Quadro fx 1500 will not do 2560x1600

Hi everybody,

I have become the proud owner of a HP ZR30w Monitor. My graphics card (Quadro FX1500) however refuses to drive the thing at the native resolution of 2560x1600. It only works at half-res of 1280x800.

Here is a brief list of what I have done so far:

- Installed every available quadro driver package
- Exchanged identical quadro cards (work/home)
- Put cards into different computer
- Swapped dual-link DVI cables
- Installed a fresh copy of Winxp 64 on a spare drive and ran the system from it
- Had the monitor panel exchanged by HP (drastic, I know ...)


This card is supposed to drive two (2) of these displays.

I don't know what else to do.

Any help would be greatly appreciated.

Thank you.

 

quick question what happens when you turn the res up? or is that not an option?

2560x1600 is visible as an option in the nvidia control panel, and I can switch the monitor to it, but it results in a practically black screen. Not pure black as when the screen is of, but "lcd-black" with the screen is on and showing the color black ...
