AOC G-Menu vs ddcutil

AOC G-Menu is a free Windows portal for customizing supported AOC gaming monitors and peripherals, including keyboards, mice, mouse mats and headsets. Its settings include keyboard macros and mouse sensitivity adjustments. Light FX lets users choose effects, colors, pulsation and brightness for compatible devices, while Light FX Sync coordinates RGB effects across them.

Users can save multiple game profiles and switch between them, or associate a profile with an executable so its application runs when that profile is selected. Discover lets users find and share game profiles. The Macro interface supports recording, editing, importing and exporting macros. G-Menu checks for software updates from its home page and downloads available updates in the background; it cannot check without a network connection. The interface offers only connected devices. The manual lists Windows 7 or above, 500 MB of free hard disk space and an internet connection as requirements. AOC provides a Windows download and a manual.

ddcutil is a free Linux program for controlling monitor settings such as brightness, color levels and input source. It communicates with monitors through DDC/CI over I²C and supports monitors implementing MCCS over USB. Commands can find monitors, show capabilities, read or change VCP feature values, and save or restore color-related settings. The companion ddcui provides a Qt graphical interface with Summary, Capabilities and Features views, with the last allowing changes to modifiable values. For profile workflows, dumpvcp saves current settings to a file and loadvcp restores them. Developers can use the C API through libddcutil.so to read and write VCP values and handle profile-related features. The program is released under GNU GPL version 2. Setup requires the Linux kernel i2c-dev module, and non-root users need permissions to run it. It does not support laptop displays, which use a special API rather than I²C, and generally will not run in virtual machines because virtual video drivers do not implement I²C. For MCCS-over-USB table features, support is limited; the capabilities command synthesizes a response.
