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, 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. 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.* All images on this page are for illustrative purposes only.
