Dahua LM27-E341AY 27" QHD IPS Gaming Monitor

The Dahua LM27-E341AY is a 27-inch QHD IPS gaming monitor engineered for competitive and enthusiast gamers who demand the highest achievable refresh rate at 2560×1440 resolution — without compromising on colour accuracy, visual quality, or display fidelity. Featuring a 275Hz high refresh rate, industry-leading 0.5ms OD response time, HDR10 support, 95% DCI-P3 wide colour gamut, Adaptive Sync, and dual DisplayPort 1.4 with dual HDMI inputs — the LM27-E341AY is the pinnacle of Dahua's QHD gaming monitor lineup and one of the fastest QHD IPS displays available at any price point.

QHD 2560×1440 — RESOLUTION AND SPEED WITHOUT COMPROMISE

The LM27-E341AY delivers 2560×1440 QHD resolution at 275Hz — a combination that eliminates the traditional trade-off between resolution and refresh rate that forces gamers to choose between a sharp 1440p image and a fast FHD display. At 27 inches, QHD achieves approximately 108 PPI pixel density — where individual pixels are imperceptible at normal viewing distances, producing a naturally crisp, detailed image across games, creative content, and professional applications. Every environment texture, UI element, and distant object is rendered with the clarity that FHD cannot deliver, while the 275Hz frame delivery speed ensures that clarity is maintained in full motion.

IPS PANEL — 95% DCI-P3, 178° VIEWING ANGLES, CONSISTENT COLOUR

The LM27-E341AY's IPS (In-Plane Switching) panel combines the colour accuracy and viewing angle consistency of professional display technology with the fast response times demanded by competitive gaming. 95% DCI-P3 wide colour gamut coverage reproduces a significantly broader range of colours than standard sRGB monitors — delivering deeper reds, more vibrant greens, and richer blues across game art, cinematic content, and creative projects with accuracy that meets professional post-production colour standards. IPS guarantees consistent colour reproduction across the full 178° horizontal and 178° vertical viewing cone — with no colour shift or contrast falloff at off-axis positions.

275Hz REFRESH RATE — THE FASTEST QHD IPS DISPLAY IN THE DAHUA LINEUP

At 275Hz, the LM27-E341AY refreshes 275 times per second at full 2560×1440 resolution — making it the highest refresh rate QHD monitor in the Dahua gaming range. The difference between 275Hz and 200Hz at QHD is perceptible: smoother character animation, sharper tracking during fast turns, reduced perceived input lag, and more fluid cursor movement during rapid mouse input. For competitive players who have already maximised their GPU performance at QHD, the 275Hz ceiling ensures the display is never the limiting factor in frame delivery.

0.5MS OD RESPONSE TIME — THE FASTEST PIXEL TRANSITION IN THE DAHUA RANGE

The 0.5ms OD (Overdrive) response time — measured as Moving Picture Response Time with overdrive enabled — is the fastest response specification in the Dahua gaming monitor lineup. At 0.5ms OD, pixel transitions complete in half a millisecond, eliminating all perceptible ghost trails, motion blur, and pixel smearing behind fast-moving objects at full 275Hz. For competitive FPS, battle royale, and racing titles where motion clarity is directly linked to target acquisition and reaction time, 0.5ms OD at 275Hz represents the current ceiling of IPS gaming display performance.

HDR10 — HIGH DYNAMIC RANGE SUPPORT

The LM27-E341AY supports the HDR10 standard, enabling display of high dynamic range content with expanded luminance range — producing brighter highlights, deeper shadows, and more nuanced midtone gradation compared to standard dynamic range (SDR) output. HDR10-compatible games, streaming content, and video files are displayed with the extended tonal range the LM27-E341AY's IPS panel and E-LED backlight can deliver — enhancing cinematic and immersive content beyond the SDR experience.

ADAPTIVE SYNC — ELIMINATE TEARING & STUTTERING AT QHD

Adaptive Sync technology dynamically synchronises the monitor's 275Hz refresh rate to the GPU's output frame rate in real time — eliminating screen tearing at QHD resolutions where GPU frame rates vary more significantly under load. Whether the GPU is producing 120fps during intensive scenes or 275fps in lighter environments, Adaptive Sync maintains smooth, tear-free frame delivery without the input latency penalty of traditional V-Sync — keeping QHD gaming consistently fluid across variable GPU load conditions.

300 cd/m² BRIGHTNESS — E-LED BACKLIGHT

The E-LED backlight delivers 300 cd/m² of typical brightness — maintaining clear, well-exposed visuals across gaming rooms and creative workspaces in standard ambient lighting conditions. HDR peak brightness extends beyond the SDR baseline for HDR10 content rendering.

HARDWARE-BASED ANTI-BLUE LIGHT & FLICKER-FREE

Hardware-level blue light filtering physically reduces high-energy blue light wavelength emission at the backlight — providing genuine blue light reduction without the colour temperature shift of software filters. Combined with hardware flicker-free technology, the LM27-E341AY eliminates imperceptible high-frequency backlight flickering that causes visual fatigue and headaches during extended gaming and creative sessions.

DUAL DisplayPort 1.4 + DUAL HDMI — QUAD-INPUT CONNECTIVITY

Four video inputs deliver maximum multi-source flexibility:

- 2x DisplayPort 1.4: Full 2560×1440 at 275Hz — for high-end gaming PCs and workstations

- 2x HDMI: High refresh rate QHD — for consoles, laptops, and secondary devices

Simultaneous quad-source connection enables full multi-device setups without cable swapping between sources.

TILT ADJUSTMENT & VESA 100x100mm MOUNT

The monitor stand supports tilt adjustment for comfortable viewing angle optimisation across desk heights and seating positions. The standard VESA 100x100mm mounting pattern accommodates any compatible monitor arm, wall bracket, or desk mount for placement flexibility beyond the included stand.

THREE-SIDED BORDERLESS DESIGN

The slim three-sided borderless bezel maximises screen presence within the monitor's physical footprint — delivering a cleaner, more immersive single-monitor experience and enabling tighter panel alignment in dual and multi-monitor configurations.
