I use the keyboard keys; same thing.
, newer/smart tv's also have this, and perhaps even newer monitors. There are 2 things, 1 adaptive brightness which can be disable in the edit power plan in Windows. And the 2nd one is adaptive contrast, which iirc can only be disabled through the registry. With tv's you will have to delve into the settings/advanced settings and disable dynamic/adaptive contrast/brightness things and set dynamic contrast to zero etc (the terms can differ a bit per smart tv / tv).
