For years, my quest for the “perfect” gaming monitor felt like a journey with no destination. As a reviewer and an avid gamer, I’ve been caught in the crossfire of compromises. Do I choose an IPS panel for its vibrant colors, knowing I’ll have to accept slower response times and the dreaded “IPS glow”? Or do I opt for a lightning-fast TN panel, sacrificing visual fidelity for a competitive edge? It’s a frustrating trade-off that has defined the monitor market for over a decade. We invest thousands in powerful graphics cards capable of rendering breathtaking worlds, only to have that beauty muted or that speed blurred by the final link in the chain: the display. This compromise isn’t just an inconvenience; it’s a barrier to true immersion and peak performance. The wrong monitor can make a fast-paced shooter feel sluggish or a cinematic masterpiece look washed out, fundamentally cheapening the entire gaming experience.

What to Consider Before Buying a High-Performance Gaming Monitor
A gaming monitor is more than just a screen; it’s a window into digital worlds and a critical tool for competitive success. It’s the key solution for translating your PC’s raw power into a tangible, visible, and interactive experience. The main benefits are profound: a high-refresh-rate monitor provides a smoother, more responsive feel that can give you a measurable advantage in fast-paced games, while a panel with superior color and contrast brings virtual environments to life with stunning realism, enhancing immersion and making every session more enjoyable. It bridges the gap between hardware and perception, ensuring you see every frame your GPU renders with absolute clarity.
The ideal customer for a product like the LG 27GX704A-B 27-inch OLED Gaming Monitor 240Hz is a serious enthusiast or competitive player facing the limitations of older technologies. This is someone who craves both unparalleled motion clarity and breathtaking visual quality without compromise. They likely own a mid-to-high-end gaming PC and want a display that can keep up. Conversely, this type of monitor might not be suitable for those on a strict budget, or for users who primarily perform static productivity tasks like writing or coding for extended periods, as the unique subpixel layout of OLEDs can sometimes affect text clarity. For those users, a high-resolution 4K IPS monitor might be a better alternative.
Before investing, consider these crucial points in detail:
- Panel Technology & Screen Finish: The heart of any monitor is its panel. OLED (Organic Light Emitting Diode) technology, used here, offers per-pixel lighting for perfect blacks and infinite contrast, something traditional LCD panels (IPS, VA, TN) with backlights cannot achieve. However, consider the screen finish; a glossy screen like this one makes colors pop vibrantly but can be susceptible to reflections in a brightly lit room.
- Performance Metrics: For gaming, three numbers are paramount: resolution, refresh rate, and response time. QHD (2560×1440) resolution is the current sweet spot for 27-inch monitors, offering sharp detail without being as graphically demanding as 4K. A 240Hz refresh rate means the screen updates 240 times per second for incredibly smooth motion, while the 0.03ms response time ensures there’s virtually no ghosting or blurring behind moving objects.
- Ergonomics & Durability: A monitor should adapt to you, not the other way around. Look for a stand with comprehensive adjustments—tilt, height, swivel, and pivot—to ensure comfortable viewing angles and prevent neck strain. For OLEDs, durability also involves considering features designed to mitigate burn-in, such as pixel shifting and screen cleaning cycles, which this LG model includes.
- Connectivity & Features: Ensure the monitor has the ports you need. HDMI 2.1 and DisplayPort 1.4 are essential for achieving high refresh rates at high resolutions. Additional features like NVIDIA G-SYNC and AMD FreeSync Premium Pro are critical for eliminating screen tearing by synchronizing the monitor’s refresh rate with your graphics card’s output.
Choosing the right monitor is a significant decision that impacts every moment you spend at your computer. It’s about finding the perfect balance of features that align with your primary use case.
While the LG 27GX704A-B 27-inch OLED Gaming Monitor 240Hz is an excellent choice for gamers seeking the best of QHD performance, it’s always wise to see how it stacks up against the competition, especially if you’re considering a higher resolution.

First Contact: Unboxing and Assembling the Future of Gaming
From the moment the courier dropped off the box, I could tell LG meant business. The packaging for the LG 27GX704A-B 27-inch OLED Gaming Monitor 240Hz is robust and intelligently designed, echoing a sentiment from one user who noted it “arrived packaged extremely well to keep it safe.” Inside, the panel itself is shockingly thin, a hallmark of OLED technology where no separate backlight layer is needed. The stand components feel substantial and well-machined, with a reassuring heft that speaks to quality materials.
Assembly was a tool-free, refreshingly simple process. The base screws into the stand arm by hand, and the entire assembly clicks securely into the back of the monitor. Within two minutes, it was standing on my desk, ready to go. The design is classic UltraGear: sleek, aggressive, but not overly flashy. The virtually borderless design on three sides enhances immersion, while the hexagonal RGB lighting on the back adds a touch of customizable flair for your battle station. The glossy screen finish was the first thing I noticed; in my moderately lit office, it immediately made the powered-off screen look like a deep, inky black mirror, a promising sign of the contrast to come.

