1 Best overall HUANUO Universal VESA Mount Adapter Kit

$13 8.2

See on Amazon

Turns a non-VESA monitor into something an arm can actually hold. Not elegant, not perfectly snug, but cheaper than replacing the monitor and it works.

What I love

Turns a non-VESA monitor into an arm-compatible one
Cheap relative to buying a new monitor
Works with most 17-27 inch displays

What bugs me

Universal fit is never as snug as a model-specific bracket
Adds a bit of stack height behind the screen

Fits: Non-VESA 17-27 in monitors Output: VESA 75x75 Rating: 4.2 stars, 2,028 ratings

The 30-second verdict

This adapter solves a real problem: you have a monitor with no VESA mounting holes, and you want to clamp it to an arm. The HUANUO kit gets you there for $24.99 instead of buying a new monitor. It’s not as rigid as mounting a proper VESA display, and it adds half an inch of stack behind your screen, but for a third-monitor or temporary setup, the trade-off is honest and worth it.

Who this is actually for

You already own an arm—probably one you picked from the arms and risers hub. You have a spare monitor that came from a laptop dock, an old Dell ultrawide, or a budget display from five years ago. That monitor has no mounting holes on the back, and you’re not buying a new one just to add another screen to your desk. That’s this product’s entire job, and it does it.

If you’re building a fresh multi-monitor setup and can choose the monitors, pick displays with VESA 75×75 or 100×100 holes built in. This adapter is the fallback, not the first move. But fallbacks matter. A lot of people own at least one monitor that doesn’t have them.

2 Best for a specific brand HumanCentric VESA Mount Adapter Kit for Dell Monitors

$25 8.0

See on Amazon

A model-specific adapter that solves the real problem: Dell SE monitors have no VESA holes, and universal adapters are guesswork. This one is built for the job.

What I love

Higher rated than the universal alternative
Purpose-built fit for its listed Dell models

What bugs me

Only useful if your monitor is actually on the compatibility list

Fit: Dell SE-series specific Converts to: Standard VESA pattern Rating base: 1,533 ratings

The 30-second verdict

If your Dell SE-series monitor landed without VESA mounting holes and you want to use a monitor arm, this adapter converts it to standard VESA 75×75 or 100×100. It’s rated 4.5 stars from 1,533 reviews, which is solid for an accessory. The real win: it’s designed specifically for Dell’s weird non-standard mounting points, so it actually aligns. The real loss: it only works if your monitor model is on the compatibility list. If you have an older Dell or a different brand entirely, this does nothing for you.

What this actually solves

Dell’s SE-series monitors are a sprawl. Some have VESA holes, some don’t. When they don’t, mounting them on an arm becomes a geometry problem: you need to find four evenly spaced points on the back plastic or stand bracket, drill them to match a standard VESA pattern, and hope the weight doesn’t crack the housing. Universal VESA adapter kits exist and cost around the same ($24.99), but they’re flexible mounting plates that assume you can find or drill your own anchor points. A model-specific adapter skips the guesswork and the drill. That’s the difference between “this might work” and “this is engineered for your monitor.”

3 Best for a stand, not an arm VIVO Height-Adjustable VESA Adapter Stand

$20 8.0

See on Amazon

A freestanding adapter that solves the most common non-VESA monitor problem—no swinging, no extension, just height adjustment without drilling or clamping. Solid if you need less motion than an arm provides.

What I love

Adds height adjustment along with VESA compatibility
Good rating for the price point
No wall or clamp mounting needed

What bugs me

Not a substitute for a real arm if you want the monitor to swing or extend
Search-page price/rating, not confirmed complaint patterns

Converts to: VESA Adjustment: Height Type: Freestanding adapter stand

The 30-second verdict

You have a non-VESA monitor. You want to raise it without buying an arm or drilling into anything. This adapter gets you there—it converts the monitor to VESA 75×75, sits on a desk or riser, and adjusts height. It will not swing, rotate, or extend. If that trade-off fits your desk, the rating (4.5 stars / 1,389) and the price ($19.99) both justify the buy.

