Correcting 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. You may be able to correct the problem
by restarting the system in VGA mode. On a system running Windows NT, you may also be
able to correct the problem by using the Last Known Good option to return the system to the
last known good configuration recorded by Windows NT.
To use the Windows NT Last Known Good option:
1. Power down and restart the system.
2. When prompted to display the Last Known Good menu, press the space bar.
3. 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 appropriate for your system.
Check for the following common configuration problems and solutions.
u
A multi-sync monitor is connected to the system, but a multi-sync monitor type is not
selected, and the display driver cannot determine this by querying the monitor. Select an
appropriate multi-sync monitor type.
u
A selected resolution, depth, or refresh rate is not supported by the multi-sync monitor.
Try using different video display settings.
u
The Dual Screen option is selected, but only one video display adapter is detected. Clear
the Dual Screen option.
u
A multi-sync monitor is selected, but a monitor with different video timings (such as an
Intergraph InterVue monitor) is connected to the system. Select the appropriate monitor
type.
u
The monitor selection is inappropriate for the multi-sync monitor attached to the system.
Restart the system in VGA mode, and then select a new monitor.
u
A graphics resolution and color depth has been selected that exceeds installed display
memory. Restart the system in VGA mode, then open Display in the Control Panel to re-
install and configure the display driver as described in the video display adapter
documentation delivered with the system.
Restart the system and select the non-VGA version of the appropriate operating system to use
the reconfigured video display driver.