Deep Dive: Analyzing the LG 27GX704A-B’s On-Screen Performance
A spec sheet can only tell you so much. To truly understand a monitor, you have to live with it, play on it, and push it to its limits. Over the past week, I’ve put the LG 27GX704A-B 27-inch OLED Gaming Monitor 240Hz through its paces with everything from fast-paced esports titles to visually stunning single-player epics and even some daily productivity work. The results were, in a word, transformative.
The OLED Difference: A Visual Revolution in Gaming
Switching from a high-end IPS monitor to this LG OLED felt like getting new glasses I didn’t know I needed. The difference is immediate and profound. Firing up Cyberpunk 2077: Phantom Liberty, the rain-slicked streets of Night City weren’t just dark grey; they were a true, deep black, punctuated by neon signs that blazed with an intensity and purity that LCD backlights simply cannot replicate. Because each of the 3.7 million pixels generates its own light, there is zero blooming or haloing around bright objects on dark backgrounds. This per-pixel control creates a sense of depth and realism that is utterly captivating. As one user aptly put it, “The OLED panel looks absolutely amazing… video games just feel next level gorgeous and immersive.”
This is further enhanced by the DisplayHDR True Black 400 certification. In a game like Alan Wake 2, navigating the dark forests around Cauldron Lake was a genuinely tense experience. Flashlight beams cut through the absolute blackness with startling clarity, and shadows held detail without being crushed into a murky grey mess. The 1,500,000:1 contrast ratio isn’t just a marketing number; it’s a tangible reality that makes every scene, from the brightest day to the darkest night, pop with cinematic quality. The 98.5% DCI-P3 color gamut coverage ensures these visuals are not only contrasted but also incredibly rich and vibrant, without looking oversaturated. It’s a visual experience that has to be seen to be believed, and it represents a feature that truly sets this monitor apart from its LCD counterparts.
Need for Speed: 240Hz and 0.03ms Response Time in Action
While the visual fidelity is breathtaking, LG’s UltraGear line is built for speed, and the LG 27GX704A-B 27-inch OLED Gaming Monitor 240Hz is an absolute speed demon. In competitive shooters like Valorant and Apex Legends, the combination of a 240Hz refresh rate and the near-instantaneous 0.03ms (GtG) response time is nothing short of a competitive advantage. The difference is stark. On traditional LCDs, even fast ones, there’s a tiny amount of visible blur or “ghosting” when you quickly flick your mouse to track an enemy. On this OLED, that phenomenon is completely gone. Targets remain perfectly crisp and defined, no matter how fast you move your crosshair. This level of motion clarity allows for more precise tracking and targeting, making it easier to land those crucial shots.
To ensure this silky-smooth experience is never interrupted, the monitor is both NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro certified. I tested it with my RTX 4080, and G-SYNC engaged flawlessly, eliminating any hint of screen tearing or stuttering when the framerate fluctuated. The result is a locked-in, liquid-smooth experience that feels directly connected to your inputs. The “Dynamic Action Sync” feature further minimizes input lag, making the entire experience feel incredibly responsive. For any gamer who plays competitively, the speed and clarity offered by this monitor aren’t just a luxury; they are a fundamental improvement to gameplay that can be explored further on its product page.
Living with the LG 27GX704A-B: Ergonomics and Daily Use
A great gaming monitor also needs to be a great everyday monitor, and LG has nailed the practicalities. The stand is one of the best I’ve used, offering a generous range of height, tilt, swivel, and even a full 90-degree pivot into portrait mode. This flexibility makes it easy to find the perfect ergonomic position for long sessions, reducing neck and eye strain. The On-Screen Display (OSD) is controlled by a simple joystick and is intuitive to navigate, providing access to a suite of “Pro Gaming Tools” like Black Stabilizer (which brightens dark areas to reveal enemies) and a hardware-based crosshair and FPS counter.
On the topic of daily use, it’s important to address the one potential quirk of OLED panels: text clarity. As one user noted, “text clarity is nit great… with black text over a light background.” This is due to the non-standard subpixel layout of WRGB OLED panels. I can confirm that if you look very closely at black text on a white background, you might notice some slight color fringing. However, I found this to be a minor issue that I quickly stopped noticing, and as the user correctly pointed out, if you use dark mode for your OS and applications, the problem effectively vanishes. It’s a small trade-off for the immense gains in media and gaming performance. Furthermore, LG has included a suite of OLED Care tools to protect the panel. After my initial setup, I noticed some slight color banding, but as another user experienced, running the manual “Pixel Cleaning” function from the menu completely resolved it, and the image has been flawless since. These thoughtful features provide peace of mind for your investment, which you can confirm by checking the latest price and availability.
