27" Dahua LM27-A221Y
27" Dahua LM27-A221Y
The Dahua LM27-A221Y monitor delivers a Full HD resolution of 1920×1080 pixels on its 27" screen. With its 27" screen size and 144Hz refresh rate, this monitor provides users with a smooth picture without compromising on colour reproduction. At the same time, with its Full HD resolution, IPS panel with true-to-life colours and wide 178° viewing angles, the monitor will satisfy even for normal work or watching films. The fast 1ms MPRT response time reduces motion blur, which is important for a clear picture in dynamic scenes. The screen is framed by a narrow bezel, which promotes a modern look and makes it easy to use multiple monitors side-by-side. The Dahua LM27-A221Y is therefore a versatile display device for everyday use.

Image Properties
The image is based on a 27" IPS panel with a Full HD resolution of 1920×1,080 and a 16:9 aspect ratio. This technology ensures consistent colours from viewing angles of 178° horizontally and vertically. The screen has a brightness of 250cd/m² and a contrast ratio of 1,200:1. The gaming experience is enhanced by a high 144Hz refresh rate and a 1ms (MPRT) response time, or 5ms (GtG) respectively. The refresh rate has been overclocked from a native 120Hz. The colour rendering works with an 8-bit depth and covers 72% of the NTSC space.
Ergonomics and Mounting
The monitor stand allows basic screen positioning to adapt to your workspace. The panel allows tilting from -5° forwards to 20° backwards to find the optimal viewing angle when seated. For greater flexibility and to free up desk space, the monitor supports VESA 100×100mm mounting. This compatibility opens up the possibility of mounting it on a wall or on an adjustable arm, which you will appreciate when creating multi-monitor setups or when you require specific height and screen distance settings.
Operating Features and Eye Protection
The monitor integrates Flicker-free technology, which reduces invisible backlight flicker, reducing eye fatigue during long work or gaming sessions. The device belongs to energy class D in SDR mode, where its typical power consumption is 27.1W. Without the stand, the monitor measures 36.41×61.51×4.91cm and weighs 3.4kg. The ultra-narrow bezel design on three sides facilitates seamless transitions in multi-monitor setups.
Connectivity Options
Both digital and analogue inputs are used to connect to a computer or other signal sources. The modern HDMI 1.4 interface is essential to exploit the full potential of the monitor, as it transmits a Full HD image at a refresh rate of 144Hz. To ensure wide compatibility, the monitor also includes an analogue VGA port, which is used to connect older computers or laptops. The presence of both ports simplifies integration into a variety of work environments without the need to purchase additional adapters. A practical addition is the included HDMI cable.

Colour Coverage (Gamut)
Determines how accurately the monitor can display colours. sRGB is ideal for web, films or games. DCI-P3/Adobe RGB is appreciated by graphic designers or professionals at work. The higher the stated value, the better the monitor displays colours.Maximum Brightness
The value, given in nits or cd/m², determines the brightness of the monitor. A brightness above 400 nits is key for HDR content and readability in sunlight, while standard office monitors are sufficient with values above 250.Refresh Rate and Response Time
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
