27" Dahua LM27-B221S
27" Dahua LM27-B221S
The Dahua 27" LM27-B221S monitor is a versatile display device with a 27" screen size and a 1920 × 1080 pixel Full HD resolution. This Full HD monitor uses IPS panel technology, which provides wide viewing angles of 178° horizontally and vertically, and consistent colour reproduction. It has a 144Hz refresh rate for smooth display of fast-moving scenes. Gaming and multimedia content benefit from the low 1ms (MPRT) response time, which reduces motion blur. The matte screen surface with 25% haze and 3H hardness effectively reduces glare from ambient light sources. This 144Hz Dahua monitor also includes software-based blue light protection to help reduce eye strain during prolonged use.

Detailed picture and smooth motion
The 27" IPS panel with a Full HD resolution of 1920 × 1080 pixels displays content in a 16:9 aspect ratio. The high 144Hz refresh rate combined with a 1ms (MPRT) response time reduces motion blur and ghosting, which you'll notice when playing games or watching dynamic videos. The panel achieves a brightness of 250cd/m² and a native contrast ratio of 1,200:1. Colour reproduction covers 72% of the NTSC space. The picture is fine enough for general office work and home entertainment.
Ergonomics and mounting
The monitor stand allows for basic ergonomic adjustment by tilting the screen from -5° to +15°. For more advanced positioning or to save desk space, the monitor offers preparation for VESA mounting with a size of 75×75mm. This allows it to be mounted on a wall or a compatible arm. The thin bezel design on three sides makes it easy to set up multiple monitors side by side. The dimensions without the stand are 36.3 × 61.41 × 4.51cm and the weight of the panel itself is 3.84kg.
Integrated features and eye protection
The monitor includes two integrated 2×1W speakers that provide basic sound for system notifications or casual listening without the need to connect external devices. An important feature is the software technology to reduce blue light, which reduces eye strain during long periods of work or gaming. The matte finish of the screen also contributes to visual comfort, reducing distracting glare and reflections from ambient lighting.
Connectivity and operation
SDR mode consumption is 21W, which places the monitor in energy class E. Power consumption does not exceed 29W and drops below 0.5W in standby mode. The package includes a power adapter and an HDMI cable for immediate use. The monitor offers a wide range of options for connecting to various devices. Digital video inputs and an audio output are available.

Colour coverage (gamut)
Determines how accurately the monitor can display colours. sRGB is ideal for web, movies or games. DCI-P3/Adobe RGB is appreciated by graphic designers or professionals at work. The higher the value given, the better the monitor displays colours. Maximum brightness
Given in nits or cd/m², this value determines the brightness of the monitor. A brightness of over 400 nits is crucial for HDR content and readability in sunlight, while standard office monitors only need values above 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 picture and the less eye strain. A lower response time (ms) value eliminates motion blur. 144Hz+ is ideal for gaming, while values around 75Hz are suitable for office monitors.Specifications
