When Intel's Display Power-Saving Technology is enabled, the screen may automatically change the screen's brightness depending on what content is being displayed. The next section will explain why this is happening or you can go straight to the last section for troubleshooting steps to disable this function.
Intel Display Power Saving Technology (DSPT) is a power-saving feature in Intel’s latest version of mobile graphics chips. These graphics chips reducing power consumption on the computer by altering the brightness and contrast of the display.
What does this mean?
Intel DPST controls the LCD backlight, by reducing the backlight as needed they can save power. This can be important on mobile computers running off the battery. The aim is to automatically reduce the backlight brightness while maintaining good visuals on-screen. It analyzes the image to be shown, and it uses equations to change the chroma value and reduce the brightness of the backlight simultaneously. This means you should not see any distortion to the image on-screen. Intel says that 70% of the power that the backlight uses when watching media is saved.
This constant readjustment, however, is noticeable to some people, especially if they often change between different applications and media. The next section will take you through disabling the function. We only recommend doing this if you are seeing issues with this technology.
