Brightness and Contrast
The monitor has 100% brightness and 75% contrast by default. I achieved a 100nit level of white by choosing 44% brightness and 45% contrast. The monitor regulates its brightness by means of backlight modulation at a frequency of 180Hz.
The monitor is over 300 nits bright at the default settings, which is normal for watching movies but too much for work (you want a screen brightness of 70-120 nits for text-based office applications). The contrast ratio is high, almost reaching 800:1.
When I tried to measure the value of dynamic contrast (this feature is enabled with the MagicBright button), the calibrator reported zero brightness for black, so the table contains the calibrator’s accuracy of 0.02 nits. Therefore, the table entry should be read as no less than 15,760:1.
The monitor offers five brightness/contrast presets that can be quickly selected by pressing the MagicBright button. The presets are not editable.
The resulting screen brightness matches the name of the corresponding mode more or less well, but one thing should be noted regarding the Text and Internet modes. The former is only suitable for text-based applications under good ambient lighting. It is going to be too bright for home. The latter suits better for viewing photos or even watching movies rather than for browsing the Web. Well, you can just set the monitor up manually for office applications and switch into a MagicBright mode when you need an increased brightness, i.e. for movies, games and photos.
The MagicBright modes do not affect color reproduction except that each of them has a specific color temperature value: Warm for the Movie mode, Cool for the Sport mode, and Normal for the others.
