三、Technical Principle Explanation

Note: Lunar defaults to software-level brightness adjustment.

• Main Method: Achieving software dimming of screen brightness by calling the system gamma table (Gamma Table).
• Backup Solution: Simulating the effect of reduced brightness when the gamma table is unavailable by using a dark overlay layer.
• Important Difference: This mode does not directly control the hardware brightness of the display through the DDC/CI protocol. Therefore, it does not alter the actual hardware backlight or settings of the display.

四、Hardware Control Recommendations

If you need to directly adjust the physical hardware brightness, volume, or input source of the display, we recommend visiting the Lunar official website to learn about other dedicated applications provided by the software, which may utilize DDC/CI for hardware-level control.
