![]() And like Lunar developer notes, this GPU derived from that of the iPhone or iPad does not support the DDC standard, since Apple did not need it. ![]() Use Apple Keyboard keys or custom shortcuts. Control your displays brightness & volume on your Mac as if it was a native Apple Display. But this is no longer the case with Apple Silicon Macs, which now rely on the in-house GPU built into the Apple M1. Monitorcontrol is an open source software project. Macs using GPUs integrated into Intel processors or graphics cards from AMD, they benefited “for free” from this option. Apple has not integrated the DDC, it is Intel or AMD who did it in their graphics chips. This possibility was linked to the choice of standard components for Macs. However, third-party apps could use DDC to reproduce the operation of Apple screens with monitors from other brands, including keyboard brightness control. This is also what is used for LG UltraFine screens that Apple has been selling on its store for a few years. Control your external monitor brightness, contrast or volume directly from a menulet or with keyboard native keys. For its screens, the company has developed its own USB communication protocol. It’s a standard, but Apple has never supported it. For third-party screens, a third-party app must be installed and only Intel Macs are compatible. Only Apple-designed screens have brightness control from macOS, in System Preferences and on the keyboard. Supported Platforms¶ Linux (tested with Ubuntu desktop 20. ![]() DDC is available with DVI, DisplayPort and HDMI connections, which means it’s also found on USB-C displays. monitorcontrol¶ Python monitor control using the VESA Monitor Control Command Set (MCCS) over the Display Data Channel Command Interface Standard (DDC-CI). In the case of a computer screen, the source is the graphics card, and the controls are used to adjust the brightness or even the contrasts. This VESA standard establishes a digital connection between a display and the source, which allows the source to send commands to a monitor. To change the brightness of third-party screens, these apps use DDC, for ” Display Data Channel “. Their developers are not responsible, this incompatibility is explained by a function missing from the GPU of the Apple M1. This is the case of Lunar, but also of MonitorControl and all similar apps. Use Apple Keyboard keys or custom shortcuts. Control your external monitor brightness & volume on your Mac. The three Apple Silicon Macs currently on the market are incompatible with all apps that allow you to change the brightness of screens that were not created by or for Apple. Control your displays brightness & volume on your Mac as if it was a native Apple Display.
