I doubt that the monitor hardware is defective. Open the U2414H OSD (On Screen Display) Display Settings and make sure DisplayPort 1.2 is disabled.

* Turn the monitor off
* Turn the computer off
* Disconnect/reconnect ALL of the cables =
Computer Asus HD7750 DP out --> Dell U2414H DP to mDP cable --> U2414H mDP in
Computer USB port --> U2414H USB upstream cable --> U2414H USB upstream port
* Turn the monitor on
* Turn the computer on

DDM is not supported with DP 1.2 enabled. Why, no idea. The software manufacturer (entech) would have to tell us.

From the DDM release notes:
Troubleshooting
----------------------
If DDM is unable to detect and/or communicate with
a supported Dell monitor:
- make sure you have the correct and latest display
driver from the graphics vendor (AMD, Intel, NVidia)
- check the monitor OSD to ensure DDC/CI is enabled
- remove any docking stations or cable extenders or
converters between the monitor and the graphics port
- with first generation DP 1.2 monitors, it may be
necessary to disable DP 1.2 using the monitor OSD
