Using Dual View
Dual View enables users to expand their computer screen over two display devices.
Dual View is convenient when a wide operating space is needed. In addition, since Dual
View operates as if there are  graphic cards present even when there is only one, you
can set the resolution and color for each display device.
Selecting Dual View
Check if the external display device
is properly connected and follow the
instructions below.
1
Click the Start > Control Panel >
Appearance and Personalization >
Adjust screen resolution.

Click on the number  monitor icon
and select Extend the desktop onto
this monitor. Click Apply and then
click the OK button.

When notebook LCD is set as the
main device, the 1 digit is displayed
over it and the  digit is displayed over
the auxiliary display device. Now you
can expand the Desktop screen over
2 display devices.
When using Dual View, it is
recommended setting the LCD as the
main device (number 1).
If the screen of the auxiliary display
device is displayed, click the Start >
Control Panel > Appearance and
Personalization > Adjust screen
resolution > Monitor Number 2 and
adjust the resolution and color quality.
