Please note that DDM only works with Dell branded monitors. If you are using monitors from other manufacturers, DDM doesn't support them. If DDM is unable to detect and/or communicate with a supported Dell monitor, please take below actions to troubleshoot: 1. Make sure the video cable is properly connected to your monitor and your PC, especially the connectors should be firmly inserted into position. 2. Check the monitor OSD to ensure DDC/CI is enabled. 3. Make sure you have the correct and latest display driver from the graphics vendor (Intel, AMD, NVIDIA, etc.). Display driver is often the cause of DDM failure. 4. Remove any docking stations or cable extenders or converters between the monitor and the graphics port. Some low-cost extenders, hubs or converters may not support DDC/CI properly and can fail DDM. Update the driver of such device if the latest version is available. 5. Restart your system. DDM may not work with below monitors: • Dell monitor models earlier than year 2013 and D-series of Dell monitors. You can refer to Dell Product Support websites for more information • Gaming monitors using Nvidia-based G-sync technology • Virtual and wireless displays do not support DDC/CI • Some early models of DP 1.2 monitors, it may be necessary to disable MST/ DP 1.2 using the monitor OSD If your PC is connected to the Internet, you will be prompted with a message when a newer version of DDM application is available. It is recommended to download and install the latest DDM application. You may also check for new version by right clicking on DDM icon while pressing and holding 'shift' key.
