to get 144hz, you need to use DVI or Displayport cables. Also you need to go into your monitor settings under windows control panel and select advanced settings. From there you will change the default 60hz to 144hz, you will see 75hz, 100hz and 120hz available as well.

here is a snipit from the net:
-----
Search for Display Settings in Cortana/Search bar
On the left side click Display then near the bottom click Advanced Display Settings
It will take you to the page where you can change your resolution. At the bottom of the page select Display adapter properties
A new window will appear.
On one of the tabs at the top select monitor.

Hope this helps!
