" How to Disable a Laptop Monitor to Use a Regular Monitor

by Matt Koble, Demand Media

A monitor connected to a laptop acts as an external, additional display.
Windows enables you to use multiple displays or switch between available monitors. This is useful in situations when your laptop's display is too small for your needs but the information you need is on the laptop. Monitors use different connection types, so make sure your laptop has the same connection type as the monitor and that you have the cable to connect the two. For example, if the monitor uses a VGA connection, your laptop must have a VGA port, and you need a VGA cable to connect the laptop to the monitor.
Step 1
Plug the monitor's power cord into an outlet, and then plug the video cable into the video output port on your laptop and the video input port on the monitor. Turn the monitor on.
Step 2
Right-click the Windows desktop and select "Screen Resolution" from the drop-down list. If both monitors aren't already displayed in the new window, click the "Detect" button.
Step 3
Select "Show Desktop Only on 2" from the Multiple Displays drop-down. By default, the laptop's display is listed as Display 1, so switching to Display 2 puts the picture on the second monitor, while the laptop monitor remains blank."
