2.Adjust the placement of the monitor and other devices so that they are at least 305 mm (12 inches) apart.

3.Turn on the monitor.

You can reset the refresh rate through your operating system Control Panel.

On the Windows 7 operating system, click Start Control Panel Hardware and Sound Adjust screen resolution Advanced Settings. Then click the Monitor tab and select a new refresh rate.
