LG 27G523B-B G5 27" UltraGear™ " FHD 200Hz IPS sRGB 99%, HDR10, 1ms GtG, G‑SYNC Compatible, FreeSync Premium, Tilt Adjustable Stand, HDMI & DisplayPort– Gaming Monitor

The LG UltraGear G5 27G523B-B is a 27-inch Full HD IPS gaming monitor engineered for competitive and enthusiast gamers who want a 200Hz high-refresh display with 1ms GtG response, dual adaptive sync, and LG's full gaming feature suite — Dynamic Action Sync, Black Stabilizer, and Crosshair overlay — in a 27-inch form factor with 3-side virtually borderless design and clutter-free L-Stand. Sharing the same IPS panel, 99% sRGB, HDR10, and G-Sync + FreeSync Premium as the 25G523B-B — but adding LG's competitive gaming tools and a larger 27-inch canvas — the 27G523B-B is the more complete gaming display in the G5 lineup.

27" FHD IPS — 99% sRGB, 1000:1 CONTRAST, 178° VIEWING ANGLES

The 27-inch Full HD (1920×1080) IPS display delivers vivid colour accuracy across 99% sRGB coverage with 1000:1 contrast and consistent image quality from 178° horizontal and 178° vertical viewing angles. At 27 inches, the FHD resolution provides a larger, more immersive gaming canvas than the 25" model — better suited for gaming environments where screen real estate matters alongside refresh rate and response performance.

200Hz REFRESH RATE — SMOOTH COMPETITIVE GAMING

At 200Hz, the 27G523B-B refreshes 200 times per second — delivering meaningfully smoother motion than 144Hz and 165Hz panels for fast-paced competitive titles. Character tracking, projectile motion, camera pans, and environmental detail all render with greater fluidity at 200Hz — enabling more precise visual processing and faster reaction in competitive FPS, battle royale, and esports titles.

1ms RESPONSE TIME (GtG) — SHARP AT 200Hz

The 1ms GtG response time ensures pixel transitions complete within 1 millisecond — eliminating ghost trails, motion smearing, and pixel trailing at 200Hz. Fast-moving in-game elements remain sharp and artefact-free across the monitor's full 200Hz operating range.

DYNAMIC ACTION SYNC — REDUCED INPUT LAG

Dynamic Action Sync (DAS) minimises the signal processing delay between GPU output and on-screen display — reducing input lag for real-time, responsive gameplay. DAS keeps on-screen action as closely synchronised to controller and mouse input as possible, delivering the competitive responsiveness advantage that millisecond-level input timing provides in fast-paced titles.

BLACK STABILIZER — TACTICAL VISIBILITY IN DARK SCENES

Black Stabilizer intelligently brightens dark areas of the game image without overexposing bright areas — improving visibility in shadowed environments, dark corridors, night maps, and stealth scenes. Enemy positions and environmental details hidden in dark game areas become clearer, providing a competitive tactical advantage in shooters, survival games, and any title with dark in-game environments.

CROSSHAIR OVERLAY — FPS PRECISION AIM

Crosshair adds a persistent centre-screen aim point overlay — providing a visible reticle at all times regardless of in-game scope, iron sights, or weapon configuration. Configurable crosshair styles overlay on any game without software modification, giving FPS players a consistent aiming reference across every title and every playstyle.

G-SYNC COMPATIBLE + AMD FREESYNC PREMIUM — DUAL ADAPTIVE SYNC

NVIDIA G-Sync Compatible and AMD FreeSync Premium certify the 27G523B-B for tear-free, stutter-free gaming with compatible GPUs from both manufacturers. Adaptive sync dynamically synchronises the monitor's 200Hz refresh rate to the GPU's output frame rate — eliminating screen tearing and V-Sync stuttering. FreeSync Premium certification requires minimum 120Hz at FHD and Low Framerate Compensation — maintaining smooth output even when GPU frame rate drops below the panel's maximum.

HDR10 — HIGH DYNAMIC RANGE CONTENT SUPPORT

HDR10 compatibility enables enhanced contrast and brightness handling across supported content — brighter highlights and deeper shadows in HDR10-enabled games, streaming services, and media for more dynamic, immersive visual depth.

300 cd/m² BRIGHTNESS — CLEAR IN GAMING ENVIRONMENTS

300 cd/m² typical brightness maintains clear, well-exposed visuals in gaming rooms and home office environments under standard ambient lighting.

3-SIDE VIRTUALLY BORDERLESS + L-STAND

The 3-side virtually borderless bezel maximises screen presence and enables tighter dual-monitor alignment. The clutter-free L-Stand minimises desk space usage, keeping the area around the monitor open and organised.
