LG 27G550B-B UltraGear™ G5 FHD 300Hz IPS | Height/Tilt/Pivot/Swievel Adjustable Stand, HDMI & DisplayPort- Gaming Monitor

The LG UltraGear G5 27G550B-B is a 27-inch Full HD IPS gaming monitor engineered for competitive esports players and fast-paced gaming who demand 300Hz fluid motion, 1ms GtG response time, and dual adaptive sync support — alongside a full-function ergonomic stand with height, tilt, swivel, and pivot adjustment, and LG's competitive gaming feature suite including Dynamic Action Sync, Black Stabilizer, and Crosshair overlay. With 99% sRGB colour coverage, HDR10 support, and a virtually borderless 3-side design — the 27G550B-B delivers the complete competitive gaming display experience at 27 inches.

300Hz REFRESH RATE — PUSH THE PACE

A blazing 300Hz refresh rate keeps fast action sharp and controlled. At 300Hz, the display refreshes 300 times per second — delivering the smoothest possible motion rendering for fast-paced gaming titles including FPS, battle royale, and esports. Track enemies, react faster, and stay locked into every frame with reduced motion blur and smoother, more responsive gameplay. The difference between 144Hz and 300Hz is perceptible in competitive play: faster character rendering, sharper tracking targets, and more fluid in-game motion that matches the reaction speed of experienced competitive players.

1ms RESPONSE TIME (GtG) — CRISP, GHOSTING-FREE GAMEPLAY

1ms Response Time (GtG) keeps fast-paced gameplay sharp by minimizing blur and ghosting. At 1ms GtG, pixel transitions complete in one millisecond — eliminating the ghost trails, motion smearing, and pixel trailing behind fast-moving in-game elements that slower panels produce at 300Hz. Whether tracking enemies, racing to the finish, or reacting to explosive action sequences, every frame stays crisp — giving competitive players the visual clarity needed for accurate target acquisition at maximum frame rates.

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

NVIDIA G-SYNC Compatible and AMD FreeSync Premium deliver smooth, tear-free, low-latency gaming with high refresh rates — so every frame stays fluid and sharp. Adaptive sync dynamically matches the monitor's 300Hz refresh rate to the GPU's output frame rate in real time — eliminating screen tearing caused by frame and refresh rate mismatches, and the micro-stuttering produced by V-Sync buffering. FreeSync Premium specifically requires a minimum 120Hz refresh rate at FHD resolution and Low Framerate Compensation (LFC) — delivering stutter-free output even when GPU frame rate drops significantly below the panel's maximum.

IPS DISPLAY — 99% sRGB, 178° VIEWING ANGLES, HDR10

Step onto the battlefield with HDR10 visuals and up to 99% sRGB colour gamut coverage. The IPS display delivers rich, vivid tones, so every explosion, environment, and character model is rendered with the accuracy and colour depth game developers intended. IPS panel technology maintains consistent colour accuracy and contrast across 178° horizontal and 178° vertical viewing angles — ensuring the image remains faithful from any seating position, including multi-player side-by-side gaming setups.

HDR10 support provides high dynamic range content rendering — expanding the luminance range beyond standard dynamic range with brighter highlights and deeper shadows in compatible HDR10 gaming titles and media.

DYNAMIC ACTION SYNC — REDUCED INPUT LAG

Dynamic Action Sync (DAS) reduces input lag for real-time, responsive gameplay by minimising the signal processing delay between GPU output and panel display — keeping on-screen action as closely synchronised to controller/mouse input as the display's hardware allows. DAS is particularly impactful in competitive FPS and battle royale titles where millisecond-level input responsiveness directly impacts player performance.

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 where enemy detection depends on shadow detail that standard gamma curves conceal. A targeted advantage for tactical shooters, survival games, and any title with dark in-game environments.

CROSSHAIR OVERLAY — FPS PRECISION AIM

Crosshair adds a centre-screen aim point overlay for better vision and accuracy in FPS games — providing a persistent reticle visible at all times regardless of in-game scope or iron sight availability. Configurable crosshair styles overlay on any game without requiring software modification.

FULL ERGONOMIC STAND — HEIGHT, TILT, SWIVEL, PIVOT

The full-function ergonomic stand provides complete positional flexibility:

- Height adjustment: position the panel at exact eye level for any desk height and seating combination

- Tilt: forward/backward tilt for comfortable viewing angle without neck strain

- Swivel: left/right rotation for desk orientation flexibility and shared viewing

- Pivot: 90° portrait rotation for vertical monitor configurations, coding workflows, and document reading

VIRTUALLY BORDERLESS 3-SIDE DESIGN

The virtually borderless 3-side bezel minimises the border on the top and both sides — maximising screen presence within the 27G550B-B's physical footprint and enabling tighter, more seamless alignment in dual and triple-monitor setups.

2x HDMI 2.0 + DisplayPort 1.4 — COMPREHENSIVE INPUT CONNECTIVITY

- 2x HDMI 2.0: supports up to 1920×1080 at 300Hz — for gaming PCs, laptops, and next-gen consoles

- 1x DisplayPort 1.4: supports up to 1920×1080 at 300Hz — for gaming PCs and workstations

- Dual HDMI inputs enable two simultaneous source connections — switch between a gaming PC and a console without cable changes

VESA 100×100mm — MONITOR ARM COMPATIBLE

Standard VESA 100×100mm mounting pattern accommodates any monitor arm, wall bracket, or desk mount for placement flexibility independent of the included ergonomic stand.
