alternate brightness change (darkening)
 

Hello,
I've installed BS.Player on my new computer which runs Windows 10 (with all the codecs that come with it during the installation).
For some reason, while watching a movie via the player and without doing anything, the brightness of it changes - one moment it becomes a bit darker, and after about a minute it returns to the original one, and so on and so forth. This transition doesn't seem to be regular (which means that it can probably change after a minute or after half a minute)
It's obviously inconvenient to watch a movie like that, and it didn't occur on my previous computer (which ran Vista).

What should I do?

Thanks in advance!

Is it possible that your videocard automatically adjust monitor brightness depending on image's brightness ?

It is definitely possible since I changed my video card. Where can I cancel the automatic adjustment in the card's control center?

Maybe this could help.

This option of adaptive brightness is already turned off...
Is there another suggestion?
