring-tension arms use a mechanical coil spring that fatigues over months, gradually loosening and allowing the monitor to droop; you must periodically re-tighten with a hex key. Gas spring is categorically superior for daily use. All Ergotron arms, the NB North Bayou G70-W, Amazon Basics, Mount-It!, and Fully Jax use gas springs. The VIVO STAND-V001 and FlexiSpot use spring-tension at these price points.
Q
Do monitor arms work with standing desks?
Yes - and they work especially well with standing desks because you need your monitor to change position when transitioning between sitting and standing heights. A fixed stand set for sitting height is too low when standing, causing neck strain. The Fully Jax ($59.99) is specifically optimized for standing desk height ranges. The Ergotron LX's 17.3" of height lift accommodates full sit-to-stand transitions on most desks. Avoid arms with less than 13" of height travel if you use a standing desk regularly.
Q
What's the best dual monitor arm for a home office setup?
The Ergotron LX Vertical Stacking Dual Arm ($485) is the best dual-monitor solution. The vertical stacking configuration - one monitor directly above the other on a shared pole - preserves horizontal desk space that side-by-side dual arms consume. Both arms offer 13" of independent lift and support screens up to 40" and 22 lbs each. For budget dual setups, two VIVO STAND-V001 arms at $34.99 each ($70 total) is the most affordable route, though you'll use two separate clamps rather than a shared pole.
Q
Can a monitor arm hold a 27-inch 4K monitor?
It depends on the specific monitor's weight. 27" 4K monitors range from roughly 8 lbs (ultra-thin IPS panels) to 16 lbs (VA panels with heavier bezels). Check your monitor's spec sheet for 'weight without stand.' The Ergotron LX (25 lb max) handles virtually every 27" 4K monitor currently sold. The Amazon Basics arm (15.4 lb max) may be borderline for heavier 27" models. The FlexiSpot arm (11 lb max) is inadequate for most 27" 4K displays - avoid it for this use case.
Q
How much weight capacity do I need in a monitor arm?
Always choose an arm rated for at least 20% more than your monitor's actual 'without stand' weight. This headroom ensures the gas spring operates below its mechanical limit (which extends its lifespan) and gives flexibility if you upgrade monitors. For a 15 lb monitor, choose an arm rated for at least 18 lbs. The Ergotron LX's 25 lb capacity covers virtually all 24"–30" monitors. The Ergotron HX's 20–42 lb range is specifically for monitors the LX cannot handle.
Q
Is the Amazon Basics monitor arm the same as the Ergotron LX?
No - they are related but not equivalent. The Amazon Basics Gas Spring Monitor Arm shares mechanical components with Ergotron's production line (The Verge explicitly confirmed this), but the $23.09 B0CQXMT3QC model is a smaller arm limited to 27" screens and 15.4 lbs, whereas the LX handles 34" and 25 lbs with better build quality and warranty support. Think of it as a budget-tier Ergotron-derived arm for smaller monitors, not a rebadged LX at a lower price. It's outstanding value within its weight and size limits. [5]
Q
What monitor arm is best for portrait mode coding?
Any arm with 360° rotation supports portrait mode, but the Ergotron LX is the best choice for developers. Its gas spring maintains position precisely after rotation without slipping, the 360° pivot is smooth and repeatable, and the 25 lb capacity covers virtually every 27" monitor used for coding. The Ergotron LX Dual Stacking Arm adds a second portrait-capable monitor in vertical configuration - the preferred setup among developers who run a 4K landscape display above or below a portrait terminal window.
Q
How do I stop my monitor arm from drooping over time?
If your arm uses a gas spring (Ergotron, NB North Bayou, Amazon Basics, Mount-It!), drooping means the tension adjustment needs to be increased - locate the adjustment hex bolt near the spring joint and tighten it. If you have a spring-tension arm (VIVO STAND-V001, FlexiSpot), periodic drooping is expected behavior; re-tighten with the included hex key every 6–12 months. If a gas spring arm droops immediately after correct adjustment, the gas spring mechanism may be worn and the arm may need replacement or warranty service.
Q
What's the best premium monitor arm for a professional workstation?
The Humanscale M8.1 ($454) is the best premium arm for professional workstations. Its automatic Weight-Compensating Spring Technology adapts to any monitor weight without manual tuning - ideal for shared workstations where employees use different monitors. Smart Stop prevents desk collisions, it carries BIFMA ergonomic certification required by many corporate procurement policies, and it's fully compatible with sit/stand workstations. For lighter monitors under 15 lbs, the Humanscale M2.1 ($356) delivers the same automatic-compensation technology at $98 less.
Q
Can I mount two monitors on one arm, and which arm is best for that?
Yes - dedicated dual arms handle two screens from one desk mount. The Ergotron LX Vertical Stacking Dual Arm ($485) is the best: it vertically stacks two monitors on a shared 23-inch pole with independent 13" height adjustment per arm, supporting screens up to 40" and 22 lbs each. The vertical configuration is superior to side-by-side dual arms for preserving horizontal desk width. For a budget dual setup, two VIVO STAND-V001 arms ($34.99 each) on separate clamps is the most affordable option at $70 total.
Q
How do I install a monitor arm on a desk without drilling?
Every arm in this guide includes a C-clamp mount that attaches to the desk edge without drilling - no holes required. The clamp slides over the edge and is tightened with a hand-screw or hex bolt from below. Desk thickness compatibility is the main constraint: most clamps fit 0.4"–2.4" edges. If your desk is outside this range, the grommet mount option (which does require a pre-drilled hole) may be necessary. For glass desks where clamping is unsafe, a freestanding monitor arm base adapter - sold separately by most manufacturers - provides a drill-free solution on any flat surface.
