Notes

• To open Display, click Start, click Control Panel, and then double-click Display.
• The default refresh frequency setting is 100 Hertz, although your monitor may support a higher setting. Check your manufacturer's documentation for information regarding the settings your monitor supports.
• A higher refresh frequency reduces any flicker on your screen, but choosing a setting that is too high for your monitor can make your display unusable and cause damage to your hardware.
• Changes to the refresh frequency affect all users that log on to the computer.
