LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor Review: The Ultimate Do-It-All Display?

For years, my desk has been a revolving door of displays, each one a compromise. I’ve had ultra-fast 1080p monitors where competitive gaming felt incredible, but reading an email felt like deciphering ancient runes. I’ve tried pristine 4K IPS panels that made photo editing a dream, but their sluggish response times left ghostly trails in fast-paced games. The promise of ultrawide OLED was tantalizing, offering unparalleled contrast and immersion, but early models were plagued by low resolutions and text fringing that made them a non-starter for productivity. The holy grail has always been a single monitor that could deliver razor-sharp text for an eight-hour workday, then seamlessly transition into a breathtakingly immersive, lightning-fast portal for gaming. It’s a problem many enthusiasts and professionals face: the need to choose between clarity and speed. This constant compromise is not just inconvenient; it clutters our desks, complicates our setups, and ultimately, holds back the true potential of our powerful PCs. The quest for one monitor to rule them all has felt, until now, like an impossible dream.

What to Consider Before Buying a High-End Gaming Monitor

A high-end gaming monitor is more than just a screen; it’s a key solution for unlocking the full potential of your gaming rig and a critical tool for productivity. It solves the problem of visual compromise, offering a window into digital worlds with the clarity, color, and speed their creators intended. The main benefits are profound: heightened immersion that pulls you into the game, a competitive edge from faster refresh rates and response times, and reduced eye strain from sharper text and better screen coatings. It transforms a simple computer setup into a premium, multi-purpose entertainment and work station.

The ideal customer for this type of product is someone facing the classic dilemma of work and play. They are serious PC gamers, content creators, programmers, or sim-racing enthusiasts who spend hours at their desk and refuse to compromise on either visual fidelity for creative work or raw performance for gaming. They understand the investment required for top-tier components and see a monitor as the final, crucial piece of the puzzle. Conversely, this monitor might not be suitable for those who are casual users, console gamers (as many consoles don’t fully support ultrawide resolutions), or those on a strict budget. For them, a more conventional 16:9 4K or 1440p monitor might offer a better value proposition without the premium features they wouldn’t use.

Before investing, consider these crucial points in detail:

  • Dimensions & Space: A 45-inch ultrawide monitor is a colossal piece of hardware. You must measure your desk space to ensure it can accommodate not just the 39-inch width, but also the significant depth required by the stand. Consider the aggressive 800R curve; you need to be able to sit at the optimal viewing distance (typically within arm’s length) to truly benefit from the immersion and avoid excessive head movement.
  • Capacity/Performance: This is a dual-threat consideration. For resolution, 5K2K (5120×2160) is incredibly demanding, requiring a high-end graphics card (think NVIDIA RTX 4080/4090 or AMD equivalent) to run modern games at high settings. For speed, consider the “Dual Mode”: are you a competitive player who will actually use the 330Hz WFHD mode, or are you more focused on the cinematic 165Hz 5K2K experience? Your GPU must be able to drive these demanding specs.
  • Materials & Durability: High-end monitors should feel premium. Look for a solid metal stand, minimal plastic creak, and a high-quality chassis. For OLED panels specifically, durability means considering burn-in mitigation features. LG’s inclusion of pixel cleaning and other OLED Care functions is a critical long-term durability feature that protects your investment.
  • Ease of Use & Maintenance: A good monitor should be easy to set up and adjust. Tool-less assembly is a huge plus. On the software side, an intuitive On-Screen Display (OSD) menu or desktop software makes tweaking settings much less of a chore. For maintenance, an anti-glare matte screen finish is easier to clean and reduces reflections compared to glossy panels, which is vital for long sessions.

Keeping these factors in mind, the LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor stands out in several areas. You can explore its detailed specifications here.

While the LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: An All-Encompassing Visual Experience

Unboxing the LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor is an event in itself. The sheer size of the box hints at the command this display will have over your desk. As confirmed by other users, the packaging is superb, cradling the massive, curved panel securely in dense foam. Lifting it out, the first thing I noticed was the solid build quality; the chassis feels robust, and the metal components of the stand have a reassuring heft. Assembly was shockingly simple and, as one owner noted, entirely tool-free. The stand clicks into the back of the panel, and the base attaches with a single, convenient thumbscrew. From box to fully assembled, it took less than five minutes.

Powering it on for the first time is a “wow” moment. The 45-inch screen, combined with the aggressive 800R curve, immediately fills your entire field of view. It’s less like looking at a monitor and more like looking through a window into your desktop. The colors pop with that signature OLED vibrancy, and the blacks are truly, perfectly black. Compared to my previous 38-inch ultrawide, this feels like a significant leap, not just in size, but in the sheer sense of immersion. It’s a bold, futuristic design that makes a statement before you even launch a game.