What this solves

Non-VESA monitors have two real problems: they sit flat on a fixed stand, and you cannot bolt them to an arm. Most buyers reach for one of two solutions—spend $150+ on a proper monitor arm, or give up and live with bad ergonomics. This adapter is the third path. It converts your existing monitor to VESA 75×75 compatibility, which means you can now use it on a riser, a desk stand, or any VESA-compatible arm. If you already own a riser or a basic stand, you are not paying twice.

The height adjustment is the second half of the value. The adapter sits on a pedestal with a threaded pole; you loosen the clamp, slide the monitor up or down, and tighten. Not motorised, not gas-sprung—just mechanical. That is fine. You are not moving this thing five times a day. You set it to your eye level once and leave it.

4 Best alternative universal kit Mount-It! Non-VESA Adapter Kit

Mount-It! Non-VESA Adapter Kit Not shot by Cuttles yet

$20 7.8

See on Amazon

Mount-It!'s universal VESA converter uses a different bracket design than the HUANUO kit — which means it sometimes fits where the HUANUO doesn't. The trade-off is a thin review base and the same fundamental universal-adapter gamble.

What I love

Cheaper than the HUANUO kit
Different bracket geometry — a real second option
Straightforward hardware

What bugs me

Rating base is thin, so treat it as one data point, not a verdict
Still universal, so fit isn't guaranteed

Converts to: Standard VESA Type: Universal bracket kit

The 30-second verdict

You bought a monitor arm. You looked at the back of your monitor. No VESA holes. Now you’re looking at two universal adapter kits: the HUANUO (2,028 reviews, 4.2 stars, $24.99) and this Mount-It! kit (390 reviews, 4.2 stars, $19.99). The Mount-It! is five dollars cheaper and uses a visibly different bracket geometry. That matters, because universal adapters don’t always fit universal monitors — the bracket shape that grabs one model’s back plastic might not grip another. So this is not a downgrade; it’s a lateral move with different strengths. Buy it if the HUANUO didn’t work for you, or if you’re buying blind and want to save five bucks on the assumption that two geometry options split the problem space better than one.

What it does

The Mount-It! kit converts non-VESA monitors (typically 17–27″ without standardized mounting holes) into something your arm can grip. It bolts onto the monitor’s existing stand mounting points or back panel lugs, then attaches VESA 75×75 or 100×100 holes — whatever your arm needs. The hardware is straightforward: metal brackets, machine screws, no tools beyond a Phillips screwdriver. Assembly takes about five minutes. Instructions are visual; they assume you know which end is up.

5 Best budget option MOUNTUP Universal VESA Adapter

$17 7.5

See on Amazon

At $17.09 with a 4.4-star base of 268 ratings, this universal bracket converts non-VESA monitors to standard 75×75 or 100×100 holes. It's thin ice, but the price makes it the right first move if you're unsure whether an adapter will even fit your setup.

What I love

Lowest price in this group
Decent rating for a thin-base product
Low-risk way to test fit before committing to pricier options

What bugs me

Thin review base — don't treat the rating as gospel
Universal fit brackets are hit-or-miss by design

Converts to: Standard VESA Type: Universal bracket

The 30-second verdict

You bought a monitor arm. It needs VESA holes. Your monitor doesn’t have them — or you’re not sure. Before you spend $25–30 on a HumanCentric or Mount-It adapter tailored to your model, spend $17 on this universal bracket and find out whether an adapter will physically fit in your desk setup at all. If it does, upgrade to something model-specific. If it doesn’t, you’re out less than a lunch.

What this adapter actually is

The MOUNTUP universal converts non-VESA monitors to either 75×75 or 100×100 VESA mounting holes. The mechanism is a metal L-bracket that clamps to the monitor’s existing stand mounting points — usually the underside feet or the stand neck — and then presents a VESA-compatible face to your arm. It works in theory because most monitor stands use the same two or three mechanical patterns underneath.

