If the slight changes to brightness while you are Web browsing or viewing any other dynamic content on the screen bother you, then you should look in your graphics driver settings for a feature that is described as 'power saving' and disable it. We have found this behaviour to be tied to power management settings in graphics drivers, which, when disabled, allow the screen to maintain a constant brightness level. Thanks to its easy portability and high-quality panel, the M14 is a good choice for businesspeople or consumers who have a laptop with a USB Type-C port that. The subtle changes that occur when going from a dark background on the screen to a light coloured background have nothing to do with the 'Adaptive brightness' setting, but instead are a result of graphics driver settings.
In that scenario, the brightness changes based on the room lighting. That setting works using the ambient display sensor on a laptop. This behaviour is a dynamic brightness change that is unrelated to the 'Adaptive brightness' setting in Windows.
These changes happen automatically after a couple of seconds, and they can also sometimes manifest as noticeable flickering.
On a dark background, the screen will dim automatically, while on a bright background it will brighten.
On some laptops, you may have noticed a change in brightness as you go from a screen with a dark background to a screen with a bright background.
