Dell Latitude D630 - Manual (Page 57)

Using the Display 57
Switching the Video Image
When you start the computer with an external device (such as an external
monitor or projector) attached and turned on, the image may appear on either
the computer display or the external device.
Press <Fn><F8> to switch the video image between the display only, the
external device only, or the display and the external device simultaneously.
Setting Display Resolution and Refresh Rate
To display a program at a specific resolution, both the graphics card and the
display must support the program, and the necessary video drivers must be
installed.
Before you change any of the default display settings, make a note of the default
settings for future reference.
NOTE: Use only the Dell-installed video drivers, which are designed to offer the
best performance with your Dell-installed operating system.
If you choose a resolution or color palette that is higher than the display
supports, the settings adjust automatically to the closest supported values.
1 Click the Start button and click Control Panel.
2 Under Pick a category, click Appearance and Themes.
3 Under Pick a task..., click the area you want to change, or under or pick a
Control Panel icon, click Display.
4 In the Display Properties window, click the Settings tab.
5 Try different settings for Color quality and Screen resolution.
NOTE: As the resolution increases, icons and text appear smaller on the screen.
If the video resolution setting is higher than that supported by the display, the
computer enters pan mode. In pan mode, the entire screen cannot be displayed
at one time. For example, the taskbar that usually appears at the bottom of the
desktop may no longer be visible. To view the rest of the screen, use the touch
pad or track stick to pan up, down, left, and right.
NOTICE: You can damage an external monitor by using an unsupported refresh
rate. Before adjusting the refresh rate on an external monitor, see the user’s guide
for the monitor.
