2. Intel DPST subsystem applies an image-specific enhancement to increase image
contrast, brightness, and other attributes.
3. A corresponding decrease to the backlight brightness is applied simultaneously to
produce an image with similar user-perceived quality (such as brightness) as the
original image. Intel DPST 5.0 has improved the software algorithms and has minor
hardware changes to better handle backlight phase-in and ensures the documented
and validated method to interrupt hardware phase-in.

Automatic Display Brightness
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 back light setting.

Seamless Display Refresh Rate Switching Technology (Intel
®
SDRRS Technology)
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 on plugged in power 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 design application is on battery power and
when the user has selected/enabled this feature.

when the user has selected/enabled this feature.
There are two distinct implementations of Intel SDRRS – static and seamless. The
static Intel SDRRS method uses a mode change to assign the new refresh rate. The
seamless Intel SDRRS 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.

Disabling Unused System Memory Outputs
Any system memory (SM) interface signal that goes to a memory module connector in
which it is not connected to any actual memory devices (such as DIMM connector is
unpopulated, or is single-sided) is tri-stated. The benefits of disabling unused SM
signals are:
