#144hzlaptop

I got a new laptop a bit ago and it said it was 144hz but it's not. I cant go to display on the NVIDIA control panel because it's not there. When I right link and go to display setting it only shows 40hz or 60hz. My laptop is a ASUS TUF GAMIMG A15 with a RTX 2060 and a Rysen 7 4000 with "144z"...
