27" Dahua LM27-E331Y
The Dahua LM27-E331Y gaming monitor delivers detailed Quad HD 2560×1440 resolution on its 27" screen. This QHD monitor uses IPS technology, which provides wide 178° viewing angles and accurate colour reproduction. A key feature is the very high 200Hz refresh rate, which, combined with the 1ms (MPRT) response time, reduces motion blur and image ghosting. This 200Hz monitor therefore displays fast action with high sharpness. The colour spectrum covers 95% of the DCI-P3 space with an accuracy of ΔE<2 and the panel displays up to 1.07 billion colours. HDR 10 support further deepens contrast, while Flicker-free technology and hardware blue light protection reduce eye strain during prolonged use.

Image Performance
The foundation of the image is a 27" IPS panel with a fine Quad HD 2560×1440 pixel resolution, which provides sharp details over a spacious area. IPS technology delivers wide 178° viewing angles both vertically and horizontally, so colours remain consistent even when viewed from the side. The monitor displays 1.07 billion colours, which contributes to smooth colour gradients. The colour spectrum covers 95% of the DCI-P3 space with a high accuracy of ΔE<2. The matte finish with 3H hardness effectively suppresses reflections from surrounding light sources.
Speed and Smoothness for Gaming
The main advantage of this monitor is its speed, tailored for competitive gaming. The very high 200Hz refresh rate renders motion with high fluidity, giving gamers an edge in fast-paced action titles. This rate is complemented by a 1ms (MPRT) response time, which significantly reduces motion blur and ghosting. The result is a clean and sharp image even in hectic scenes. In addition, HDR 10 support expands the dynamic range, improving the contrast between light and dark parts of the scene for a more visually impressive experience.
Ergonomics and Eye Protection
The monitor's stand offers basic ergonomic adjustment in the form of screen tilt from -5° forwards to +15° backwards. This helps you find a suitable viewing angle. The design does not include height adjustment, swivel, or a pivot function for portrait mode. For users who require more advanced positioning, the monitor supports VESA mounting with a 100×100mm pitch. This makes it easy to attach to an adjustable arm or wall. For comfort during long-term use, Flicker-free technology, which reduces backlight flicker, and a hardware blue light filter, which reduces eye strain, are integrated.
Connectivity Options
The monitor is equipped with modern ports for connecting to a computer or games console. To achieve a 200Hz refresh rate at full QHD resolution, you need to use DisplayPort. The HDMI 2.1 ports still support a high 144Hz frequency at the same resolution. This precise connectivity makes it easy to switch between multiple signal sources, such as a work laptop and a games console, without having to constantly swap cables.

Colour Gamut
Determines how accurately a monitor can display colours. sRGB is ideal for web, films or games. DCI-P3/Adobe RGB will be appreciated by graphic designers or professionals at work. The higher the value, the better the monitor displays colours. Maximum Brightness
The value, given in nits or cd/m², determines the brightness level of the monitor. A brightness of over 400 nits is key for HDR content and readability in sunlight, while standard office monitors are fine with values over 250. Refresh Rate and Response Time
The refresh rate (Hz) determines the number of frames displayed per second, so the higher the value, the smoother the image and the less eye strain. A lower response time value (ms) eliminates motion blur. 144Hz+ is ideal for gaming, while values around 75Hz are suitable for office monitors.Specifications
