mode, however, the actual resolution setting will display. Both the Simulscan and Display
Fn/function key commands will work in this situation. This allows you to set up the following
arrangement:
1. In the system Setup program on Page1, Standard Setup, make sure the Boot Display line
is set to “Auto-detect”. This is the default setting so it should already be set for this unless
you changed it.
2. Reboot and set the Windows driver to the high resolution and 16- or 256-color mode you
want using the Video Changer utility.
• When you use the computer with no external monitor connected, the auto-detection
feature will set the video display to run in LCD-only mode at a resolution of 640 x 480.
• When you connect an external monitor, the system will operate in CRT-only mode and
the monitor will display the higher resolution.
Display Driver Limitations
There are two limitations to how you can use the video display drivers. The first is that you can
not use the high-resolution drivers in Simulscan mode. You have to use the method described
above to switch between standard resolution o the LCD panel and higher resolutions.
The second limitation concerns the HiColor modes. The HiColor modes will only work on an
external monitor and when you use them the display switching Fn/Function key commands F6
and F10 do not work. Moreover, if you try to run Windows using a HiColor mode in Simulscan
or LCD mode, Windows will not run and will produce an error message saying that the driver
does not support that configuration. If you have this problem, shut down, connect an external
monitor, run Windows again and use the Video Changer utility to switch to 16- or 256-color
mode. You can then return to LCD-only operation.
