Thanks for your answer.
It's possible I have found the nature of the issue but I have to test it.
I have seen in the forum it is probably due to the connectic.
Indeed, the HDMI cable seems to not allow a higher refresh rate than 60 HZ but with a dysplay port it could work.
I am waiting for this cable to do test and check it.
