Sapphire 5850: Native DisplayPort (No Adapter) + Startup = No Post

[magikempire]

All:

Background:
I need to tap the ATI gods here at Xtreme Systems for some help. Last week I bought (3) Dell UltraSharp U2311H Monitors. These have native Displayport, DVI, VGA.

The Video Card I have is an ATI Sapphire 5850 1GB Game Edition. To setup Eyefinity I have connected two of the monitors to DVI and the 3rd monitor to DisplayPort using a DisplayPort Cable (No active adapters since this is DisplayPort to DisplayPort).

Problem:
When the DisplayPort monitor is plugged in nothing posts. The video card fan goes to 100% and video card never enables a monitor, the system looks to be starting as if the process goes far enough since I get a "Windows Boot Normal?" message on the next successful boot.

What have I tried?
1. Emailing Sapphire Tech, response about lowering Fan speeds in CCC (obviously not going to work), ticket still open
2. Updated GPU Sapphire BIOS, no change (Tech Powerup Versions)
3. Updated to GPU MSI BIOS, no change (Tech Powerup Versions)
4. Updated to GPU ATI BIOS, no change (Tech Powerup Versions)
5. Updated Motherboard BIOS, no change
6. Played with PCIE Timings (100Mhz to Auto), no change


Any suggestions on what I could do now?

I seem to be at a loss for more ideas on this since a DisplayPort Monitor should work right out of the box with a straight cord, or at least one would assume.

Big Thanks for Helping!
