#Dell ddc ci software
Most monitors today support DDC/CI, but not many people have heard of it, since most manufacturers do not develop proprietary software for the feature.Īnd ddcbc-gtk is a free open-source GTK tool for controlling brightness through the DDC/CI protocol. Found I2C device (dev:/dev/i2c-4)Have a computer monitor supports DDC/CI protocol? There’s now a free and open-source graphical tool to control the brightness of your display.ĭisplay Data Channel ( DDC) / Command Interface ( CI) is a type of communication between the computer and the monitor. With 8800GT NVIDIA drove my display just fine. So seems like this issue related to monitor rather than driver. But on another display Acer AL2216W is not working.
I have DELL 2407WFPHC display on which its working fine.
