HDMI port only works @30hz with any resolution

Product Name: HP Pavilion - 15-au116nl
Operating System: Microsoft Windows 10 (64-bit)

Hi All,

Firstly a would apologize for my poor English.

I have a HP Pavilion - 15-au116nl  with this graphic cards:

intel HD620 and InVidia 940mx. (HDMI port is on intel device)

When I connect an external display it works only with 23-24 hz frequency selected by the intel graphic panel with any resolution.

I have non possibility to choose resolution or frequency from invidia device panel.

It is not a problem of cable or monitor because I try with my surface pro 3 with mini-display port with the same cable and monitor and it works at 1920x1080 @60hz.

I would like to know if it's a problem of my HP notebook?

Help me
