Intel i7-4600U CL8064701477000 Data Sheet

The Intel Automatic Display Brightness feature dynamically adjusts the backlight

brightness based upon the current ambient light environment. This feature requires an

additional sensor to be on the panel front. The sensor receives the changing ambient

light conditions and sends the interrupts to the Intel Graphics driver. As per the

change in Lux, (current ambient light illuminance), the new backlight setting can be

adjusted through BLC. The converse applies for a brightly lit environment. Intel

Automatic Display Brightness increases the backlight setting.

When a Local Flat Panel (LFP) supports multiple refresh rates, the Intel Display

Refresh Rate Switching power conservation feature can be enabled. The higher refresh

rate will be used when plugged in with an AC power adaptor or when the end user has

not selected/enabled this feature. The graphics software will automatically switch to a

lower refresh rate for maximum battery life when the notebook is on battery power

and when the user has selected/enabled this feature. There are two distinct

implementations of Intel DRRS – static and seamless. The static Intel DRRS method

uses a mode change to assign the new refresh rate. The seamless Intel DRRS method

is able to accomplish the refresh rate assignment without a mode change and

therefore does not experience some of the visual artifacts associated with the mode

change (SetMode) method.
