Also, many users conflate the two, but disabling auto-brightness won't solve this behavior if it bothers you. Unfortunately, while you can easily disable adaptive brightness under Settings > System > Display > "Change brightness automatically when lighting changes," there is no easy way to disable adaptive contrast. You should see the screen slowly and smoothly dim and shift in contrast. To simulate the effect, go into a dark room and open Microsoft Word (or anything with a white background) then switch to an app that is all black like Settings (if dark mode is enabled). The effect is most noticeable at night when you tend to have a lower display brightness because you are in a dark room. The feature is standard on modern TVs and high-end gaming monitors, but it can also be a source of frustration. This is also different than High Dynamic Range (HDR), which is much more sophisticated and precise with more color depth. It's like "edge-lit local dimming of specific zones" due to what is on the screen.

Adaptive contrast is quite different than auto-brightness (or adaptive brightness), found under Settings > System > Display, and which ramps up and down the display backlight on ambient lighting conditions.Īdaptive contrast differs because it adjusts based on the current images on your display rather than the ambient light in your room.
