BenQ XL2430T. The display problem dark.

Good afternoon. Who understands the problems of the Benq please help.

Monitor take long time, but decided to ask just now. The problem is
the following:
the monitor is set to my taste. Installed Black eQualizer 15. in the transition from
the light phase to the dark this feature Black eQualizer (BeQ) works as expected. But if
there is a dark scene (e.g. just a black screen or in games when there is no
lighting, or conventional dark room) and it goes to light then this
transition and not. ie, everything stays very, very dark. Have on the panel (at
I prepared the config) to press digit 1 in order to be activated BeQ 15 and the scene
dark became light again with the same BeQ installed on 15. Question: can
to get rid of the need to press on the remote control unity to dark
the stage became bright?
Added a video example of the game NiOH. The entrance to the premises used settings 1 - after login - the picture is darker than default settings. After the dimness of the screen I hit the restart button 1 with my settings and the game again became bright.
