Custom Resolution Utility (CRU)

[Inputlagger]

I can't add any resolutions on cru. I am trying to force display scaling but when i try to add any ress i cant see on display adapter settings, list all mode.
I want to match my display resolutions and active signal resolutions.
nvidia has the same problem when i set custom res with cvt reduced blank and like others.
When i set this settings my active pixels gone to match my display settings but i cant use causee give me black screen.

My monitor is Alienware AW2521H. Cable is Displayport 1.4.