A Deep Dive into the Future of Display Technology

After spending weeks putting the LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor through its paces—from marathon coding sessions to intense gaming tournaments—it’s clear this isn’t just an incremental upgrade. It’s a fundamental shift in what a single display can achieve. It masterfully blends capabilities that were previously mutually exclusive, creating an experience that is, in a word, transformative.

The 5K2K Resolution and Text Clarity Revolution

The single greatest achievement of this monitor is its panel. For years, OLED gaming monitors forced a painful choice: accept a grainy, pixelated desktop experience in exchange for perfect blacks and fast response times. The LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor shatters that compromise. Its 5120×2160 (5K2K) resolution spread across a 44.5-inch screen results in a pixel density of 125 PPI. This is the magic number. It’s a massive leap from previous 45-inch ultrawides that hovered around a dismal 84 PPI.

The real-world impact is immediate and profound. Text is razor-sharp. I spent hours working in Visual Studio Code and browsing documents, and my eyes felt noticeably less strained than on other OLEDs. This is confirmed by users upgrading from OLED TVs like the LG C2, who specifically praise the text rendering. The secret sauce is LG’s RGWB subpixel layout, which is far better suited for the subpixel anti-aliasing used by Windows and macOS than the problematic layouts of past OLEDs. Color fringing on text is virtually eliminated. For the first time, I have an OLED ultrawide on my desk that I can unreservedly recommend for productivity. You get the vast horizontal real estate to have multiple windows open side-by-side, but with the pixel density to make every character on screen crisp and legible. It truly feels like having two high-resolution monitors seamlessly stitched together.

Dual-Mode Gaming: The Best of Both Worlds

LG’s “Dual Mode” technology is a stroke of genius and a killer feature for versatile gamers. With a simple press of a button, you can switch between two distinct performance profiles. The first is the native 5K2K resolution at a silky-smooth 165Hz. Firing up a visually stunning title like *Cyberpunk 2077* or *Alan Wake 2* in this mode is an unparalleled cinematic experience. The combination of the immersive 800R curve, the infinite contrast of OLED, and the fluid 165Hz refresh rate makes game worlds feel incredibly real and tangible. The 0.03ms response time means there is absolutely zero ghosting or motion blur, just pure visual clarity, even in the most chaotic scenes.

Then, there’s the second mode. For competitive first-person shooters like *Valorant* or *Apex Legends*, you can switch the monitor to a 3840×1600 (WFHD-ish) resolution and crank the refresh rate to an eye-watering 330Hz. The drop in resolution is noticeable, but in the heat of competition, the priority is refresh rate and response time. The fluidity at 330Hz provides a tangible competitive advantage, making it easier to track fast-moving targets and react instantly. This feature single-handedly solves the specialist monitor problem. You no longer need one screen for immersive RPGs and another for competitive esports; the LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor capably fills both roles. For any gamer who plays a wide variety of genres, this dual-mode functionality is a game-changer.

Immersion and Design: Living with an 800R Curve

The 800R curvature is aggressive, and it’s the most subjective aspect of this monitor. For some, it might be too much. For me, and for specific applications, it’s perfect. The curve is designed to match the general curvature of human vision, and at this massive 45-inch size, it works wonders to keep the screen’s edges within your peripheral vision. This dramatically reduces the need to turn your head, making the experience more comfortable and immersive over long sessions.

This is particularly true for simulation games. As one user who is an avid sim-racer on iRacing noted, the field of view is more than enough to be competitive without needing a complex triple-monitor setup. The curve wraps the track around you, enhancing the sense of speed and spatial awareness. The same applies to first-person adventure games and flight simulators. The anti-glare matte screen finish is another huge win, effectively taming reflections without dulling the vibrancy of the OLED panel, a critical feature for maintaining immersion in varied lighting conditions. The stand is also highly ergonomic, offering height, tilt, and swivel adjustments, ensuring you can find the perfect position for your setup.

Future-Proof Connectivity and Essential OLED Care

On the connectivity front, LG has equipped this monitor for the future. The inclusion of DisplayPort 2.1 is a significant feature, offering a massive bandwidth pipe that will be crucial for next-generation graphics cards driving even higher resolutions and refresh rates. The two HDMI 2.1 ports are perfect for current-gen consoles and other devices. For productivity, the USB Type-C port with 90W Power Delivery is a fantastic quality-of-life feature, allowing you to connect and charge a modern laptop with a single cable, reducing desk clutter.

More importantly, LG has addressed the elephant in the room for any OLED display: burn-in. The monitor includes a suite of “OLED Care” features. The most critical of these, as discovered by several users, is the “OLED Image Cleaning” function. A number of owners reported receiving units with faint vertical lines visible on the screen—a common issue with large OLED panels after shipping. However, running the manual pixel cleaning cycle almost entirely eliminated these artifacts, restoring a perfect image. This is a crucial piece of information for potential buyers: what might seem like a defective panel out of the box can often be fixed with a built-in maintenance tool. This proactive approach to panel longevity provides peace of mind for such a significant investment.

