Dell UltraSharp U3415 has vertical lines across the entire screen

Installed Monitor to Computer on September 11 2015.  I hooked it up to my computer via DP to DP and after 45 minutes the screen was covered with white and green vertical lines.  I switched out the cable to the HDMI to HDMI with same result.  Attached to another older Alienware Aurora R4 with a AMD Radeon HD 7800  with same result.  Is this defective or is it settings?

Performed Hard Reset

Reviewed the manual
