Black colour abberation

Hello,

I have a problem with black colour in movies. Deep black is shown as blue, which looks terrible.
I found info here: video_levels_and_color_space (wiki)
and it seems that I have blacker-than-black issue. The problem is, that I do not know how to correct it.
I use KODI on Asustor AS-3002 NAS +TV connected via HDIM.
What am I to change to receive normal black colour?