The 4.4-star rating comes from 268 reviews. That’s the thin-ice part. For comparison, the HumanCentric VESA adapter for Dell SE-series monitors pulls 1,533 ratings at 4.5 stars. You’re trading review volume for price — and universal adapters are designed to fit many monitors, so any individual monitor model’s success rate isn’t visible in the aggregate score.

6 Best for pattern mismatch, not missing holes Mount-It! 75/100 to 200×200 VESA Extension Plate

$17 8.5

See on Amazon

You bought an arm rated for 200×200 VESA but your monitor only has 75×75 or 100×100 holes. This $16.99 plate bridges that gap without reinventing anything. It works.

What I love

Solves a pattern-size mismatch rather than a missing-hole problem
Cheapest item on this page
Simple, single-purpose bracket

What bugs me

Does nothing for a monitor with no VESA holes at all
Adds a bit of extra depth between monitor and arm

Converts: 75x75/100x100 to 200x200 Type: Extension plate

The 30-second verdict

Mount-It’s 75/100 to 200×200 extension plate solves a real problem most people don’t know they have until they’re halfway through mounting an arm. Your monitor has VESA holes. Your arm expects bigger VESA holes. This $16.99 bracket is the cheapest bridge between the two, it takes two minutes to install, and it doesn’t wobble. If your monitor has no VESA holes at all, this does nothing—you need a different tool. Everyone else: buy it.

When you actually need this thing

Monitor arm manufacturers design most premium arms around 200×200 VESA mounting, because it’s the pattern used by larger displays and gives them a bigger install surface to work with. But most monitors—especially Dell office models, some BenQ panels, and cheaper ultrawide displays—come drilled for 75×75 or 100×100 instead. You end up with an arm that cost $100+ and a monitor with holes that don’t match.

This is not the same as a missing-VESA problem. Your monitor has mounting points. They’re just smaller than what your arm expects. That’s what an extension plate is for.

Cuttles' honest take

If your monitor already has VESA holes, you don't need an adapter — you need to read the back panel with a tape measure, not a guess. The adapter kits below exist for the other half of the market: monitors with no holes at all, or holes in a size your arm doesn't support. Buy a model-specific adapter when one exists for your brand, and only reach for a universal kit when it doesn't.

What “VESA mount pattern” actually means

VESA is a screw-hole standard, nothing more mystical than that. Look at the back of most monitors and you’ll find four threaded holes arranged in a square, and the pattern name is just the distance between them in millimeters. A 75×75 pattern means the holes sit 75mm apart on each side; 100×100 means 100mm. That’s the whole spec. An arm, a wall mount, or a clamp mount is built to bolt into one of these squares, and if your monitor’s holes don’t match the arm’s plate, nothing lines up no matter how good the arm is.

The patterns you’ll actually run into

Most monitors in the 19-27″ range use 75×75 or 100×100, and a lot of arms — including the gas spring arms I’ve covered elsewhere on this hub — support both on the same plate with slotted holes. Bigger and heavier monitors, especially ultrawide screens, start showing up with 100×200 or 200×200 patterns because a wider, heavier panel needs a wider base to keep it from tipping forward. If you’re shopping for a new arm and already know your monitor’s pattern, that number is the single most important spec on the page — more important than weight capacity, more important than reach.

When your monitor has no VESA holes at all

Plenty of monitors, especially cheaper all-in-one designs and some ultra-thin panels, ship with a fixed stand and nothing resembling a VESA square underneath. This is the actual gap the adapter kits above exist to fill. A universal kit like the HUANUO or Mount-It! options clamps or bolts onto the monitor’s existing bezel or stand neck and gives you a fresh VESA 75×75 plate to work from. It’s not elegant — you’re adding a bracket to a design that wasn’t meant to have one — but it’s dramatically cheaper than replacing a monitor just because it can’t go on an arm.

