Though the default settings of your Dell laptop monitor will probably work just fine, it can be worth it to manually calibrate your laptop monitor. Doing this allows you to specify settings such as resolution and color quality. Calibrating your Dell laptop monitor can make sure you're getting the absolute best picture quality for your own personal standards. Calibrating a Dell laptop monitor can be done using a utility built into the Windows operating system.
Right-click anywhere on the Windows desktop. Select the option that reads "Properties" from the drop-down menu that appears.
Click on the "Settings" tab from the "Display Properties" window.
Slide the bar under the "Screen Resolution" heading until the settings are to your liking. Press the "Apply" button to see your changes. You can always change them back if you don't like the way your monitor now looks.
Use the drop-down menu under the "Color Quality" setting to specify what "bit-rate" of colors you'd like your monitor to display. You can choose between 16-bit color and 32-bit color. Hit "Apply" to see your changes.
Hit the "Advanced" button to change options relating to the power settings of your monitor. You can specify things such as how long your monitor will sit idle before it automatically shuts itself off as well as brightness settings. When finished, hit the "Apply" button to force your changes into effect. Hit "OK" to save these changes and exit back to your Windows desktop.
