Thank you a lot for supporting and answer

I brought many DP cables the last one is VESA certified in first use the monitor kept flickering and make sound i frustrated , when i used second time i blow the ends to remove dust if exist in ends cable's and put it tight in ports the cable works excellent

the conclusion of my experience with Displayport is :

1- use VESA certified cable.

2- make sure the ends cable are clean and no dust .

3- put the cable tight in monitor and PC

Try a different DP cable.  Preferably not the cheapest, but more of a name brand.  One that's VESA Certified may be optimum.  I've had defective generic brand new cables before.

but when i removed the Graphics driver the problem is gone

I'm not sure if it's the monitor or not. May be try Dell Support Assist to make sure drivers are updated?

Also, how do you want the monitor hooked up? If it works on HDMI...

Also, it's a brand new monitor, right? May be chat or call Dell directly as it is under warranty.
