For years, the quest for the ultimate gaming monitor felt like chasing a mirage. High refresh rates sacrificed resolution. High resolution sacrificed speed. Stunning visuals often meant sacrificing immersion. Enter the LG 45GX950A-B Ultragear, a colossal 45-inch curved OLED behemoth promising to shatter those compromises. After weeks living with this 5K2K titan, I'm both exhilarated and contemplative – this monitor is a breathtaking technological achievement, but one that demands careful consideration.
First Impressions: A Curved Canvas of Wonder
Unboxing the 45GX950A-B is an event. Its sheer scale is immediately imposing. The 800R curvature – one of the most aggressive on the market – feels purposeful, designed to envelop your peripheral vision completely. The build quality is classic LG Ultragear: premium plastics, a robust stand with height, tilt, and swivel adjustments (though no pivot on a screen this size!), and a surprisingly sleek profile for such a large OLED. Setting it up requires a deep desk (seriously, check your depth!) and a sturdy mount if you forego the included stand. Once powered on, however, any logistical concerns momentarily vanish. The OLED panel ignites with that signature infinite contrast – inky blacks that melt into the bezel and vibrant, almost unnervingly bright highlights.
The OLED Advantage: Where the Magic Happens
This is where the 45GX950A-B truly justifies its premium positioning. LG's WOLED technology delivers everything we love about OLED for gaming:
- Pixel-Perfect Contrast: Absolute blacks mean unparalleled depth and realism. Scenes in dark games like Alan Wake 2 or Hollow Knight are genuinely atmospheric, with details emerging from true darkness. No more IPS glow or VA smearing to muddy the shadows.
- Blazing Fast Response: Near-instantaneous pixel response times (0.03ms GtG) obliterate ghosting and motion blur. Fast-paced shooters (*Counter-Strike 2*, Apex Legends) and racing games (Forza Horizon 5) feel incredibly sharp and fluid. Combined with the high refresh rate, motion clarity is exceptional.
- Vibrant, Accurate Colors: Covering 98.5% of the DCI-P3 gamut, colors pop with intensity and nuance. HDR content (Dolby Vision, HDR10, HLG) is a revelation. Highlights in sunlit scenes or explosions retain stunning detail without washing out, while the deep blacks provide the necessary foundation. LG's factory calibration is also impressively accurate out of the box for an entertainment-focused display.
5K2K (5120x2160): The Ultra-Wide Sweet Spot?
The 45GX950A-B boasts a "5K2K" resolution – essentially 4K (3840x2160) extended wider to 5120x2160. This 21:9 aspect ratio is the darling of immersive gaming and productivity. In games that support it natively (and most modern AAA titles do), the experience is transformative. The expanded field of view gives you a tactical advantage and makes expansive worlds feel truly vast. Flying through Microsoft Flight Simulator or exploring the landscapes of Horizon Forbidden West becomes significantly more engaging.
However, the resolution brings a crucial consideration: Pixel Density (PPI). At 45 inches, the PPI sits around 110. Compared to a 27-inch 4K monitor (163 PPI) or even LG's own 34-inch 3440x1440 Ultrawides (~110 PPI but smaller), text and fine desktop details can appear slightly less sharp, especially if you're used to high-PPI displays. It's not "blurry" by any stretch, but it lacks the razor-sharpness of denser panels. For pure gaming immersion, it's rarely an issue. For long hours of text-based work or intricate photo editing, it might require some adjustment or scaling (Windows/MacOS scaling works well).
Gaming Prowess: Speed Meets Splendor
This is an LG Ultragear, so gaming is its core DNA:
- 240Hz Refresh Rate: Buttery-smooth gameplay is delivered. Paired with the OLED response times, it creates an incredibly lifelike and responsive feel, crucial for competitive titles.
- VRR (FreeSync Premium Pro & G-SYNC Compatible): Tear-free, stutter-free gaming is assured across NVIDIA and AMD GPUs. The wide refresh range handles frame rate dips seamlessly.
- HDMI 2.1 x 2, DisplayPort 1.4: Supports the full bandwidth needed for 5120x2160 at high refresh rates (with DSC - Display Stream Compression) and next-gen consoles (though the 45" size and 21:9 aspect ratio are less ideal for console use than 16:9 TVs).
- Game Optimizer & Black Stabilizer: LG's suite of gaming tools is present and useful, allowing quick access to presets, crosshairs, FPS counters, and settings to improve visibility in dark scenes.
The combination of the massive, curved screen, flawless motion handling, stunning HDR, and high refresh rate creates an unparalleled sense of immersion. You don't just play the game; you feel enveloped by it.
Everyday Use and Quirks
Beyond gaming, the 45GX950A-B is a compelling, if specialized, productivity monitor. The 21:9 aspect ratio is fantastic for multitasking – comfortably fitting three full-sized windows side-by-side. The curve aids visibility across the vast expanse. However, the PPI limitation for text and the sheer physical size require a significant adjustment period and a deep desk.
OLEDs also come with inherent considerations:
- ABL (Automatic Brightness Limiter): On large, bright white screens (like documents or web pages), the monitor can dim the entire screen to manage power/heat. It's noticeable but less aggressive than some OLED TVs.
- ASBL (Automatic Static Brightness Limiter): Dims static elements over time to prevent burn-in. Can sometimes be intrusive in very static productivity scenarios (e.g., coding with a bright IDE for hours).
- Burn-in Mitigation: LG includes robust features like pixel shifting, screen savers, and a logo dimmer. While burn-in risk is lower than early OLEDs and covered under warranty, it requires mindful usage habits (varying content, using screen savers, avoiding static bright UIs for days on end). This is crucial to understand before investing.
- Reflections: The glossy screen offers incredible clarity but is very reflective. A controlled lighting environment is essential.

Verdict: A Niche Masterpiece
The LG 45GX950A-B Ultragear is not just a monitor; it's an experience. It delivers the most immersive, visually stunning, and responsive gaming experience I've ever had on a desktop display. The combination of massive curved OLED, 5K2K resolution, 240Hz, and flawless motion is simply unmatched for drawing you into the game world.
However, it's not for everyone. The size demands space and a deep desk. The PPI, while sufficient for gaming, might disappoint those prioritizing razor-sharp text for work. OLED's inherent characteristics (ABL/ASBL, burn-in mitigation requiring user awareness, reflections) necessitate an informed buyer who understands and accepts the trade-offs.
Who is it for? The hardcore gamer seeking the ultimate immersion, willing to invest in a premium setup and manage OLED's quirks. The sim racer or flight enthusiast craving expansive views. The multimedia enthusiast who prioritizes stunning HDR movies and content consumption alongside gaming.
Who should look elsewhere? Those needing pixel-perfect sharpness for extensive text work or detailed creative tasks. Users with very bright, uncontrolled rooms. Anyone deeply concerned about OLED longevity without diligent usage habits. Those on a tighter budget.
The Bottom Line: The LG 45GX950A-B is a technological tour-de-force. It achieves a level of gaming immersion that borders on the transcendent. If your primary goal is the most breathtaking, responsive, and enveloping gaming experience possible, and you have the space, setup, and understanding to embrace its OLED nature, it is an extraordinary, almost magical display. Just go in with your eyes wide open to its unique demands. For those ready to take the plunge, it represents the bleeding edge of gaming monitor technology.
