Dahua LM27-E331Y 27" QHD IPS Gaming Monitor

The Dahua LM27-E331Y is a 27-inch QHD IPS gaming monitor engineered for gamers, creative professionals, and content creators who demand the resolution clarity of 2560×1440, a 200Hz high refresh rate, 1ms MPRT response time, and wide colour gamut accuracy — all in a single display with premium quad-input connectivity and a fully articulated ergonomic stand. Positioned at the intersection of competitive gaming performance and creative colour fidelity, the LM27-E331Y delivers where both audiences are uncompromising.

QHD 2560×1440 RESOLUTION — 78% MORE PIXELS THAN FHD

The LM27-E331Y's 2560×1440 QHD resolution renders 3.69 million pixels — 78% more than a 1920×1080 Full HD display — producing noticeably sharper, more detailed visuals across every type of content. At 27 inches, QHD achieves a pixel density of approximately 108 PPI, where individual pixels become imperceptible at normal viewing distances, creating a naturally crisp image without display scaling. Fine environmental detail, weapon textures, map edges, and UI elements in games are all rendered with clarity that FHD cannot replicate. For creative work — photo editing, video production, graphic design, and digital illustration — QHD provides a substantially larger working canvas with higher on-screen fidelity.

IPS PANEL — 178° VIEWING ANGLES, CONSISTENT COLOUR ACCURACY

The LM27-E331Y's IPS (In-Plane Switching) panel technology ensures consistent, accurate colour reproduction across the full 178° horizontal and 178° vertical viewing cone — with no colour shift, contrast loss, or hue deviation at off-axis viewing angles. IPS delivers reliable colour fidelity that makes it the preferred panel technology for creative professionals and colour-accurate workflows, while still delivering fast response times suitable for competitive gaming. The IPS panel's 1000:1 contrast ratio provides clear separation between light and dark content across the full QHD resolution.

200Hz HIGH REFRESH RATE — FLUID QHD GAMING

At 200Hz, the LM27-E331Y refreshes 200 times per second at full 2560×1440 QHD resolution — delivering significantly smoother motion, sharper moving imagery, and more responsive cursor and character movement than standard 144Hz and 165Hz QHD displays. The 200Hz refresh rate at QHD represents the optimal balance between visual resolution and frame delivery speed — providing competitive gaming performance without the resolution compromise of FHD-only high-refresh displays. Fast-paced games, cinematic animations, and rapid camera movements all benefit immediately from the increased refresh cadence.

1MS MPRT RESPONSE TIME — SHARP MOTION AT 200Hz

The 1ms Moving Picture Response Time (MPRT) ensures pixel transitions complete within 1 millisecond, eliminating ghost trails, motion blur, and pixel smearing at the LM27-E331Y's full 200Hz refresh rate. At 200Hz with 1ms MPRT, every frame is rendered cleanly without trailing artefacts — critical for accurate target tracking and fast-action clarity in competitive titles where motion sharpness directly impacts performance.

WIDE COLOUR GAMUT — 95% DCI-P3 COVERAGE

The LM27-E331Y covers 95% of the DCI-P3 colour space — the professional digital cinema colour standard used in film production, post-production, and professional display calibration. At 95% DCI-P3, the monitor reproduces a significantly wider range of colours than standard sRGB displays, delivering richer reds, deeper blues, and more vibrant greens across games, video content, and creative projects. For photographers, videographers, and digital artists, DCI-P3 coverage at this level provides reliable professional colour accuracy without requiring an external calibration device.

300 cd/m² BRIGHTNESS — E-LED BACKLIGHT

The E-LED backlight delivers 300 cd/m² of typical brightness — maintaining clear, well-exposed visuals in ambient lighting conditions across gaming rooms, studios, and office environments. Consistent brightness distribution across the IPS panel surface ensures uniform illumination without hotspots or brightness falloff at panel edges.

HARDWARE-BASED ANTI-BLUE LIGHT & FLICKER-FREE TECHNOLOGY

The LM27-E331Y implements hardware-level anti-blue light filtering — a physical reduction of blue light wavelength emission at the backlight level, rather than a software colour profile applied post-display. Hardware anti-blue light provides genuine blue light reduction without the yellow-tint colour shift of software-based filters, preserving colour accuracy while protecting against eye fatigue during extended gaming, design, and productivity sessions. Combined with hardware flicker-free backlight technology, the LM27-E331Y eliminates the imperceptible high-frequency screen flickering that causes headaches and visual fatigue across prolonged use.

ADAPTIVE SYNC — ELIMINATE TEARING & STUTTERING

Adaptive Sync technology dynamically matches the monitor's refresh rate to the GPU's output frame rate in real time — eliminating screen tearing caused by refresh/frame rate mismatches and the micro-stuttering produced by V-Sync latency. The result is consistent, smooth, tear-free frame delivery across the full operating refresh range during GPU-intensive QHD gaming scenes.

DUAL DisplayPort 1.4 + DUAL HDMI 2.1 — QUAD-INPUT CONNECTIVITY

Four video inputs deliver maximum device compatibility for complex multi-source setups:

- 2x DisplayPort 1.4: Full 2560×1440 at 200Hz — for gaming PCs and workstations

- 2x HDMI 2.1: Full 2560×1440 high refresh rate — for consoles, laptops, and secondary systems

Dual inputs of each type allow simultaneous connection of a gaming PC, a console, a work laptop, and a secondary device — with source switching via OSD without cable changes.

FULLY ERGONOMIC STAND — HEIGHT, TILT, SWIVEL & PIVOT

The LM27-E331Y ships with a fully articulated commercial-grade ergonomic stand delivering complete positional flexibility:

- Height Adjustment: 100mm range for precise desk-height and eye-level optimisation

- Tilt: -5° to +15° for comfortable viewing angle without neck or shoulder strain

- Swivel: ±20° horizontal rotation for shared viewing and angled desk setups

- Pivot: 0°–180° portrait rotation for vertical monitor configurations, coding workflows, and document reading

VESA 100x100mm WALL MOUNT

Standard VESA 100x100mm mount compatibility supports any monitor arm, wall bracket, or desk mount for placement flexibility independent of the included stand.

THREE-SIDED FRAMELESS BORDERLESS DESIGN

The three-sided frameless bezel design minimises border width on the top and both sides — maximising screen presence within the monitor's physical footprint and enabling tighter, more seamless alignment in dual and triple monitor configurations.
