2005FPW DVI Problem: Cannot display this mode during BIOS

Question

The 2005FPW worked perfectly for about a month, but last night when I rebooted the comp... I wanted to enter bios but the LCD would not display the bios. The LCD was reading that hte computer was on and the lcd was not in sleep mode. It gave me the message: [2]: DVI, Cannot Display This Mode But if I leave it alone, it will boot into winxp pro and at that point, the lcd works fine. I have tried the VGA connection and that worked fine. Shows me bios and all. But when i used the DVI again, it gave me that message. I am thinking it's either the DVI cable itself or the DVI connector on the LCD. I do not have another DVI LCD to test the latter theory on. My Specs: Sempron64 2800+ ABIT NV8 1gig of PQI PC3200 ram (2x512mb) XFX Geforce6600gt 128mb PCI-E with dual dvi output Would dell replace my DVI cable if i find that it is the culprit to my problem? What else is there to do?

I have seen a few post that there is no resolution to this. When you need to enter BIOS, just connect with the VGA cable.

I realize this was posted awhile ago but...
This problem usually caused by the bios deciding that the VGA port is the initial or priority display. Then once windows starts it recognizes the other outputs.
I have an ati aiw 9800 and it displays the bios screen only on the component out port which is suppose to be the secondary display. Once windows boots it appear on my desktop monitor.
So if I want to see it boot I have to turn on my big screen tv to that input. Strange
I know. I did find out a way around it was to pull the dongle for the secondary display and then the dvi/VGA will become the primary. I found that nothing in the bios could change this behavior.

I learned to live with it as generally if there is a problem the post test will tell me. If the problem is serious meaning I will have the ambition to move the box and get into the mass of wires at the back of the case. Check out your video card settings to see if there is a way of making the dvi as the primary display on bootup and check the makers or enthusiast website for support on such a problem.
