U2713H not recognized by Dell Display Manager
Dell Display Manage used to work for me. It was a good tool to divide my windows tab into 3 parts. However after a few months i forgot to use DDM, and now when i run it can't recognize my monitor.
Attached is the self-diagnostic report.

Try this: go into the U2713H OSD menu and under "Display Settings" change "DisplayPort 1.2" to Disable. Also make sure DDC/CI is enabled under "Other Settings".
You may need to power cycle the monitor, and restart DDM.

Thanks, that worked. Do you know why it happened? Also isn't DP 1.2 supposed to be better than DP 1.1?

Its a known hardware issue with Uxx13 models, noted in the DDM release notes:
- with first generation DP 1.2 monitors, it may be
necessary to disable MST/DP 1.2 using the monitor OSD
With these monitors, DP1.2 is "better" (and required) only if you need to daisy chain additional DP monitors off the first.
