Best Monitor Arm for LG UltraGear
LG UltraGear monitors are absolute beasts for gaming and color-accurate editing, but let’s be honest: their stock V-shaped stands are massive desk hogs. To truly unlock your setup’s potential and clear some room for your mousepad or audio interface, a high-quality monitor arm is essential. I’ve tested dozens of mounts, and for most UltraGear owners, the Ergotron LX stands out as the gold standard for its fluid movement and rock-solid stability. Here are my top recommendations.

Best Monitor Arm for LG UltraGear: Detailed Reviews
Ergotron LX Single Monitor Arm View on Amazon View on B&H
The Ergotron LX is the undisputed heavyweight champion in the monitor arm world. If you’ve invested in a high-end LG UltraGear like the 27GP850-B, you want an arm that feels just as premium. Using their proprietary Constant Force technology, the LX allows you to move your monitor with a literal fingertip. It doesn’t just “hold” the monitor; it makes it feel weightless. It supports up to 25 lbs, which easily covers most UltraGear displays. During my testing, I found the polished aluminum finish to be incredibly durable, resisting scratches even after multiple adjustments. One minor drawback is the price—it’s an investment—but considering it comes with a 10-year warranty, it’s likely the last monitor arm you’ll ever need to buy. It fits the recessed VESA mount on the back of LG panels perfectly without needing extra spacers, which is a huge plus for a clean install.

HUANUO Gas Spring Monitor Mount View on Amazon View on B&H
The HUANUO Gas Spring mount is the perfect middle ground for gamers who want the functionality of a premium arm without the three-figure price tag. It handles monitors up to 32 inches and 19.8 lbs, making it a great match for the popular LG UltraGear 32GP850. I was pleasantly surprised by how smooth the gas spring tensioner is; once dialed in, it holds the height perfectly without drifting. The cable management system is functional, though a bit more plastic-heavy than the Ergotron. You get both C-clamp and grommet mounting options in the box, which is great for versatility. While it doesn’t feel quite as “industrial-grade” as the top pick, it provides a significantly better experience than basic mechanical arms. It’s an excellent value proposition for those who want to reclaim their desk space and achieve better ergonomics on a sensible budget.

VIVO Single Monitor Desk Mount View on Amazon View on B&H
If you don’t plan on constantly moving your monitor around and just want to get that bulky LG stand out of the way, the VIVO Single Monitor Mount is an absolute steal. Unlike gas spring arms, this is a mechanical pole-and-clamp system. You set the height once, tighten the bolts, and it stays there. It’s incredibly sturdy because there are fewer moving parts to wear out. The main limitation is the lack of “on-the-fly” height adjustment; you’ll need an Allen key if you want to change the vertical position later. However, for a set-it-and-forget-it UltraGear gaming station, it’s flawless. It supports up to 22 lbs, so it handles the 27″ and 32″ LG models with ease. The footprint on the desk is tiny, which is exactly what we’re looking for. It’s honest, no-frills hardware that gets the job done for the price of a few pizzas.

Ergotron HX Single Monitor Arm View on Amazon View on B&H
Own an LG UltraGear 45GR95QE-B or a 38-inch ultrawide? You need the Ergotron HX. Most standard arms will literally “sag” or snap under the weight of these massive OLED panels. The HX is a beast of an arm, designed specifically for heavy-duty displays. It supports up to 42 lbs and has the most robust tilt mechanism I’ve ever seen. What I love about the HX is that despite its massive strength, it remains incredibly precise. When you tilt a 45-inch screen, you want it to stay exactly where you leave it, and the HX delivers that confidence. It’s admittedly very expensive, but if you’ve spent $1,500+ on a flagship UltraGear, putting it on a cheap arm is a recipe for disaster. This is professional-grade equipment that matches the caliber of the best monitors on the market. The installation is straightforward, and it looks stunning in a high-end setup.

Amazon Basics Single Monitor Stand View on Amazon View on B&H
Here is a little industry secret: the Amazon Basics Premium Monitor Stand is actually a rebranded Ergotron LX. It features the same basic internal mechanics and Constant Force technology but comes in a matte black finish and a shorter warranty (usually 1 year vs Ergotron’s 10). If you want that high-end, smooth-motion experience for your UltraGear but can’t justify the $200 price tag of the original, this is your best bet. It handles the 27″ and 32″ LG models with the same grace as the LX. The only downside is the aesthetic; it’s a bit more “office-utilitarian” than the sleek polished aluminum of the Ergotron. However, for sheer performance per dollar, it’s nearly unbeatable. I’ve used one of these for three years with a heavy 32-inch panel and it hasn’t lost a single millimeter of tension. It’s the smart choice for the savvy buyer.

Frequently Asked Questions
Will these arms fit the circular recess on the back of my UltraGear?
Yes, all the arms selected either have a standard 100×100 VESA plate that fits the LG circular cutout or include spacers to ensure compatibility. If you choose a different brand, always check that the VESA plate isn’t oversized, as some “universal” plates are too wide to sit inside the recessed area of the LG chassis.
Do I need a special mount for the 45-inch OLED UltraGear?
Absolutely. The 45-inch OLED models are significantly heavier and have a different center of gravity than standard displays. A typical gas spring arm will sag immediately. You specifically need a heavy-duty arm like the Ergotron HX, which is engineered to hold the weight and prevent the monitor from tilting downward involuntarily.
Can I mount an UltraGear monitor to a glass desk?
It is generally not recommended to use a C-clamp monitor arm on a glass desk, as the concentrated pressure can shatter the glass. If you must, use a large reinforcement plate to spread the load, but a better option is a free-standing desk mount or a wall-mounted arm to ensure the safety of your expensive monitor.
Is it hard to install these monitor arms?
Not at all! Most of these arms take about 15-20 minutes to install. The trickiest part is usually adjusting the tension of the gas spring. You’ll need to turn the adjustment screw (usually with an Allen key) until the monitor stays in place without rising up or falling down. Always hold the monitor securely while adjusting the tension.
Will using a monitor arm void my LG warranty?
No, using a VESA-compliant monitor arm will not void your LG warranty. LG specifically includes VESA mounting holes on their UltraGear line for this exact purpose. Just be careful during the installation process not to scratch the back of the monitor or over-tighten the screws into the monitor’s internal frame.
Final Verdict
If you have a 27″ or 32″ LG UltraGear and want the best experience, the Ergotron LX is worth every penny for its fluid movement. For those with the massive 45″ OLED, don’t compromise—get the Ergotron HX to protect your investment. If you just want to clear desk space without spending much, the VIVO mount is a reliable workhorse that won’t let you down. Your neck (and your desk) will thank you.