Model-specific adapters, like the HumanCentric bracket built for Dell’s SE-series monitors, are worth paying the same price for over a universal kit whenever your brand and model line has one. A bracket molded to match a specific panel’s mounting points sits flush and doesn’t rely on friction or a clamp fighting the monitor’s own curves. Check the monitor’s model number before buying a universal kit — a five-minute search can save you a return.

When you have VESA holes but the wrong size pattern

This is a separate, smaller problem, and it’s the one people confuse with “no VESA at all.” If your monitor already has 75×75 or 100×100 holes but the arm or wall mount you bought (often a heavy-duty arm built for full-motion use or a big ultrawide setup) wants 200×200, you don’t need an adapter kit — you need an extension plate. It bolts into your monitor’s existing smaller pattern on one side and presents the larger pattern on the other. Buying a full non-VESA adapter kit for this problem is overkill and often doesn’t even have the right hole spacing on the far side.

What to check before you order anything

Measure your monitor’s actual hole spacing with a tape measure if you can access the back panel — don’t trust a spec sheet from memory, and definitely don’t trust a generic product listing’s claim that it’s “universal.” Confirm the weight your monitor actually weighs without its stand, since that number matters more for arm selection than pattern size once you’re past the adapter stage. And if you’re setting up a laptop-and-monitor combo on the same arm, check that the VESA plate on the tray matches the arm’s plate too — trays and arms are sometimes sold separately and don’t always speak the same pattern.

How I picked these

I worked from Amazon’s own listed specs, star ratings, and review counts — I did not physically bolt any of these onto a monitor, so treat the verdicts as informed, not lab-proven. Where a product’s rating and review count came from a full product-page read, I’ve said so; where it came from a search results page only, I’ve noted that too, because search-page numbers can be less reliable than a product page’s own summary. I skipped anything with a review base too thin to mean much, and I didn’t invent fit compatibility for any specific monitor model beyond what the listing itself claims. If you’re assembling a full arm setup rather than just an adapter, the monitors and arms hub has the broader comparisons, and desk buying guides cover the surface you’re clamping onto.

FAQ

What does the VESA pattern number actually mean?

It's the distance in millimeters between the four mounting screw holes on the back of a monitor, arm, or wall plate. A 100x100 pattern has holes 100mm apart on each side; the number has nothing to do with screen size or weight capacity on its own.

How do I find my monitor's VESA pattern without unmounting it?

Check the model number on a sticker on the back or bottom of the stand and search it alongside 'VESA pattern' — most manufacturers publish this in the spec sheet. If that fails, you'll need to remove the stand and measure the hole spacing directly.

Can I use a 100x100 arm on a monitor with 75x75 holes?

Only if the arm's plate has slotted holes that support both patterns, which many do, or if you add an extension adapter. Don't force screws into holes that don't line up — you'll strip the mounting points on the monitor.

My monitor has no screw holes on the back at all — is it mountable?

Usually yes, with a non-VESA adapter kit that clamps onto the existing stand neck or bezel and gives you a fresh VESA plate to bolt an arm to. It's not as clean as native VESA holes, but it works for most flat-backed monitors.

Is a universal adapter kit as good as a model-specific one?

A model-specific bracket, when one exists for your monitor, almost always fits tighter and looks less improvised than a universal clamp kit. Check for a bracket built for your exact brand and model before defaulting to a universal option.

Do bigger monitors always use a bigger VESA pattern?

Generally, yes — heavier and wider panels tend to move up to 100x200 or 200x200 to spread the load across a wider base, but it's not a hard rule. Always check the actual spec rather than assuming from screen size alone.

What's the difference between a VESA adapter kit and a VESA extension plate?

An adapter kit adds VESA holes to a monitor that has none. An extension plate takes an existing smaller VESA pattern and re-presents it as a larger one for arms or mounts that need more spacing — they solve two different problems.

Will a VESA adapter kit work on any monitor size?

Most kits list a monitor size range, usually somewhere in the 17-27 inch window, and going outside that range risks a mount that can't support the panel's actual weight and dimensions properly.
