Description
Discover a new level of immersion with the 39-inch 5K2K (5120×2160) display. Designed in a 21:9 UltraWide format with a 1500R curved screen, offering about 33% more pixels than a 32-inch 4K display, it gently surrounds your vision to create a more immersive viewing experience. The high-density 5K2K resolution delivers crisp detail and visual depth, keeping every scene sharp, focused, and deeply engaging across a variety of games.
World’s first 5K2K AI Upscaling. No GPU upgrade required.*UltraGear evo™’s built-in processor powers 5K2K AI Upscaling, intelligently enhancing content to 5K2K resolution from any device. Without additional GPU or hardware upgrades, it intelligently upscales content to deliver sharper detail and improved resolution.**
4th Gen Tandem OLED.
Ultra-high 1500nits brightness.*Powered by 4th Gen Tandem OLED, LG 39GX950B delivers brighter visuals—reaching up to 1500 nits of peak brightness for visibly clearer gameplay, helping you to see on-screen visuals with precision even in bright environments.
Bright highlights and clear detail in the darknessExperience greater depth and vibrant realism with VESA DisplayHDR™ True Black 500, enhancing contrast to reveal bright highlights and refined shadow detail in games. Bright, high-impact effects appear more vivid and clearly defined, while dark scenes retain texture and clarity without losing detail. With DCI-P3 99.5% (Typ.) colour gamut, the monitor ensures that colours are displayed with realistic detail, as close to the original intent as possible.
High 143 PPI clarity for both gaming & productivity With a 143 PPI (Pixels Per Inch), it delivers a precise gaming experience and better productivity. During gameplay, in-game texts, UI elements, and fine details appear clearer and well-defined, making HUDs (Head-Up Displays), menus, and on-screen information easier to read. It also enhances clarity for text-heavy tasks such as document editing, web browsing, or coding.
Less eye strain
with UL-verified eye comfort tech LG UltraGear's UL-verified advanced eye comfort technologies minimize frustrating reflections and are designed with visual comfort in mind, delivering crystal-clear gaming performance with consistent clarity. With UL verifications in key areas—reducing screen flicker, minimizing discomfort glare—these technologies promote visual comfort and contribute to a smoother gaming experience, whether you’re gaming in bright environments or LED-lit rooms.
Maximise productivity with an expanded 5K2K UltraWide canvasUltraGear isn’t just for gaming — its expansive 5K2K resolution with 143 PPI delivers sharp, detailed visuals that are ideal for creators and multitaskers alike. While a typical 16:9 dual or triple monitor setup can lead to interruptions in your view due to bezels between displays, a wider 21:9 aspect ratio allows you to manage your entire workflow on a single screen. Whether you're retouching photos, editing videos, or searching for references, everything stays visible.
Optimised refresh rates for every genre with Dual-ModeSeamlessly match your game type with the ideal refresh rate using VESA Certified Dual-Mode—simply switch from 165Hz at 5K2K for AAA titles such as RPG and adventure to 330Hz at WFHD for fast-paced games like FPS and racing.
0.03ms (GtG). Quick response for gameplay.The 0.03ms (GtG) response time is built to reduce ghosting, helping maintain clearer on-screen transitions for smoother, more responsive gameplay.
Smooth motion that keeps you immersedMinimise tears and lags with NVIDIA® G-SYNC® compatible and AMD FreeSync™ Premium Pro technology. Experience significantly reduced screen tearing and stuttering for smooth visuals with minimised motion blur and ghosting.

Through 7W×2 built-in stereo speakers or headphones, voices remain clear even in intense firefights, while critical cues like approaching footsteps stay easy to detect during gameplay.