What Other Users Are Saying

The sentiment surrounding the LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor is overwhelmingly positive, often bordering on ecstatic. One user, after waiting five years for the perfect monitor, called it “a full-on experience” that “exceeded all expectations,” praising the unprecedented combination of OLED, resolution, and refresh rate. Another who uses it for sim racing declared that “youtube videos and pictures dont give this monitor enough credit” and that the image quality with its “super inky black” colors is terrific for competitive play.

However, the experience hasn’t been flawless for everyone. The most common complaint centers around quality control. Several users reported receiving monitors with issues straight out of the box, ranging from dead pixels right in the center of the screen to persistent vertical lines. As one user recounted, “I ordered one… it looked great until I turned it on. As I was setting it up I noticed white lines going from the top to the bottom.” While some of these issues were resolved with replacements or by using the built-in OLED Image Cleaning function, it’s a frustrating first experience for a premium product. One particularly critical user also found the colors “dull compared to QD-OLED,” suggesting that while LG’s WOLED technology is fantastic for text and contrast, some may prefer the color vibrancy of competing panel tech.

How Does the LG 45GX950A-B Compare to the Alternatives?

The LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor sits at the pinnacle of the market, but its price and features aren’t for everyone. Here’s how it stacks up against some popular alternatives.

1. ASUS TUF VG34VQL1B 34 Inch WQHD 165Hz Gaming Monitor

Sale
ASUS TUF 34 Inch Curved Gaming Monitor - WQHD (3440x1440), 165Hz, 1ms, Extreme Low Motion Blur,...
  • 34-inch WQHD (3440x1440) 1500R curved gaming monitor with ultra-fast 165Hz (supports 144Hz) refresh rate designed for professional gamers and immersive gameplay

  • Viewing Angle is 178° (H) / 178° (V); Brightness is 300nits; Aspect Ratio is 21:9
  • Mystic Light – The ultimate gaming finish

Similar to the ASUS TUF, the MSI Optix MAG342CQR targets the mainstream ultrawide gaming market. It features a 34-inch, 3440×1440 VA panel with a slightly lower 144Hz refresh rate and a more gentle 1500R curve. Its primary appeal is its competitive price point, offering an entry into immersive ultrawide gaming without a huge financial commitment. The MSI is a solid performer for its price, but it can’t compete with the LG’s sheer visual fidelity, speed, or feature set. This monitor is best for budget-conscious builders who want to dip their toes into the 21:9 aspect ratio and prioritize value over bleeding-edge technology.

3. ViewSonic VS2747-H 27″ 1080p IPS 100Hz Monitor

  • ACCURATE FROM ALL ANGLES: Enjoy accurate and vivid colors with consistent levels of brightness with SuperClear IPS technology.
  • ENHANCED VIEWING COMFORT: Flicker-Free technology and Blue Light Filter for reduced eye fatigue

The ViewSonic VS2747-H exists in a completely different category and serves as a reality check for what most users might need. It’s a standard 16:9, 27-inch 1080p IPS monitor. It’s not curved, not ultrawide, and has a modest 100Hz refresh rate. Comparing it to the LG is like comparing a reliable family sedan to a Formula 1 car. However, for general desktop use, light gaming, and office work on a tight budget, it is a perfectly sensible choice. This monitor is for someone who needs a functional, no-frills display and isn’t chasing the ultimate immersive experience or competitive edge. It highlights just how specialized and premium the LG 45GX950A-B truly is.

Final Verdict: A Groundbreaking Monitor for the Discerning User

The LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor is, without a doubt, one of the most ambitious and impressive displays I have ever tested. It successfully bridges the chasm between productivity clarity and gaming supremacy in a way no monitor has before. The stunning 5K2K OLED panel, with its 125 PPI and excellent text rendering, makes it a genuine workhorse, while the Dual-Mode refresh rate and instantaneous response time make it an absolute gaming monster. The immersive 800R curve and sheer size create an experience that has to be seen to be believed.

It is not without its caveats. The price is substantial, and the potential for out-of-the-box quality control issues is a valid concern. This is a monitor for the enthusiast who has a powerful PC to match and demands the absolute best without compromise. It is for the professional who codes all day and games all night, or the sim-racer who craves ultimate immersion. For that user, the LG 45GX950A-B is not just a monitor; it’s an endgame display that delivers on almost every promise. It’s a true glimpse into the future of desktop monitors.

If you’ve decided the LG 45GX950A-B 45-inch 5K2K OLED Curved Gaming Monitor is the right fit, you can check its current price and purchase it here.