What Other Users Are Saying
Our overwhelmingly positive experience is strongly mirrored in the feedback from other users. The sentiment is clear: this monitor is a significant upgrade, especially for those coming from older IPS technology. One user declared it a “game changer from ips 1440p,” a sentiment I wholeheartedly agree with. The praise for the core visual experience is universal, with comments like “the immersion and the quality of the screen is absolutely stunning” and “smooth and gorgeous” being common themes.
The practical aspects also receive high marks. Multiple users praised the “very sturdy” stand and the excellent, protective packaging. The inclusion and effectiveness of the OLED care tools, specifically the Pixel Cleaning function that resolved a color banding issue for one user out of the box, adds a layer of confidence for new adopters of the technology.
The criticisms, while valid, are minor and characteristic of the technology. The most common point is the text clarity on bright backgrounds, though most, like us, find it to be a non-issue in dark mode or for gaming. Another user mentioned the brightness is “not retina burning kind of bright,” which is true—OLEDs typically have lower full-screen brightness than the brightest LCDs, but they compensate with perfect contrast for a perceived brightness that is still incredibly impactful, especially for HDR content.
How Does the LG 27GX704A-B Compare to the Alternatives?
The LG 27GX704A-B 27-inch OLED Gaming Monitor 240Hz is a specialized piece of equipment for high-performance gaming. To understand its value, it’s helpful to compare it against other monitors designed for different purposes.
1. Asus ProArt PA248QV 24.1″ WUXGA Monitor
- 24. 1-inch 16: 10 WUXGA (1920 x 1200) IPS display with frameless design
- International color standard 100% sRGB and 100% Rec. 709 wide color gamut. Brightness (Typ.) is 300cd/㎡
The Asus ProArt is built for an entirely different user: the professional content creator. Its focus is not on speed but on absolute color accuracy. With a Calman Verified certification and a guaranteed Delta E < 2, it’s designed for tasks like photo editing, graphic design, and video grading where precise color reproduction is non-negotiable. Compared to the LG, it has a lower resolution, a much lower 75Hz refresh rate, and a standard IPS panel. A gamer would be disappointed by its motion performance, but a creative professional would choose the ProArt for its unparalleled color fidelity in its price class.
2. ViewSonic VA3209M 32 Inch FHD Monitor
- VERSATILE MONITOR: 32 Inch Full HD (1920x1080p) IPS monitor with thin bezels and 75Hz refresh rate
- ENHANCED VIEWING COMFORT: Flicker-Free technology and Blue Light Filter for reduced eye fatigue
The ViewSonic represents the budget-friendly, general-use end of the spectrum. Its main selling points are its large 32-inch screen size and its affordability. However, it makes significant compromises to get there. The Full HD (1080p) resolution is very low for a 32-inch screen, resulting in a pixelated image, and its 75Hz refresh rate is the bare minimum for smooth desktop use. This monitor is a good choice for someone who needs maximum screen real estate for basic office work or browsing on a tight budget, but it lacks the resolution, speed, and visual quality required for an immersive gaming experience like the LG provides.
3. Dell U2723QE 27″ 4K UHD Monitor
- Exceptional contrast: Experience incredible color and superior black performance with a contrast ratio of 2000:1 on the world’s first 27" 4K monitor with IPS Black technology. *Based on Dell...
- ComfortView Plus*—an always-on, built-in low blue light screen—reduces potentially harmful blue light emissions without compromising color. *TÜV Rheinland certified – Low Blue Light Hardware...
The Dell UltraSharp U2723QE is a direct competitor in the premium 27-inch space, but it targets productivity, not gaming. Its key feature is its 4K UHD resolution, which packs over 8 million pixels into the screen for incredibly sharp text and images. This makes it an outstanding choice for programmers, writers, and anyone who works with detailed documents or high-resolution timelines. However, its refresh rate is capped at 60Hz, making it unsuitable for high-framerate gaming. If your primary use is work and you value pixel density above all, the Dell is a top-tier choice. If gaming is your priority, the LG’s superior speed and contrast deliver a far better experience.
The Final Verdict: Is the LG 27GX704A-B Worth It?
After extensive testing, we can say without hesitation that the LG 27GX704A-B 27-inch OLED Gaming Monitor 240Hz is a phenomenal piece of gaming hardware. It successfully eliminates the long-standing compromise between speed and visual quality. You get the blistering motion clarity of an esports-grade monitor combined with the stunning contrast and color of a high-end entertainment display. The perfect blacks, instantaneous response time, and fluid 240Hz refresh rate create an experience that genuinely elevates every game you play.
While the glossy screen won’t be for every room setup and professionals who stare at static text all day might prefer a 4K IPS panel, these are minor trade-offs for its intended audience. For the dedicated gamer who wants to see and feel their games at their absolute best, this monitor is a powerful and compelling upgrade. It delivers on its promise of providing a true next-generation gaming experience that will leave your old monitor in the dust.
If you’re ready to stop compromising and experience what your games are truly capable of, we wholeheartedly recommend the LG 27GX704A-B 27-inch OLED Gaming Monitor 240Hz. It’s an investment in immersion, performance, and pure gaming joy.
