Make sure the video cable is properly connected to your monitor andyour PC, especially the connectors should be firmly inserted intoposition. 2. Check the monitor OSD to ensure DDC/CI is enabled. 3. Make sure you have the correct and latest display driver from the graphicsvendor (Intel, AMD, NVidia, etc.). Display driver is often the cause of DDMfailure. 4.
