Hi@nareznoj,
Welcome to the HP Support Community!
It is a bit confusing. Please follow the physical connections,
let's Verify the correct input: Monitors with multiple input options need you to manually select which cable or HDMI port you're using, like HDMI 1, HDMI 2, DisplayPort, Please let me know the secondary monitor connected to which port on the notebook.
Hope this helps! Keep me posted.
