Hello... You can only plug HDMI outputs to inputs... and outputs to inputs.
You could network the Comps together thou ( wifi/cable) and send screens shots and clone Displays between them.

No sorry. they only have video out not in.

Not through the HDMI out port on the laptop..

Most likely no. You'd need a laptop with a video input and those are rare (if they exist at all).

You could make it show the exact same thing as your main screen with VNC but that isn't really what you want.. You might be able to hook it up to your TV and use the TV as a second screen..

This used to be easy under Windows 7 and an Intel CPU which supported QuickSync. You could use QuickSync on the first laptop to create a new virtual monitor, then have the second laptop display that virtual monitor using something like VNC. Unfortunately creating the virtual monitor doesn't seem to work anymore with Windows 8.

Depending on exactly what it is you're trying to display on the second laptop, there are a variety of tools which might do the trick. Many of them also support using a tablet as your second device. These are suitable for simple displays like web browsing (speed is determined by your network). They will probably be unsatisfactory for video or games.
