27" Dahua LM27-B221
The Dahua 27" LM27-B221 monitor combines a large 27" screen with a Full HD resolution of 1920×1080 pixels. It is suitable as a gaming monitor and as a spacious office monitor. The IPS panel displays consistent colours across wide 178° viewing angles. A high refresh rate of 144Hz and a response time of 1ms (MPRT) ensure smooth motion without blurring, which you'll notice in fast scenes in games or videos. The matte screen surface effectively reduces unwanted glare and improves readability in brighter lighting. You can connect it to your computer or console using modern DisplayPort 1.4 and HDMI 2.0 ports.

Display Quality and IPS Technology
The display uses IPS technology, which offers wide viewing angles of 178° horizontally and vertically. This keeps colours consistent even when viewed from the side. The 1920×1080 Full HD resolution with a 16:9 aspect ratio displays sharp details. The colour spectrum covers 72% of the NTSC standard and the native contrast ratio is 1,200:1. A brightness of 250 cd/m² combined with the matte finish of the panel, which absorbs ambient light, effectively prevents distracting glare.
Smoothness for Games
For gamers and fans of dynamic content, a high refresh rate of 144Hz is key. The monitor redraws the image 144× per second, ensuring significantly smoother motion than standard 60Hz monitors, especially in fast action or racing titles. The 1ms (MPRT) response time also contributes to a sharp display of fast scenes, limiting motion blur and ghosting effects. This combination of parameters provides a noticeable advantage in competitive games where precise and fast reactions are crucial.
Ergonomics and Mounting
Included in the package is a basic stand that allows the screen to be tilted from -5° to +15° to set the optimal viewing angle. For greater flexibility, the monitor offers 75×75mm VESA mounting holes on the back. This solution allows the monitor to be attached to an adjustable arm or directly to the wall, freeing up space on your desk. The dimensions of the panel itself without the stand are 36.3×61.41×4.51cm. The thin bezels on three sides also make it easy to set up multiple monitors side-by-side.
Connectivity Options
You can connect the monitor to modern graphics cards, laptops and gaming consoles using the digital inputs. Versatility is confirmed by the presence of a DisplayPort 1.4 port and an HDMI 2.0 interface, both of which support full Full HD resolution at a high refresh rate of 144Hz. This allows you to use the monitor's power without compromise. A 3.5mm audio output is also included for easy connection of headphones or external speakers.

Colour 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, 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 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 picture and the less eye strain. A lower response time (ms) eliminates motion blur. 144Hz+ is ideal for gaming, while values around 75Hz are suitable for office monitors.Specifications
