Reference Guide 101
If the OmniBook is cold, allow it to warm up.
If the screen is difficult to read
Check whether the display resolution is set to its default setting, 1024 × 768 (XGA).
Check this in Start, Settings, Control Panel, Display, Settings.
Check brightness (press Fn+F2 to increase brightness).
If an external monitor doesn’t 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.)
The external monitor may not be detected. In the BIOS Setup utility, try setting Video
Display Device to Both in the Main menu. See “To run the BIOS Setup utility” on
page 86.
If the monitor is connected to a video adapter in a docking system, in BIOS Setup
make sure the Primary Video Adapter is set to Auto in the Main menu.
If the image on an external monitor or projector is unstable
Press Fn+F5 to turn off the built-in display. (Do this three times to return to the state
you started from.)
Change the display properties of the OmniBook display to match the resolution of the
monitor or projector. In Control Panel, open Display, Settings and change the
Desktop Area or Screen Area setting.
Use a monitor or projector that matches the resolution of the OmniBook display.
If multiple display support doesn’t work in Windows 98
In Windows 98, the computer supports multiple independent displays using the built-in
display and an external monitor connected to the monitor port. You can also add an
independent display using a video adapter in a docking system.
Check the monitor connections.
If the monitor is connected to the OmniBook monitor port, you might have to reduce
the resolution and number of colors for the built-in display to make more memory
available for the external monitor. See “To use an external monitor” on page 69.
If the monitor is connected to a video adapter in a docking system, in BIOS Setup
make sure the Primary Video Adapter is set to Internal in the Main menu. See “To run
the BIOS Setup utility” on page 86.
