hdmi – You can not get 60 Hz in MBPr 13 "2018

I connect my Macbook Pro 13 "2018 with Mojave 10.14.5 to the Fujitsu P27-8 TS UHD external display through the Dell DA301 adapter All the components of this chain are from 4k to 60 Hz. However, I can only get 30 Hz Both HDMI and DisplayPort cables.

I can only get 60 Hz, if under the resolution up to 1280×720!

I tried using cscreen, which did not give me anything, and SwitchResX, which is not easy to use.
Both solutions did not work for me.

Has anyone succeeded in forcing 60 Hz on Macbook Pro 13 "2018 with Mojave?
Thank you!
