I am new to using Raspberry Pi (mine is version 2 Model B) and am setting it all up. I have an HDMI enabled laptop and don't need the internet to do what I need to with the Pi. Is that sufficient? I keep seeing info about connecting to laptop with network cables, but I am assuming that is only if you need to go on the web. Currently downloading Noobs, Win32DiskImager, and SD Formatter, so thought I would ask this while I wait. Thanks!
Laptop HDMI ports are generally output only, meaning it can only be used to display the laptop's screen on another device. Your HDMI port needs to be HDMI input enabled, which is unusual for these kinds of computers. If you had an external display for a desktop, those are solely input only and will work. Then again... Thats what the RPi needs anyways.
This is also why playing a game console like an XBOX or Play Station won't work. The "signal" only goes one way (output) on a laptop's HDMI port.
I want to add that all the tutorials "with network cables" are not neccessarily only talking about internet connections.
They enable you to use the Raspberry without a directly attached display.
This works by using a "Remote desktop" (VNC , RDP) software which communicates over the single Ethernet cable inbetween the Pi and Laptop after setting up "Internet Connection Sharing" .
