Lenovo 3000 and a secondary monitor

[delazar]

I have a Lenovo 3000 V100 Laptop. I want to use a secondary monitor/display. I see the display on both the primary and secondary monitors until windows finishes booting and then the secondary monitor goes blank. I try FN F7 to no avail. I am using windows XP. I assume this is a setup problem.
Please advise.

Use the Intel Graphics utility.

Should be: Control Panel>Display> Settings> Advanced

Look for the Intel tab.

Go into BIOS before the machine fully boots up & check that BIOS is set to automatically detect an external monitor - you probably already have this in action, but check to be sure.   Duck3's suggestion is the next key part.

Thanks - this really helped. The <FN> <F7> does not work to switch monitors and/or have them both active. Any suggestions?

Not having your exact model, try this.  

Go to your desktop display.  

Position your pointer over part of the display without any icons, open windows, or tasks.

Right click.  

A menu should appear, click on "Properties" or "Graphics Properties" whichever is on the menu.  This should open another menu, one tab on which can be selected to allow you to display the same thing on the internal and an external monitor.   The graphics adapter software on my Lenovo displays its menu this way.   I'm not sure if going through the Control Panel selection will get you to the same point.
