LG 39-inch Ultragear evo 5K2K WUHD (5120 x 2160) OLED Curved Gaming Monitor, Black

Product Description:

The LG 39GX950B-B UltraGear evo is the world's first 39-inch 5K2K OLED gaming monitor — a groundbreaking display that combines the immersive ultrawide 21:9 format with a pixel-dense 5120 × 2160 resolution, LG's latest 4th Generation Primary RGB Tandem OLED panel technology, and a dual-mode refresh rate system that switches between 165Hz at full 5K2K resolution for stunning AAA gaming and 330Hz at WFHD for lightning-fast competitive play. With 143 pixels per inch, 0.03ms response time, 1500 nits peak brightness, and AI upscaling that enhances content to 5K2K without a GPU upgrade, the 39GX950B-B represents the pinnacle of ultrawide gaming display technology in 2026.

The 4th Generation Primary RGB Tandem OLED panel is LG Display's most advanced consumer OLED technology. The four-stack RGB structure doubles the light-emitting layers compared to standard OLED, delivering up to 335 cd/m² typical SDR brightness and 1500 nits peak HDR brightness — a dramatic improvement over previous OLED generations — while simultaneously improving power efficiency and panel longevity. Per-pixel light emission produces a staggering 1.85M:1 contrast ratio with true perfect blacks (UL-certified Perfect Black), meaning pixels that should be black are genuinely off — no glow, no backlight bleed, no zone dimming artifacts. Combined with 99.5% DCI-P3 color coverage and 10-bit color depth, every frame is rendered with absolute precision in color, contrast, and brightness.

The 5K2K resolution at 39 inches delivers 143 pixels per inch — 33% more total pixels than a 32-inch 4K display and dramatically sharper than the 3440 × 1440 resolution that previous 39-inch ultrawide OLEDs offered at just 96 PPI. This pixel density transforms in-game HUD elements, menu text, and fine details into crystal-clear, razor-sharp imagery, and makes the display equally exceptional for productivity tasks like coding, document editing, and creative work where text clarity is essential.

The VESA-certified Dual-Mode refresh rate system is a game-changer for versatility. At full 5K2K resolution, the display runs at 165Hz for gorgeous, detailed AAA gaming with smooth motion. Switch to WFHD (2560 × 1080) and the refresh rate doubles to 330Hz for competitive FPS, racing, and esports titles where frame rate and response time are more critical than resolution. The 0.03ms gray-to-gray response time virtually eliminates ghosting and motion blur in both modes. NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro ensure tear-free, low-latency adaptive sync with both major GPU ecosystems.

LG's built-in AI processor powers three intelligent features that operate independently of your GPU: AI Upscaling analyzes incoming content and enhances it toward the full 5K2K resolution in real time — meaning lower-resolution games and video look sharper without requiring a more powerful graphics card. AI Scene Optimization detects content type and automatically adjusts color temperature, sharpness, and enhancement settings. AI Sound separates voices, effects, and background audio to create a virtual 7.1.2-channel surround experience through the built-in dual 7W speakers or connected headphones.

Connectivity is future-proofed: DisplayPort 2.1 (UHBR20) delivers the bandwidth needed for 5K2K at 165Hz from a single cable, HDMI 2.1 supports next-gen consoles at 4K/120Hz, and USB-C with 90W Power Delivery provides single-cable laptop docking with display, data, and charging. The 1500R curvature wraps the 39-inch ultrawide display gently around your field of view for natural immersion without the aggressive distortion of tighter curves. The anti-glare low-reflection coating preserves OLED's deep blacks in ambient light. VESA DisplayHDR True Black 500 certification. Eyesafe 3.0, Flicker-Free, and Discomfort Glare Free certifications protect your eyes. OLED Care features help prevent burn-in. Tilt/height/swivel adjustable stand with VESA 100 × 100mm compatibility.
