Detects your space and delivers perfectly tuned audio through a simulated 9.1 channel setup, pinpointing sound locations for a tactical edge without the need for extra speakers or headsets. Also, it distinguishes the gamer's voice from ambient sound, adjusting voice levels and clarity to keep you focused on your game.
UltraWide view with deep black OLED
The 39-inch WQHD (3440x1440) display offers a 34% wider view than standard 16:9 screens, delivering sharp and clear visuals across the expansive display. While gaming in any setting, this WQHD OLED monitor displays bold and dark shadows, bright lighting and vibrant colours.
Brighter OLED
Experience stunning visuals with LG WOLED. Built on LG's OLED leadership and featuring Micro Lens Array+ (MLA+) technology, it delivers up to 37.5% brighter SDR, optimising light efficiency and minimising loss. It represents a standard luminosity of 275 nits (APL 100%) and a peak brightness of 1300 nits (APL 1.5%), ensuring vivid, true-to-life colours for immersive, precise gaming even in bright environments.
Go wide, not short.
The 21:9 UltraWide sweet spot for gaming
No more fisheye experience to see both sides of any 32:9 ratio panel at once. Thanks to the balanced and optimised aspect ratio, the 21:9 curved OLED monitor provides an immersive experience for both gaming and other forms of entertainment content.
The ideal curvature 800R
Immerse in the 800R curve designed to match natural sight, placing you at the core of its curvature. Dive into vivid, distortion-free graphics as you explore the gaming universe.
Deep black, realistic colour
Experience unparalleled depth and vibrant realism with VESA DisplayHDR true black 400, delivering detailed black expression even in the darkest scenes. With a 1.5M:1 contrast ratio, DCI-P3 98.5% (typical) colour gamut ensures that colours are displayed with realistic detail, just as originally intended.
Advanced anti-glare technology certified by triple UL
LG WOLED’s advanced anti-glare technology minimises frustrating reflections and distractions, delivering crystal-clear gaming performance by maintaining consistent clarity in any lighting. Additionally, with Triple UL certification for reducing harmful blue light while preserving vivid colour tones and lifelike visuals, it provides visual comfort and a smoother gaming experience—whether you’re gaming in bright environments or LED-lit rooms.
0.03ms (GtG) speed, 240Hz smooth gameplay
A swift 0.03ms (GtG) response and a rapid 240Hz refresh rate reduce reverse ghosting for crystal-clear, fluid visuals. Dive into more immersive gameplay with every frame.
Certified with widely utilised technologies
Powered by AMD FreeSync™ Premium, NVIDIA-validated G-SYNC® compatibility, and VESA AdaptiveSync™ certification, this monitor ensures tear-free, ultra-smooth visuals and low latency, delivering unmatched gaming precision and fluidity.
All-in-One USB-C for responsive gaming
Connect your laptop to the monitor with a USB-C cable for up to 65W power delivery, eliminating the need for a separate adapter. Enjoy WQHD resolution and a 240Hz refresh rate via DP 1.4 or HDMI 2.1, ensuring your gaming remains uninterrupted.
Optimise effortlessly with LG Switch
The LG Switch app optimises your monitor for both work and life. You can easily split the display into up to 11 options, change the theme design, or launch a video call platform with a mapped hotkey. Plus, you can quickly navigate and select smart functions with the keyboard and mouse, while seamlessly switching between your PC and webOS using shortcut keys.
