LG 27GM950B-B 27" Ultragear evo AI GM9 Mini-LED IPS 5K 165Hz - Gaming Monitor

The LG UltraGear Evo 27GM950B-B is LG's flagship 27-inch gaming monitor — the world's first gaming monitor with 5K AI Upscaling, built on Hyper Mini LED IPS panel technology with 5K (5120×2880) resolution at 218 PPI, Dual Mode switching between 5K@165Hz and QHD@330Hz, VESA DisplayHDR 1000 with 1,250 nits peak brightness, 99% DCI-P3 colour coverage, AI Scene Optimization, AI Sound, DisplayPort 2.1, dual HDMI 2.1, USB-C 90W PD, full ergonomic stand, and built-in speakers. This is the definitive premium gaming and productivity display — engineered for gamers who refuse to compromise between resolution, refresh rate, brightness, and colour accuracy.

HYPER MINI LED IPS — NEXT-GENERATION BACKLIGHT TECHNOLOGY

The 27GM950B-B's Hyper Mini LED IPS panel uses the next generation of Mini LED backlight technology — tens of thousands of ultra-small LED dimming zones behind the IPS panel that allow independent brightness and dimming control across the panel surface. Hyper Mini LED achieves what standard LED IPS cannot: near-zero blooming, zero optic distance between the LEDs and the IPS layer, and a 1,250 nit peak brightness while maintaining IPS accuracy and 178°/178° wide viewing angles. The result is a monitor that delivers OLED-quality HDR contrast without OLED's burn-in risk and with significantly higher peak brightness than any consumer OLED panel.

5K RESOLUTION — 5120×2880, 218 PPI, UNPRECEDENTED CLARITY

5K (5120×2880) resolution on a 27-inch IPS panel achieves 218 PPI — the highest pixel density available in a 27-inch gaming monitor. At 218 PPI, individual pixels are completely imperceptible at normal viewing distances — rendering text, game assets, environmental textures, UI elements, and creative content with crystalline sharpness that 4K (163 PPI) and QHD (108 PPI) cannot match. Compared to FHD (1920×1080), 5K delivers approximately 8× the pixel count — transforming every game's visual fidelity from broad strokes to pinpoint detail.

5K AI UPSCALING — THE WORLD'S FIRST

UltraGear evo's built-in processor powers 5K AI Upscaling — intelligently upscaling content from any source to 5K resolution without requiring a GPU upgrade or additional hardware. Standard 4K, QHD, and FHD content from any connected device is processed through the AI upscaling engine and rendered at the panel's native 5K resolution — delivering sharper detail, improved edge definition, and enhanced texture clarity from existing content without any GPU-side processing cost. The 27GM950B-B is the world's first gaming monitor to support AI upscaling to 5K resolution.

DUAL MODE — 5K@165Hz OR QHD@330Hz, ON DEMAND

The 27GM950B-B's Dual Mode allows instant switching between two distinct operating configurations:

- 5K Mode (5120×2880 @ 165Hz): maximum resolution for AAA gaming, creative work, productivity, and content that benefits from 218 PPI visual clarity

- QHD Mode (2560×1440 @ 330Hz): maximum refresh rate for competitive esports, FPS titles, and any scenario where 330Hz frame delivery takes priority over resolution

Dual Mode means the 27GM950B-B is not a single-use gaming display — it adapts between premium visual experience mode and maximum competitive performance mode at the push of a button, covering both use cases without requiring a second monitor.

VESA DISPLAYHDR 1000 — 1,250 NITS PEAK, TRUE HDR

VESA DisplayHDR 1000 is the certification standard that defines true premium HDR performance — requiring sustained 600 cd/m² and peak 1,000+ cd/m² brightness across a significant portion of the panel area. The 27GM950B-B achieves 750 cd/m² typical brightness, 1,250 nits peak brightness, and Hyper Mini LED's granular zone dimming for deep, precise dark scene rendering. HDR content in certified games, films, and streaming services is displayed with the luminance range, shadow detail, and highlight intensity the 27GM950B-B's HDR grade was designed to deliver — not approximated from a 300 nit SDR panel with a software HDR mode.

99% DCI-P3 COLOUR COVERAGE — PROFESSIONAL CREATIVE ACCURACY

99% DCI-P3 coverage provides professional digital cinema colour fidelity — the colour standard used in film post-production and cinema projection. Every game asset, photograph, video, and creative project is rendered with the full DCI-P3 colour range intended by its creator. For photographers, videographers, and digital artists using the 27GM950B-B as a professional display alongside gaming, 99% DCI-P3 provides colour accuracy that rival professional-grade display monitors — without requiring a separate creative display.

AI SCENE OPTIMIZATION — INTELLIGENT CONTENT DETECTION

AI Scene Optimization uses artificial intelligence to detect the type of content currently displayed — gaming, movie, sports, or general use — and automatically adjusts display parameters including brightness, colour temperature, and contrast to the optimal profile for that content type. Manual mode switching between SDR gaming and HDR movie content, for example, is handled automatically without OSD navigation.

AI SOUND — ENHANCED AUDIO PROCESSING

AI Sound enhances voice clarity, key audio cues, and spatial audio positioning through AI-powered sound processing — improving the built-in speaker audio quality for gaming scenarios where directional audio, voice chat, and environmental sound cues matter. AI Sound applies dynamic audio enhancement that adapts to content type alongside AI Scene Optimization.

DYNAMIC ACTION SYNC + BLACK STABILIZER + CROSSHAIR

- Dynamic Action Sync (DAS): reduces input lag for real-time responsiveness — the minimum signal processing delay between GPU output and on-screen display

- Black Stabilizer: brightens dark areas without overexposing bright areas — improving tactical visibility in shadow-heavy gaming environments

- Crosshair: persistent centre-screen aim point overlay for FPS precision — configurable styles across all games

DISPLAYPORT 2.1 — 5K@165Hz BANDWIDTH

The DisplayPort 2.1 port provides the full bandwidth required to drive 5K resolution at 165Hz — a technical requirement that DisplayPort 1.4 cannot satisfy for true 5K@165Hz transmission. DisplayPort 2.1 is the future-ready display interface standard — backwards compatible with DP 1.4 sources while providing headroom for next-generation GPU output.

DUAL HDMI 2.1 + USB-C 90W PD

- 2x HDMI 2.1: QHD or FHD at high refresh rates — for consoles (PS5, Xbox Series X at QHD/330Hz mode) and secondary PCs

- 1x USB-C (90W Power Delivery): single-cable MacBook, laptop, and mobile device connection delivering display signal and 90W charging simultaneously

FULL ERGONOMIC STAND — HEIGHT, TILT, SWIVEL, PIVOT

The full-function ergonomic stand supports height adjustment, tilt, swivel, and 90° pivot for portrait mode — enabling complete positional flexibility across desk heights, monitor arm configurations, and vertical display orientations for productivity and creative workflows.
