Maybe it sounds strange but after updating to kernel 4.4.4 I encountered with some problem: my screen became too dark and looks like "high contrast". I can't say surely that it is not my PC problem but everything works normal on 4.4.3.

Searching with git bisect reports that first bad commit is:
[6de4682d2845d6aa8883ae62e3ed1b2f915df4e8] drm/i915/dp: fall back to 18 bpp when sink capability is unknown

Hardware details. 
Monitor: LG "23MP67D" connected to Display port. 
Processor: Intel(R) Core(TM) i5-6600
