Troubleshooting

If DDM cannot work with your monitor, DDM will show the following icon in your
notification tray.
Click on the icon, DDM 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 steps to troubleshoot:
1. Make sure the video cable is properly connected to your monitor andyour 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.
