To adjust the brightness and contrast of your laptop, here are some suggested steps and best practices:

1. Decrease the ambient room lighting as much as possible. A dark room is preferable when making brightness and contrast edits.
2. Access your laptop’s display settings. This can typically be done through the main Settings application, or via the graphical user interface of the display drivers.
3. Adjust the brightness hovering slide to your comfort level – adjust it until the desired level is reached.
4. Next, adjust the gamma (contrast) setting – adjust until the desired level is reached.
5. Once you are happy with the adjustments, double check to ensure that text, graphics, and videos are clearly visible.
6. When finished adjusting, exit the Settings application.
