Troubleshooting If DDM does not work with your monitor, DDM will show the following icon in your notification tray. Click on the icon, Dell Display Manager shows a more detailed error message. Please note that DDM only works with Dell-branded monitors. If you are using monitors from other manufacturers, DDM does not support them. If DDM is unable to detect and/or communicate with a supported Dell monitor, please take the following actions to troubleshoot: 1. Make sure the video cable is properly connected to your monitor and your computer, 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 computer. DDM may not work with the following monitors: • Dell monitor models earlier than year 2013 and D-series of Dell monitors.
