benq xl2411p and GeForce GT 1030

[weirdo]

Hello

i bought used benq xl2411p and now i cant reach 120 hz on hdmi or dvi with my Gigabyte GeForce GT 1030 OC 2GB GDDR5 (GV-N1030OC-2GI).

These is picture from producent side:

so, i should reach 120 hz?

I`m trying some custom resolution like this: https://imgur.com/a/h8nwn but test pass correct but i cant save it. But i can save for example 1440 x 900 with 100 hz.

So, i download cru and now i achieve 90 hz on 1920 x 1080, but not more because i have to restore drivers. When i`m trying nvlddmkm-patcher-1.4.8 with my nvidia driver 446.14 Standard benq monitor is black and on my second monitor i have 1920 x 1080 with 1 hz (but it seems like 60 hz).

It`s some screen from cru:
   

What can i do? New graphic card? Restore nvidia drivers to some old version and try
nvlddmkm-patcher?


// I installed nvidia driver 442.50 and i used nvlddmkm-patcher-1.4.8 and for while i achieve 95 hz with hdmi cable on 1920 x 1080 but i cant reproduce that.
