How to adjust monitor brightness
When using your computer on a daily basis, your monitor's brightness setting is critical to eye health and your visual experience.

|---|---|
| Eye fatigue and dryness | Reduce or increase brightness based on ambient light |
| Color distortion | Use standard mode or calibration tools |
| Increased energy consumption (excessive brightness) | Adjust to energy saving mode |
2. How to adjust the monitor brightness?
How to adjust your monitor brightness varies by device and operating system. The following are the steps to adjust the brightness of common devices:
| Device type | Adjustment method |
|---|---|
