Best Monitor Arm for LG UltraGear 27GP850-B
The LG UltraGear 27GP850-B is a beast of a gaming monitor, but its stock “V-wing” stand is a total desk-space hog. If you’re tired of your keyboard hitting the stand legs during flick shots, a dedicated monitor arm is the only real solution. After testing dozens of mounts with various UltraGear models, I’ve found that the Ergotron LX offers the best stability and range of motion. Here is how to reclaim your desk and perfect your ergonomic setup.

Best Monitor Arm for LG UltraGear 27GP850-B: Detailed Reviews
Ergotron LX Single Monitor Arm View on Amazon
The Ergotron LX is the undisputed gold standard for a reason. When mounting the LG 27GP850-B, you need an arm that handles the specific 100x100mm VESA pattern without interfering with the circular recess on the back of the monitor. The LX plate fits perfectly. I find the patented Constant Force technology exceptional; it allows you to move the screen with a literal pinky finger, yet it stays exactly where you leave it. Since the 27GP850-B weighs only about 10.6 lbs without the stand, this arm isn’t even breaking a sweat. The polished aluminum construction looks premium and feels indestructible. While it is an investment, the 10-year warranty means this is the last monitor arm you’ll ever buy. The only minor drawback is the cable management clips can be a bit tight for thick DisplayPort cables, but that’s a small price for this level of stability.

HUANUO Gas Spring Monitor Mount View on Amazon
The HUANUO Gas Spring mount is the “sweet spot” choice for most UltraGear owners. It offers about 85% of the performance of high-end arms at a fraction of the cost. The gas spring mechanism is surprisingly smooth; once you tension it correctly for the LG’s weight, you’ll notice that height adjustments feel effortless. I particularly appreciate the versatility of the mounting options—it comes with both a sturdy C-clamp and a grommet base. For the 27GP850-B, the tilt range is excellent, which is vital if you like to switch between an aggressive gaming posture and a relaxed movie-watching lean. The build quality is mostly metal with some plastic shrouds for cable routing. It doesn’t feel quite as “tank-like” as the Ergotron, and the tilt joint requires a bit more tightening to prevent sag, but for the price, the value proposition is simply unbeatable for a 27-inch display.

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 your best friend. This is a pole-style mount rather than a gas spring arm. This means you set the height manually on the pole and lock it in. While it lacks the “floating” feel of more expensive arms, it is incredibly stable. For the LG 27GP850-B, this provides a rock-solid foundation with zero wobble during intense gaming sessions. The installation is straightforward, though you’ll need to use the included spacers if the LG’s circular housing is too deep for the VESA plate. It’s an honest, no-frills piece of hardware. The main limitation is the lack of easy vertical adjustment on the fly, but if you have a fixed desk height, this is the most cost-effective way to clean up your workspace without compromising on safety.

Herman Miller Flo Monitor Arm View on Amazon
The Herman Miller Flo is a masterpiece of industrial design. While most arms use bulky gas springs, the Flo uses a unique geometric spring system that provides unparalleled smoothness. It is specifically designed for lighter monitors like the 27GP850-B, offering a range of motion that feels more like “guiding” the monitor than pushing it. You’ll love the visual aesthetic—it’s sleek, white (or black/silver), and lacks the industrial “robotic” look of the Ergotron. The integrated weight gauge allows you to perfectly calibrate the tension for the LG display in seconds. I’ve found that the Flo excels at keeping the monitor close to the back of the desk, which is great for shallow setups. It is undeniably expensive, but the build quality and the sheer elegance it adds to a high-end setup are unmatched. It’s the ultimate choice for those who view their desk as a piece of art.

Amazon Basics Premium Monitor Arm View on Amazon
Here is a little secret in the tech world: the Amazon Basics Premium Monitor Arm is actually a rebranded Ergotron LX. It features the same heavy-duty construction and many of the same internal mechanisms, but usually costs about 20-30% less. For the LG 27GP850-B, it provides the same elite-level stability and fluid movement. The finish is a matte black which actually matches the LG’s chassis better than the polished Ergotron version. So, why isn’t it the “Best Overall”? It only carries a 1-year warranty compared to Ergotron’s 10-year guarantee, and the aesthetics are a bit more utilitarian. However, if you want the best possible mechanical performance for your 27-inch gaming monitor and don’t care about the brand name on the box, this is the smartest purchase you can make. It handles the weight easily and provides plenty of extension for deep desks.

Frequently Asked Questions
Does the LG 27GP850-B need a VESA adapter?
No, the LG 27GP850-B features a standard VESA 100x100mm mounting pattern directly on the back. However, the mounting area is recessed within a circular housing. While most modern monitor arms fit this perfectly, some older or very bulky VESA plates might require the use of spacers (usually included with the arm) to sit flush. You won’t need to buy a separate third-party adapter plate, as the monitor is designed for standard mounts.
Are gas spring arms better than mechanical ones?
It depends on your usage. Gas spring arms, like the HUANUO, offer very fluid, “weightless” movement which is great if you adjust your monitor multiple times a day. However, gas springs can eventually lose tension over many years. Mechanical spring arms, like the Ergotron LX, tend to be more durable and provide a more tactile, controlled movement. For the relatively light LG UltraGear, both options work excellently, but mechanical arms usually offer better long-term reliability.
Can I mount this monitor on a glass desk?
I generally advise against mounting a C-clamp monitor arm directly onto a thin glass desk, as the concentrated pressure can shatter the glass. If you must use a glass desk, look for a “monitor mount reinforcement plate” which spreads the load across a larger surface area. Alternatively, a grommet mount through a pre-drilled hole is slightly safer, but a solid wood or metal-frame desk is always the preferred choice for a monitor arm.
Will a monitor arm stop my screen from wobbling?
A high-quality monitor arm like the Ergotron LX will significantly reduce wobble compared to the stock LG stand, especially if your desk is sturdy. However, if your desk itself is flimsy, any arm will still transmit that motion to the screen. To eliminate wobble for the 27GP850-B, ensure the arm’s tension is tightened correctly and that the C-clamp is tightened as far as possible to the desk’s underside. High-end arms have better dampening.
How do I manage cables with a monitor arm?
Most arms, including the HUANUO and Ergotron, have built-in cable management channels or clips. When setting up your LG UltraGear, I recommend leaving a “service loop” (extra slack) near the monitor’s pivot point. This ensures that when you rotate or extend the arm, the cables don’t pull tight and damage the ports. Using Velcro ties instead of zip ties makes it much easier to swap out cables later if you upgrade your PC.
Final Verdict
For the serious gamer using the LG 27GP850-B, the Ergotron LX is worth every penny for its stability and 10-year lifespan. If you’re on a tighter budget but still want that “floating” monitor look, the HUANUO Gas Spring provides excellent utility without breaking the bank. Finally, the VIVO mount is perfect for those who simply want to reclaim desk space and don’t need frequent height adjustments. Choose the arm that matches your daily movement needs!
