dell U2414H REV A02 DP issue

Hello there.

Today i bought this monitor. I was excited till when come home and start connect the monitor.

Display Port stop receive signal from computer after install fabric CD driver that comes inside the monitor pack.

I have notice that CD is from the same model but with REV00 ... and i have installed, without previous knowledge, that DELL MONITOR DRIVER that comes inside that CD.

After that... Monitor wont show image from display port cable. BLACK IMAGE. I have try everything.

The only way to get image is from HDMI... but i buy this monitor special for it DP connection.
 
I need help to get back. And solve this. I bought this for work, and i just spend 1 entire day to search for solution.

i have a nvidia GTX780M (display port 1.2) and an INTEL HD 4600
