Check your display driver, cables and connections. Please note that Dell Display Manager only works with Dell-branded monitors. If you are using monitors from other manufacturers, Dell Display Manager does not support them. If Dell Display Manager 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 graphics card driver from the graphics vendor (Intel, AMD, NVIDIA, etc.). Graphics card driver is often the cause of Dell Display Manager 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 Dell Display Manager. Update the driver of such device if the latest version is available. 5. Restart your computer. 12 | Troubleshooting
