In their own words
DDCcontrol
DDCcontrol is free Linux software for changing monitor brightness, contrast, color levels and other settings through DDC/CI. It offers a GTK interface for graphical control and a command-line tool for terminals, scripts and automation. Communication uses Linux’s i2c-dev interface and /dev/i2c-* devices, which must be readable and writable before monitors can be configured. USB-connected DDC/CI displays are not supported yet. A monitor database is required for monitor-specific controls and proper operation. The ddccontrol-scanmonitor utility reads a connected display’s EDID, capabilities and supported controls, and can generate a monitor database XML file; scanning does not alter control values. The maker’s database index lists 474 monitor profiles in release 20260928. Packages are listed for Debian/Ubuntu, Fedora and openSUSE, alongside source releases and source builds. The project uses the GNU General Public License version 2.0 and directs support questions to GitHub Issues.
LG OnScreen Control
LG OnScreen Control is a desktop utility for managing features on certain LG monitors from Windows or macOS. It offers Screen Split, which divides the display into regions, and controls for brightness, contrast, and other monitor settings. My application Preset can change picture mode when you click a chosen application window, while Game mode settings let you adjust game-related monitor settings. The 5:9 Preview feature displays an application in a 5:9 area that you can move to a preferred position. The app can also update monitor firmware. A USB connection is required for settings and firmware updates; firmware updates also need internet access and a supported USB cable. Support depends on the monitor model, so LG advises checking its owner’s manual. The app does not support the PC’s Duplicate display setting; LG advises using Extend mode if its menu does not appear. A non-genuine cable or adapter can prevent DDC/CI communication, and using a third-party monitor may limit some features. The download is free for supported models.
