If a DVD movie doesn’t fill the screen
• Each side of a double-sided DVD has a different format (standard or widescreen). In widescreen
format, black bands appear at the top and bottom of the screen. To view the standard format, flip
the disk over and play the other side.
If a DVD doesn’t play with two displays
• If both displays are active, press Fn+F5 to switch to one display. You cannot switch displays once
the DVD player is started.
• If you’re using both displays, the DVD image will not appear on any display set up as
“secondary.” Click Start, Control Panel, Appearance and Themes, Display. Click Advanced on
the Settings tab, then click the S3Display tab and change settings.
Display Problems
If the notebook is on, but the screen is blank
• Move the mouse or tap the touch pad. This will wake the display if it is off.
• Try pressing Fn+F2 to increase the display brightness.
• Press Fn+F5 in case the internal display was disabled. (Do this three times to return to the state
you started from.)
• If the notebook is cold, allow it to warm up.
If the screen is difficult to read
• Try setting the display resolution to its default of 1024×768: click Start, Control Panel,
Appearance and Themes, Display, Settings.
• Try adjusting the size of the desktop icons and labels.
If part of the Windows desktop is not visible and you have to scroll down to see the
taskbar, or if the desktop does not fill the entire display and has a black border
• Your display resolution may be set incorrectly. Adjust the resolution as needed.
If an external display does not work
• Check the connections.
• Press Fn+F5 in case the external monitor was disabled. (Do this three times to return to the state
you started from.)
• Test the display with the e-DiagTools diagnostics—see “Using the e-DiagTools Diagnostic Tests”
on page 29.
