Select “1280 by 1024, High Color (16 bit), Default Refresh” Click on“OK”and“APPLY”.
Afte r clicking “APPLY” button, a message will be displayed “our 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
After you restart, go back to “List All Modes”to adjust your screen refresh rate to 60 Hertz.
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 ca n resolve “ut 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 “Monito r” 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”). Restart your PC .
