screen resolution to 1280x1024. (You can select 16 bit or 32 bit color
which depends on your video card capability.)

Click on the “OK” and “APPLY”.
After clicking the APPLY button, a message will be displayed “Your
desktop has been reconfigured. Do you want to keep these settings?”
Click “Yes” and “OK”. Then click “OK” on the Display Properties
window.
Restart your PC

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 will automatically
detect the new hardware and install a proper driver for the monitor. Here is
a quick way to uninstall the monitor drivers:
Right click on “My Computer”, select “Properties” and click on
“Hardware”. Click on “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”).
