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 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.
