Changing the Default Video Display Driver
After configuring the video display and restarting the system, you may need to configure the
system to use the installed video display driver by default.
To change the default video display driver:
1.
From the operating system Start menu, go to Settings/Control Panel/System.
2.
Under Operating System, select the Startup list; then select the appropriate non-VGA option
from the displayed list, and click OK.
Correcting Initial Video Display Problems
If the system’s video display is black, not synchronized, or distorted after you restart the system,
you may have a video configuration problem. Do not press
CTRL
+
ALT
+
DEL
to log on. Instead, try
to correct the problem by using the Last Known Good option to return the system to the last known
good configuration recorded by the operating system.
To use the Last Known Good option:
1.
Power down and restart the system.
2.
Press the space bar when prompted to display the Last Known Good menu.
If using the Last Known Good option fails to correct the video display problems, you can obtain a
functional video resolution by restarting the system in VGA mode.
To restart the system in VGA mode:
1.
Power down and restart the system.
2.
At the boot screen, select the VGA mode option.
After logging on in VGA mode, check for the following common problems and solutions:
♦
A multi-sync monitor is selected, but a graphics display device with different video timings is
connected to the system. Select a different monitor type.
♦
The monitor selection is incorrect. Select a different monitor type.
♦
There is not enough video display memory to support the selected resolution and color depth.
Install and reconfigure the video display to use a lower resolution and color depth.
Restart the system and, when the boot screen displays, select the appropriate non-VGA version of
the operating system to use the reconfigured video display driver. If problems persist, contact the
Customer Response Center for help.
