I need help. I was trying to set up dual monitor on our church computer and messed it up. The computer monitor is now identified as monitor 2 and the video screen is identified as Monitor 1. The desktop of the pc now shows on the video screen. I know there is a keyboard shortcut, at least there was on a laptop I used several years ago. This is a desktop computer by emachines that I use at church.

Can you please provide us also the barnd and model of your video card because its important so we can provide you the correct settings....You can also try this connect this monitor to the DVI port on your video card output then restart the computer and if you have teh setup CD for this monitor just run it and let it configure the settings for you...
Check and see if your NVIDIA drivers are up to date. Then try changing the resolution on your laptop to match the native resolution on the monitor and see if it works. If it does then you will need to look for the option to set custom resolutions on each monitor so that you can have both devices working at diferent resolutions if 1 is wide screen and the other is not.
Let me know if this does not work and you need more help.
On the Settings tab, click Identify to display a large number
on each of your monitors, showing which monitor corresponds with each icon.
Click the monitor icons and drag them to positions that represent how
you want to move items from one monitor to another, and then click OK or
Apply to view changes.
To open Display, click Start, click Control Panel, and
then double-click Display.
The icon positions determine how you move items from one monitor to another. For
example, if you are using two monitors and you want to move items from one monitor to the other by
dragging left and right, place the icons side by side. To move items between
monitors by dragging up and down, place the icons one above the other. The icon
positions do not have to correspond to the physical positions of the monitors.
You can place the icons one above the other even though your monitors are side
