I am using a DELL Optiplex GX270 system. This system has Intel 865G/Gl/GV graphics adapter which supports DDC/CI communication. After connecting a DDC/CI complaint monitor, I am not able to achieve DDC/CI communication on this machine. If I connect this monitor to a system with Intel 865G/Gl/GV with Intel mother board, it works fine. I want to know whether DELL Optiplex GX270 supports DDC/CI communication or not. The same results are observed on Optiplex GX280. Any kind of information on this will be of great help.
Thanks in advance.
