"Virtual" monitor emulator

Hello, i was wondering if anyone knew a way to get some sort of VNC server or some other program in order to get to display a HDMI in signal.
As i wanted to connect something like a Raspberry pi HDMI to my laptop's video card,  and display the output of the HDMI into some sort of screen emulator (my laptop has also Thunderbolt 3, if thats usefull).
I would need that setup as i'm soon going to college and i won't have access to a monitor, but still i will need to do my tinkering with my raspberry pi.

Thank you all.

If you require the HDMI output, then you'll need an hdmi capture device.
For example: https://www.reddit.com/r/linux/comments … i_capture/

Otherwise you could set up a VNC server on the RPi (using SSH) and then connect to that through ethernet with a vnc client.

Yes, the issue is that im going to a college where there is no ethernet connection, so i would have to setup wi-fi on the pi, but how do i do that if i don't have a monitor?
Also, i won't be using a window manager on the RPI but just tty, so ssh is enough.

You do not need your college to provide an ethernet connection. Your laptop just needs to have an ethernet port or you can use a usb-ethernet dongle.

You can enable ssh without a GUI: 3. Enable SSH on a headless Raspberry Pi (add file to SD card on another machine)

On Arch Linux you might have to start a dhcp server
