I have two working laptop pcs, and I'm curious about the possibility of combining them into one unit and running both screens as a dual monitor system.

My question is 1) Is this even possible with notebooks, and 2) How do I go about doing this?

I've found a lot of helpful tutorials on the topic in relation to desktop computers... but I'm pretty sure it will be completely different if trying it with laptops. And as I said, I'm not even sure it's possible... but I feel like it should be.

Any tips or links that might help point me in the right direction?

I agree it should be possible, but it's not

Now, in saying that there are ways
One way is to have Remote Desktop setup so one computer can see the other Computer through sharing Remotely
Since one computer can see the full Desktop, you could split the screen to see yours and the other.
But I don't think this is what you want
