no DVI signal during boot (POST) till Windows starts (Dimension 8400 + Radeon X800 SE)

I replaced my old 17"CRT monitor with a 22" LCD monitor Belinea B.display 4.1_22 wide.

For optimal quality I connected the Belinea monitor via DVI.

 

My problem :

There is no DVI signal during boot (POST) till Windows starts.

Analog connected (vga) the boot can be followed on the screen.

Because I have to choose between different hardware profiles, I really need to see this boot sequence.

 

On different forums I read about the existing of this phenomenon, but nowhere have I found a solution.

 

My system: Dell Dimension 8400 (10/2004)

Graphics card: Radeon X800 SE

 

Already done :

I loaded the latest computer bios upgrade (A09).

I loaded the latest Catalyst control center and Ati driver version.

In Catalyst, I activated in Digital Panel (DVI) attributes :

- Reduce DVI frequency on high-resolution displays

- Alternate DVI operational mode

 

Extra information from Catalyst :

Driver Packaging Version 8.471-080225a1-059746C-ATI

Catalyst® Version 08.3

 

Graphics Card Manufacturer Built by ATI

Does anyone know what company made the Radeon X800 SE card for Dell? Was it ATI?

I hope they didn't, because there is no service for older cards.

Has anybody a solution for this problem?

 

I DVI connected the LCD on another computer with Geforce card and the boot sequence was visible.

 

Many thanks for your help.
