In most cases, however, monitor settings are changed through the operating system. Mac and PC systems make it relatively easy to access and adjust these settings.

The display settings are where changes are made to brightness settings, screen sizes and more. This area even allows for settings controls on multiple monitor systems.


After accessing the Display controls, select the appropriate monitor if multiple are attached to the system. If not, only one option is available. Choose the resolution drop-down box and select the preferred resolution setting. Click Apply to make the change permanent.

Consider implementing the auto-adjust settings feature while making changes in the control panel and display settings. This will ensure the monitor changes brightness gradually according to the light outside and battery life. It also eliminates the need to constantly make adjustments based on the amount of light outside. In a stable light setting like an office with overhead lights, this becomes less important.
