60 | (description | |
61 | "ddcutil can query and modify most external monitors' settings, such as | |
62 | brightness, colour levels, and input sources. Generally speaking, any setting | |
63 | that can be changed by pressing buttons on the monitor can be modified by | |
64 | ddcutil. | |
65 | ||
66 | ddcutil communicates directly with monitors implementing the Monitor Control | |
67 | Command Set (@dfn{MCCS}). It usually does so through the the Display Data | |
68 | Channel Command Interface (@dfn{DDC/CI}) protocol on the I2C bus, but can also | |
69 | communicate over USB as per the USB Monitor Control Class Specification. | |
70 | ||
71 | One particular use case is in colour profile management. Monitor calibration | |
72 | is relative to the monitor colour settings currently in effect, e.g. red gain. | |
73 | ddcutil allows colour-related settings to be saved at the time a monitor is | |
74 | calibrated, and restored when the calibration is applied.") | |
