The Dahua DHI-LM27-EM331A is a 27-inch 2K QHD IPS gaming monitor designed for smooth, detailed visuals and comfortable everyday viewing. With a 2560x1440 resolution and a 200Hz refresh rate, it delivers crisp clarity for work and immersive performance for gaming and multimedia. The IPS panel helps maintain consistent image quality from wide viewing angles, making it a strong choice for both solo use and shared viewing in home offices or professional environments.
Featuring a 2560x1440 (2K QHD) display, this monitor provides more screen space and finer detail compared to standard FHD setups. Whether you’re editing documents, reviewing spreadsheets, designing content, or playing fast-paced games, the higher resolution helps reduce the “pixel crowding” effect and makes text and graphics appear more defined. The 16:9 widescreen aspect ratio is ideal for typical desktop workflows and most gaming titles.
The IPS panel type supports wide horizontal and vertical viewing angles of 178 degrees, so colors and contrast remain stable even when you’re not viewing straight-on. Dahua also includes eye-care features such as flicker-free technology and low blue light protection, which can be especially helpful for extended study, office work, or late-night gaming sessions. Compared to TN panels, IPS generally offers more consistent color and viewing comfort, which is beneficial for content-focused tasks.
With a refresh rate up to 200Hz and a 1ms (MPRT) response time, the Dahua DHI-LM27-EM331A is built to reduce motion blur and improve the smoothness of fast transitions. This combination is particularly useful for competitive gaming where frame pacing and responsiveness matter. If you’re coming from a lower refresh rate monitor, you’ll typically notice smoother scrolling, more fluid gameplay, and less perceived tearing during high-action scenes.
The monitor supports HDR 600, delivering ultra-bright highlights and deeper blacks for a more lifelike contrast experience. It is described as a 27-inch QHD 180 zones QD-MiniLED gaming monitor, using full-array local dimming with 180 zones to enhance HDR performance. In practical terms, this helps scenes with bright lights and dark shadows look more separated and detailed, which can improve the visual impact of HDR-supported games, movies, and creative work that benefits from stronger dynamic range.
For color-rich visuals, the display covers 98% DCI-P3 color gamut, supporting vivid and consistent colors for creative tasks and entertainment. The monitor is rated for 1.07 billion colors and includes color accuracy with AE<2, helping reduce noticeable color deviation across content. This makes it suitable for users who want more than basic office output—such as photo viewing, design previews, and media consumption where color quality matters.
Comfort and usability are supported by a rotatable lift base with height adjustment up to 110 mm (4.33 inch). You can rotate the screen by +90 degrees and swivel between -20 degrees and +20 degrees, while tilt adjustment is available from -5 degrees to 15 degrees. This range helps you position the monitor for better posture, reduce neck strain, and switch between landscape and portrait-style viewing when needed for coding, reading long documents, or reviewing vertical content.
The Dahua DHI-LM27-EM331A includes 2 x HDMI 2.1 and 1 x DisplayPort 1.4 for versatile device pairing. The HDMI ports support 2560 x 1440 at 144Hz, while the DisplayPort supports 2560 x 1440 at 200Hz—useful if you want the highest refresh rate for gaming on a compatible PC. An audio out (headphone jack) is provided for connecting external speakers or headphones, and the monitor supports VESA wall mounting with a 100 x 100 mm standard for clean desk setups.
The monitor’s power consumption is listed as 26W (basic), 32W (typ.), and 40W (max), with standby power consumption of <=0.5W. It uses a 19 VDC power supply (3.42A). For reliability, the product comes with a 3-year warranty (with the note that a box is mandatory while claiming). With a weight of 5.6 kg and dimensions of 614.5 x 363.8 x 73.5 mm, it’s designed to fit standard desktop and wall-mount environments.
In Bangladesh, the Dahua DHI-LM27-EM331A monitor price starts from 29,000. Pricing may vary based on availability and customization, and you can purchase through the website or nearby showrooms.
