If it isn’t, make sure that you turn it On.
Press the physical Settings button on your monitor, look through the settings to see if DDC/CI is enabled.
Here’s a quick guide on how to enable, install and configure DDC/CI using ClickMonitorDDC: You’ll have easy access to your monitor’s controls at any time just by clicking on the software’s notification icon (in the Taskbar Tray area). This is ideal those cases where you’re using a multiple monitor setup (from different manufacturers) – DDC/CI will allow you to gain control over all your active displays.ĬlickMonitorDDC is a portable freeware tool that will allow you to adjust the brightness and contrast of any DDC compatible monitor just by adjusting a series of sliders.
If you’re looking for a universal program that will allow you to use DDC/CI regardless of your monitor manufacturer, we’ve got you covered. There are some monitor manufacturers that have developed their own proprietary software that works with DDC/CI (such as Samsung MagicTune), but that obviously won’t work with monitors outside Samsung’s sphere. But if you’ve purchased your monitors in the last 3-4 years or so, DDC/CI should be supported. In order to use DDC/CI, you first have to ensure that your monitor is capable of supporting it. Some DDC/CI monitors can even support the auto-pivot technology – a rotation sensor built inside the monitor allows it to keep the display straight even if the monitor is physically moving in horizontal and vertical positions. The command Command Interface (CI) is the channel that the two involved parties (the computer and the monitor) are using to send and receive commands to each other. A lot of monitor models will have less than intuitive user interfaces, so it’s understandable why some users are looking for ways to avoid using the clunky buttons that many monitors models have. On a very basic level, DDC/CI provides the Plug & Play functionality to the monitor. But even more important, a display data channel allows the user to oversee and change monitor features such as the brightness, contrast and color palette directly from their computer. It holds a collection of protocols used to facilitate the transmission of display-related information between the computer display and the display adapter.ĭDC essentially allows the monitor to inform the computer about it’s supported display modes. Display Data Channel / Command Interface (DDC/CI) What is DDC/CI?ĭisplay Data Channel (DDC) / Command Interface (CI) is a type of communication between the computer and the monitor. This is partly because most monitors manufacturers are not inclined to develop proprietary software for it. Most monitors today will support a neat feature called DDC/CI, but not many people have heard of it, let alone know what it’s for or how to use it.
