Laptop as a monitor for PS4?

Can I use my laptop as a monitor for my PS4?

I think I should go

There's so nh extra app for it on pc called remote play. I recommend that because you don't have kavelvrauchsr but stream the ps4 on the laptop I used to do

No. HDMI ports on laptops are always only outputs.

You can download the "PS4 Remote Play" app. In the app / application itself you can log in with your user data from the PSN and connect the controller via USB cable. If your PS4 and laptop are on the same Wi-Fi, it should work. Otherwise the application gives you suggested solutions.
