Default Override DPCD information

Greetings,

I'm trying to solve a problem where a Quadro NVS 450 cannot determine the proper DisplayPort link rate, lane count, and pixel clock speed, when the monitors are turned off. Is there a way to override these parameters in the xorg.conf?

Here is a snippet from the Xorg log when the monitors are off:

Code:
(WW) Oct 11 15:39:28 NVIDIA(GPU-0): DFP-2: Failed to read DPCD
(II) Oct 11 15:39:28 NVIDIA(GPU-0):     Maximum link rate:   1.62 Gbps per lane
(II) Oct 11 15:39:28 NVIDIA(GPU-0):     Maximum lane count:  1
(II) Oct 11 15:39:28 NVIDIA(GPU-0):     Maximum pixel clock: 71.287 MHz

Here is a snippet from the Xorg log when the monitors are on:

Code:
(II) Oct 11 15:52:53 NVIDIA(GPU-0): DFP-2: DisplayPort revision 1.1
(II) Oct 11 15:52:53 NVIDIA(GPU-0):     Maximum link rate:   2.70 Gbps per lane
(II) Oct 11 15:52:53 NVIDIA(GPU-0):     Maximum lane count:  4
(II) Oct 11 15:52:53 NVIDIA(GPU-0):     Maximum pixel clock: 475.248 MHz

Thank you.
