Dell Display Manager Error This program requires a supported Dell monitor and connection, and compatible display driver. Dell Display Manager 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 below actions to troubleshoot: 1. Make sure the video cable is properly connected between your monitor and your computer. Ensure the connectors are firmly inserted into position. 2. Check the monitor OSD to ensure DDC/CI is enabled. 3. Make sure you have the right graphics card driver from the vendor (Intel, AMD, NVIDIA, etc.). Graphics driver is often the cause of DDM failure. 4. Remove any docking stations, cable extenders, and 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.
