that the optimal resolution and frequency
setting is 1024x768@ 60Hz.) |

Boot the
computer into VGA
Mode (F8) [repeatedly]
at startup. |
•
|
Go to Control
Panel, double
click Display,
click SETTINGS, and then click ADVANCED. |
•
|
Click Adapter, click List
All Modes and
change the screen resolution to 1024x768.
(You can select 16 bit or 32 bit color
which depends on your video card capability.)

The
“Out of Range” may happen if
you switch monitor A to monitor B for your
PC. Whenever you change the monitor for
your PC, your PC may detect it as a new
hardware and automatically install a proper
driver for the monitor. So, you will have
both monitor A and monitor B drivers on
your PC. Sometimes the two monitor drivers
may conflict each other and cause “Out
of Range”. You can resolve “Out
of Range” by uninstalling both monitor
drivers and reboot your PC. The Windows
XP will automatically detect the new hardware
and install a proper driver for the monitor.
Here is a quick way to uninstall the monitor
drivers: |
| |
1.
|
Right-click My
Computer, select Properties
and then click Hardware.
|
2. |
Click Device
Manager, select Monitor
and click on “+”
in front of “Monitor”.
Then you can see one of the monitor
drivers called “Plug
and Play Monitor”.
A quick way is to uninstall all the
monitor drivers and then let Windows
automatically detect the new hardware.
(Right click on the monitor driver
and select “Uninstall”). |
3. |
Restart your computer. |
