24" Dahua LM24-B221S
The Dahua 24" LM24-B221S monitor is a display device for both work and play. This 24" Dahua monitor combines a fast refresh rate with the faithful colour reproduction of IPS technology. Its Full HD resolution of 1920 × 1080 pixels shows sharp details, which you'll appreciate when working with documents and watching multimedia. For gamers, the key feature is the 144Hz refresh rate, which, along with the 1ms (MPRT) response time, delivers a smooth image without tearing or blurring in fast-paced scenes. The panel offers true-to-life colours and wide viewing angles, typical of IPS technology. The matte screen surface effectively suppresses unwanted glare from ambient lighting, and Low Blue Light technology reduces eye strain during prolonged viewing. As an office monitor, the Dahua offers reliability and a clear picture, while as a 24" gaming monitor, it provides the necessary performance.

Detailed Image with IPS Technology
The image is based on a 24" IPS panel with a Full HD resolution of 1920 × 1080 pixels and a 16:9 aspect ratio. This technology offers wide viewing angles of 178° horizontally and vertically. This means the image retains its colour accuracy even when viewed from the side. The panel covers 72% of the NTSC colour space and offers a 1,200:1 contrast ratio, contributing to vivid colour reproduction and deeper blacks. The brightness reaches 250cd/m², which is sufficient for normal office and home environments. In addition, the panel's matte finish reduces glare and light reflections.
Monitor's Gaming Performance
The monitor optimises smooth gaming thanks to its 144Hz refresh rate. This rate redraws the image 144 times per second, resulting in significantly smoother motion and less lag compared to standard 60Hz monitors. The smoothness of the image is complemented by a fast 1ms (MPRT) response time, which effectively eliminates ghosting and motion blur. This combination of parameters is key for competitive gaming in action, racing or FPS titles, where every millisecond counts. Connection via DisplayPort 1.4 or HDMI 2.0 supports the full refresh rate at native resolution.
Comfort for Work and Play.
The monitor also considers user comfort during long-term use. It integrates Low Blue Light technology, which reduces blue light emissions through software. This reduces eye strain during prolonged use, especially in the evening. The ergonomics are supported by a tilting stand, which allows the screen tilt to be adjusted from -5° to +15°. For more advanced positioning or to save desk space, the 75 × 75mm VESA mount can be used to attach the monitor to a compatible stand or arm.
Connectivity Options.

Colour Coverage (Gamut)
Determines how accurately a monitor can display colours. sRGB is ideal for the web, films 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
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 values above 250 are sufficient for standard office monitors. 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) eliminates motion blur. 144Hz+ is ideal for gaming, while values around 75Hz are suitable for office monitors.Specifications
