I wanted to get a 144hz monitor to connect my Ps4 and my laptop. Now I have a question: I have read that if you connect the HDMI cable to the laptop, you only get a maximum of 60hz, but with the display port you get the full power of 144hz to the laptop. Is that true or can I also get 144hz on the laptop with the Hdmi cable (it can play over 144fps etc)?
Normally you can also reach 144Hz with an HDMI cable, but I would still recommend a Displayport cable.
Brings you even better quality and certainly also the 144Hz!
With an HDMI port you also get 144hz from the 2Gen, but you have to check which connection your laptop has. Otherwise DP is the better solution
What is in the case of 2Gen?
Do you have to look online should be in the description of your laptop. https://www.burosch.de/netzwerke/400-hdmi.html
