Best Monitor Arm for LG UltraGear 27GP850-B
The LG UltraGear 27GP850-B is a masterpiece of IPS speed, but its stock “V-wing” stand is a notorious desk-space hog. If you’re tired of your keyboard hitting those plastic legs during intense flick shots, an aftermarket arm is the essential upgrade. After testing dozens of mounts with various 27-inch panels, I’ve found that the Ergotron LX is the gold standard for this specific monitor, balancing fluid movement with the rock-solid stability this high-refresh-rate display deserves.

Best Monitor Arm for LG UltraGear 27GP850-B: Detailed Reviews
Ergotron LX Single Monitor Arm View on Amazon
The Ergotron LX is widely considered the “buy it once” solution for a reason. Its polished aluminum construction isn’t just for show; it provides a level of structural integrity that cheaper mounts simply can’t match. When mounting the 10.6 lbs (4.8 kg) LG 27GP850-B, the LX’s Constant Force technology allows you to adjust the height, tilt, and rotation with a single finger, yet it stays exactly where you leave it. You’ll notice the lack of “monitor bounce” when typing or gaming, which is a common grievance with budget arms. It supports VESA 100x100mm perfectly, fitting into the LG’s recessed mounting bracket without needing extra spacers. While the price tag is premium, the 10-year warranty offers peace of mind. The only real drawback is the cable management—the zip-tie approach under the arm is a bit dated compared to modern snap-on plastic channels.

HUANUO Gas Spring Monitor Mount View on Amazon
For those who want the functionality of a premium arm without the three-figure investment, the HUANUO Gas Spring Mount is an incredible value proposition. It handles the weight of the LG UltraGear series with ease, providing enough tension to keep the monitor stable during aggressive gaming sessions. I find the installation process surprisingly straightforward, thanks to the included C-clamp and grommet mounting options. The cable management system uses integrated plastic covers that look cleaner than the Ergotron’s solution, though they can be a bit tight if you’re running thick DisplayPort and power cables. You do lose some of the silky-smooth refinement of higher-end models—expect a bit more resistance when making fine adjustments—but for the price, it’s hard to beat. It’s the perfect middle ground for users who want a clean desk aesthetic on a sensible budget.

VIVO Single Monitor Desk Mount View on Amazon
If you don’t need to constantly move your monitor around and just want it off your desk, the VIVO Single Monitor Mount is the ultimate “set-and-forget” tool. Unlike gas spring arms, this uses a solid steel pole and a mechanical clamp. To adjust the height, you manually slide the arm up or down the pole and tighten a bolt. It’s not elegant, but it’s incredibly sturdy. For the LG 27GP850-B, this provides a massive boost in desk real estate for less than the cost of a new game. The honest limitation here is the lack of “on-the-fly” height adjustment; if you switch between sitting and standing often, this will frustrate you. However, for a dedicated gaming desk where the height remains constant, the VIVO’s simplicity is its greatest strength. It’s built like a tank and handles the 27-inch UltraGear without a hint of sagging.

Herman Miller Flo Monitor Arm View on Amazon
The Herman Miller Flo is for the user who views their workspace as an art installation. While the LG 27GP850-B is a gaming monitor, many use it for creative work where aesthetics matter. The Flo uses a unique geometric spring rather than a gas cylinder, which results in even smoother motion and a significantly slimmer profile. You’ll notice the integrated weight gauge, which allows you to dial in the tension perfectly for the LG’s specific weight before you even mount it. It offers a massive range of motion, including a great “D-ring” swivel that makes sharing your screen with a colleague effortless. It’s expensive, but it represents the pinnacle of industrial design. The build quality is flawless, and it carries the prestige of the Herman Miller brand. If you want your desk to look like it belongs in a tech CEO’s office, this is the one.

North Bayou NB-F80 View on Amazon
The North Bayou NB-F80 is a cult favorite in the gaming community for being the most affordable functional gas-spring arm on the market. It’s surprisingly robust for its price point and holds the LG 27GP850-B quite securely. I’ve noticed that it actually offers a better range of tilt (+85° to -30°) than some models twice its price, which is great if you use your monitor for top-down creative work or if you’re standing. The base is quite compact, making it ideal for smaller desks where every inch counts. The downsides? The cable management is basic, and the yellow “NB” branding is a bit loud for some tastes. However, if you spent all your money on the LG’s Nano IPS panel and need a mount that “just works” for the price of a few pizzas, the NB-F80 is a legendary choice.

Frequently Asked Questions
Will these arms fit the recessed VESA mount on the LG 27GP850-B?
Yes, most modern monitor arms include spacers or have a VESA plate small enough to fit inside the circular recession on the back of the UltraGear. The Ergotron LX and HUANUO models mentioned here fit perfectly without modification, ensuring a secure and flush mount every time.
Can I use a dual-arm mount if I have two 27GP850-B monitors?
Absolutely, but be careful with desk weight distribution. Two 27-inch monitors put significant stress on a single point of your desk. I recommend using two individual arms or a high-quality dual-arm like the Ergotron LX Dual for better flexibility and weight management across the desk surface.
Do I need tools to install these monitor arms?
Most arms come with the necessary Allen keys for assembly and tension adjustment. You may need a Phillips-head screwdriver to attach the VESA plate to the back of your LG monitor, but the actual desk mounting process is usually tool-free via a hand-tightened C-clamp.
Will an arm stop my monitor from shaking while I type?
A high-quality arm like the Ergotron LX will significantly reduce wobble compared to the stock LG stand. However, some vibration is inevitable if your desk itself is unstable. For the best results, ensure your desk is sturdy and the arm’s tension is properly adjusted for the monitor’s weight.
Does mounting the monitor void the LG warranty?
No, using a third-party VESA mount does not void your warranty. LG specifically designs these monitors with VESA 100x100mm holes for this exact purpose. Just be careful not to over-tighten the screws, as you don’t want to damage the internal threads or the panel housing.
Final Verdict
If you want the absolute best experience for your LG 27GP850-B, the Ergotron LX is the clear winner for its longevity and fluid movement. However, the HUANUO Gas Spring offers 90% of that performance for a fraction of the cost, making it the smarter buy for most gamers. For those on a strict budget who just want to reclaim their desk space, the VIVO mount is a flawless, no-frills alternative.
