==System Environment==
--------------------------
DP monitor: ASUS PA238Q
BIOS: V59 
Regression: No. Tried on drm-intel-testing-2015_01_30 and still saw this issue.
This is weird since I saw PA238Q DP screen worked before. This machine was
reworked and the DP screen is black too when I tried to enter into BIOS
setting. 

Non-working platforms: BSW

==kernel==
--------------------------
-testing: drm-intel-testing-2015-03-27 (fails)

==Bug detailed description==
-----------------------------
When connected to ASUS PA238Q with DP cable and booted system, DP screen is
black.

If I connected to Dell U2311Hb, DP screen works.

==Reproduce steps==
---------------------------- 
1. Disconnect eDP, Connect ASUS PA238Q with DP cable and boot
