Well, putting it simply: I've got a laptop (NEC Versa) and my parents have a pc with a monitor, but the pc is currently not in working order, so the monitor is free to use. Now that seems like a wonderful opportunity to plug it into my computer and temporarily increase the size and quality of my working screen. Only, my laptop won't let me set the primary monitor to the pc monitor - all I can do is extend my desktop onto it.
I used to do it all the time, until an annoying virus hit my laptop and I ran a complete system reinstall. I had to download all chipsets and codecs and drivers and whatnot again after that, an since this is the first time that I've tried to use the multiple monitors feature since then, perhaps I've missed a driver or whatnot? Google didn't prove quite so helpful this time, so I don't know... Any ideas? Anyone?
Thanks in advance

Go into device manager.

Go to start.
Click on run.
Type in devmgmt.msc

Do you see any ? ! or X.

Only under Other Devices. The "biometric coprocessor" has an !, but I always assumed that to be for the fingerprint recognition feature.

For display adapters does it show the correct drivers?

When you go into display properties under settings does it show a picture of 2 screens?

[Maelspike]

Yup, display adaptors shows correct drivers... And settings shows two screens - only the "primary" option when I right-click on screen 2 is greyed out.

Screen 2 on my portable computer does not have a option of primary display.

Check with NEC for any drivers you may have missed. I've worked on a Sony laptop with a similar issue, and it turned out you had to use the Right-click menu on the desktop to change the screen output--It was something to do with the Intel graphics adapter if I remember right.
