Dahua LM27-E240A 27" FHD VA Gaming Monitor

The Dahua LM27-E240A is a 27-inch Full HD VA gaming monitor engineered for competitive and enthusiast gamers who demand ultra-high refresh rates, rapid response times, deep contrast, and premium connectivity in a single display. With a native 280Hz refresh rate overclockable to 300Hz, 1ms MPRT response time, AMD FreeSync Adaptive Sync, an 85% NTSC wide colour gamut, dual DisplayPort 1.4 and dual HDMI 2.1 inputs, and a fully ergonomic stand with height adjustment, swivel, tilt, and 0°–180° pivot — the LM27-E240A is the performance centrepiece of any serious gaming setup.

VA PANEL — 4000:1 CONTRAST, DEEP BLACKS, WIDE VIEWING ANGLES

The LM27-E240A is built around a VA (Vertical Alignment) panel — the preferred panel technology for gamers who prioritise contrast ratio and colour depth alongside high refresh rates. VA delivers a 4000:1 contrast ratio — four times deeper than typical IPS panels — producing true, rich blacks in dark gaming scenes, HDR content, and cinematic sequences that IPS cannot replicate at this price point. Combined with 178°/178° horizontal and vertical viewing angles, the VA panel maintains accurate colour and contrast from virtually any seating position, making it equally suited to solo and multiplayer gaming environments.

280Hz NATIVE / 300Hz OVERCLOCKED — ULTRA-FLUID COMPETITIVE GAMING

The LM27-E240A operates at a native 280Hz refresh rate — already among the highest available in the 27" FHD category — and can be overclocked to 300Hz for the absolute maximum frame delivery speed achievable at Full HD resolution. At 300Hz, the display refreshes 300 times per second, delivering smoother character movement, more precise target tracking, reduced perceived input lag, and a measurable competitive advantage in fast-paced titles including first-person shooters, battle royale, and tactical games. The difference between 280Hz and 300Hz is perceptible to trained competitive players; both are transformative upgrades over 144Hz displays.

1MS MPRT RESPONSE TIME — ZERO GHOSTING, ZERO TRAILING

The 1ms Moving Picture Response Time (MPRT) ensures that each displayed pixel transitions and clears within 1 millisecond — eliminating ghost trails, motion blur, and pixel trailing behind fast-moving objects at full 300Hz frame rates. At 300Hz with 1ms MPRT, every frame is sharp, clean, and artefact-free — the response standard demanded by esports professionals and competitive players who cannot afford visual compromise during critical gameplay moments.

AMD FREESYNC ADAPTIVE SYNC — ELIMINATE TEARING & STUTTERING

The LM27-E240A supports AMD FreeSync Adaptive Sync technology, dynamically synchronising the monitor's refresh rate to the output frame rate of a compatible GPU in real time. When GPU frame rate fluctuates — during intensive scenes, shader-heavy environments, or variable-load gameplay — FreeSync eliminates the screen tearing produced by mismatched frame and refresh rates, and the micro-stuttering produced by V-Sync buffering. The result is a consistently smooth, tear-free image across the full operating refresh range without the input latency penalty of traditional V-Sync.

85% NTSC WIDE COLOUR GAMUT — VIVID, ACCURATE COLOUR REPRODUCTION

The LM27-E240A covers 85% of the NTSC colour gamut — delivering noticeably more vivid, saturated colour reproduction than standard sRGB monitors, with accurate rendering of game art, cinematic content, and digital design assets. Deep reds, rich blues, and vibrant greens are reproduced with intensity and accuracy that standard gamut displays cannot match — enhancing the visual impact of every title without colour oversaturation.

300 cd/m² BRIGHTNESS — E-LED BACKLIGHT

The E-LED backlight delivers 300 cd/m² typical brightness — 20% higher than the LM27-A221Y — maintaining clear, well-exposed visuals in brightly lit gaming rooms and shared spaces without requiring room darkening for comfortable viewing.

BLACK EQUALIZER — VISIBILITY IN DARK ENVIRONMENTS

The Black Equalizer feature 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.

GAME MODES — GENRE-OPTIMISED DISPLAY PROFILES

Multiple preset game modes optimise display parameters — brightness, contrast, colour temperature, and sharpness — for specific gaming genres including FPS, RTS, and general gaming, enabling instant display profile switching matched to the current title.

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

Four video inputs provide maximum device compatibility and multi-source flexibility:

- 2x DisplayPort 1.4: Full 1920x1080 at 300Hz — for high-end gaming PCs and workstations

- 2x HDMI 2.1: Full 1920x1080 at 300Hz — for gaming consoles (PS5, Xbox Series X), laptops, and secondary PCs

Dual inputs of each type enable seamless switching between a gaming PC, a console, a streaming PC, and a secondary device — all connected simultaneously without cable swapping.

FULLY ERGONOMIC STAND — HEIGHT, TILT, SWIVEL & PIVOT

Unlike budget gaming monitors with tilt-only stands, the LM27-E240A ships with a fully articulated ergonomic stand offering:

- Height Adjustment: 100mm ± 5mm range for precise desk-height optimisation

- Tilt: -5° (±2°) to +15° (±2°) for comfortable viewing angle without neck strain

- Swivel: ±20° horizontal rotation for shared viewing and multi-position setups

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

VESA 100x100mm WALL MOUNT

Standard VESA 100x100mm mounting pattern supports any compatible monitor arm, wall bracket, or desk mount for flexible placement beyond the included stand.

FLICKER-FREE & LOW BLUE LIGHT — EYE CARE FOR EXTENDED SESSIONS

Flicker-free backlight technology eliminates imperceptible high-frequency screen flickering that causes eye fatigue and headaches during long sessions. Low Blue Light mode filters high-energy blue light wavelengths to reduce eye strain and discomfort during extended gameplay, study, and work use.
