I will say though, I used a cheaper HDMI cable that I recently got on Amazon, and while I was getting 165hz, I started experiencing 'drop outs' while using that cable

So yes, your HDMI cable is going to need to be halfway decent, but buying an expensive 'highspeed' HDMI cable is not going to magically get you high refresh rates if you laptop can't push those refresh rates to begin with

And if u are confuse about the port, if u don’t have display port which I don’t have on my laptop, HDMI 2.0 also give u a full 165hz if u are still confuse.
