(description
|

"ddcutil can query and modify most external monitors' settings, such as
|
|
brightness, colour levels, and input sources. Generally speaking, any setting
|
|
that can be changed by pressing buttons on the monitor can be modified by
|
|
ddcutil.
|
|
|
|
ddcutil communicates directly with monitors implementing the Monitor Control
|
|
Command Set (@dfn{MCCS}). It usually does so through the the Display Data
|
|
Channel Command Interface (@dfn{DDC/CI}) protocol on the I2C bus, but can also
|
|
communicate over USB as per the USB Monitor Control Class Specification.
|
|
|
|
One particular use case is in colour profile management. Monitor calibration
|
|
is relative to the monitor colour settings currently in effect, e.g. red gain.
|
|
ddcutil allows colour-related settings to be saved at the time a monitor is
|
|
calibrated, and restored when the calibration is applied.")

"The MSR Tools project provides console utilities to directly access the

Model-Specific Registers (@dfn{MSR}s) and CPU ID of Intel-compatible processors:
|
|
|
|
@itemize
|
|
@item @command{cpuid}: show identification and feature information of any CPU
|
|
@item @command{rdmsr}: read MSRs from any CPU or all CPUs
|
|
@item @command{wrmsr}: write to MSRs on any CPU or all CPUs
|
|
@end itemize
|
|
|
|
These tools can be used to query and modify certain low-level CPU parameters,
|
|
such as the Turbo Boost ratio and Thermal Design Power (@dfn{TDP}) limits.
|
|
|
|
MSR addresses differ (greatly) between processors, and any such modification can
|
|
be dangerous and may void your CPU or system board's warranty.")
