benq xl2411z I cant set 120hz

[Comb]

Hello there, I moved from my old system to a new one. Fresh windows install. New videocard without dvi-d. I tried to use an active adapter dvi-displayport and was unable to set higher than 60hz, I bought a cable dvi-displayport (passive adapter basically) and it didnt work either.
But I think that i messed up something because at some point when i just installed win10 i was able to get 70hz ^_^ not more but still... now i cant get past 60hz.
Maybe I did not tweak some basic settings.. my firmware is v2.

I used XL2411Z WHQL Driver for Win10 from here https://www.benq.com/en-us/support/down ... river.html
tried to auto update the driver with win10 it made it to zowie series lcd did not work either.

I did not install Display Pilot.
I tried to disable my second monitor.
BlurBustersStrobeUtility detects the monitor and works if I enable blur reduction, not a great idea without 120hz tho...
DDC/CI is ON
I was unable to find some basic guide to check all the stuff I need, but after typing this post I have a feeling that I am an idiot because I did not try display pilot software

Make sure you are using a Dual Link DVI-D cable and not a Single Link one.
