Refresh Rate - Stuck at 120Hz - Samsung 57" LED - LS57CG952 - M4 Max

Is there a way to get the full 144hz out of this monitor instead of just the 120hz? I'm connected to it via HDMI 2.1, but the most I can get is 120 hertz.

144hz can be achieved with Display Port 2.1 cable.

So, HDMI 2.1 can, but not with MBP? I just ordered a DP 2.1, hopefully you're right! Thank you!

Well, I purchased that new cable and still at 120Hz... This is the cable I purchased - https://a.co/d/0Br78DA - now what?
