I only get 60hz on 144hz monitor

[finckenm2003]

Hi, I have recently bought a 144hz monitor and have plugged it into my laptop with hdmi. In the screen settings I am only allowed to set it to 60hz and no more. I know displayport is recommended but my pc doesnt have an inlet for anything else than hdmi. The cable I am using is called "high speed hdmi cable with ethernet".
My PC has a 960m GPU. Is it possible for me to display in 120 hz or more? thank you
