So here is my situation. I'm going to build a desktop computer at the end of the month. I currently have a laptop connected to a desktop monitor, I really need two monitors to be productive. But when I get the desktop it won't have an internal monitor or anything.
So what I want to do is be able to connect my desktop to my desktop monitor using a DVI port, and then connect another monitor to my desktop using the VGA port on my laptop. Or in other words use the laptop as a secondary monitor for my desktop.
I'm wondering if there is any way to do this. I'm just wanting to turn the VGA output into a VGA input on my laptop.

It is not possible. The output on laptops are output only. Unless you use software over a network. However there is no hardware way.
EDIT: This is the only hardware thing I can find.
I did find a forum where someone talked about a PCMICA card that you could put in your laptop, someone said that the resolution would be really low. Here is the link to the forum though: http://www.daniweb.com/forums/thread723.html
make no guarantee that this will work. I don't think it will work. I am just providing this after a quick Google Search*

It should be possible with the proper cable but Iâ€™m not acquainted with the specifics so I apologize that I canâ€™t give a detailed answer.
Itâ€™s possible youâ€™ll likely take a hit in the resolution if the laptop has a maximum resolution thatâ€™s lower than a desktop.
