So i am moving out of my parent's place to go to university.. the problem is, my PC was using the room's TV as monitor. And I can't take that. I have a laptop, but that doesn't have a display input.. can i use the ethernet cable instead?
If you are trying to send video over Ethernet from your desktop PC to a laptop display, is not possible.
If both, laptop and desktop will be in the same network, you could use a program to access and view the content of your desktop from your laptop (uvnc).
