Connect the Monitor
To connect your monitor to the laptop, look for the jack that connects the monitor. That jack is mostly used for connections projectors, but there is issue in connecting your monitor there. As you plug in the cable in the jack and turn on your monitor you will be able to see your desktop on monitor. But, you have to make some changes in settings to separate the monitor duplicate display, as you will see the same display on both the screens.
Currently, I am using windows 7 and most of the people have also upgraded to this windows. So, I will tell you about setting external monitor as secondary display while using windows 7
Right click anywhere on your desktop and select “Screen Resolution” (for windows XP users select properties and then go to settings). A window will pop up like given below if you have plugged in secondary monitor.
Now, the first thing you have to recognize is the display. Your laptop screen will be the first and external monitor will be second by default. If you are still unable to recognize just click the identify button to know what number is given to both the displays.
Now, go down to “Multiple displays” and from the options select “Extend these displays option”. In start you might have to face certain problems, when I used it all my desktop icons and start button were shifted to the secondary display. To get these icons back, simply go to Advanced Settings and click on 1 to set it as the main display, as you hit the click you will get all your icons and start button back to your laptop screen.
I think it is quite simple for all of you to track these steps and if you get succeeded, you can enjoy your dual screen system.
