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.

  1. 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.

  2. Triple Perfect Visuals verified by UL, even in bright light


    Perfect Black is UL-verified and delivers perfect black levels to enhance perceived brightness and contrast, whether it’s bright or dark around you.

    Perfect Colour and 100% Colour Fidelity deliver accurate colour expression even under varying lighting conditions, from low light to bright ambient environments.

Bright, high-impact effects appear more vivid and clearly defined, while dark scenes retain texture and clarity without losing detail.

  1. 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.

    Text reads "QUEST COMPLETE" with "70 PPI" and "143 PPI" badges. Comparison image showing red-tinted gaming/combat scene split screen, demonstrating resolution differences. Lower text references design awards and user experience.

    UltraGear 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.

  3. 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, minimising 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.
