We have an odd XFX Nvidia 7950GT problem that doesn't make any sense. About 2.5 years ago, we got 2 x Samsung 30" 2560x1600 model 305T Plus monitor and is connected to 1 x XFX Nvidia 7950GT, using it on a HP XW9300 professional workstation. We use the above seamlessly for 2.5 years, both the video card and the 2 x 30" monitors works fine.
Then last month, I inherit the above from my business partner, and move to a brand new HP ZR30W 30" 2560x1600 LCD monitor. Needless to say, both the HP ZR30W and the Samsung model 305T Plus are 30" 2560x1600 running on dual link cable.
My task is to phase out the Samsung 1 at a time, with the HP ZR30W as the 2nd monitor, and the Samsung 305T Plus as the primary monitor. Then eventually, get rid of the other Samsung, and use yet another ZR30W. Now, once connected, the brand new HP ZR30W doesn't work. The control panel see the HP ZR30W, but the screen is black, switching to the other DVI port, same thing.
Now, w/ my new computer, it has 2 x PCI Express x 16 slot, so I connected a 2nd XFX 7950GT nvidia card, and same thing. Then I assume HP has a DOA (Dead On Arrival) monitor. Send it back, got a 2nd one brand new, same problem. Then I sent back the 2nd one and got a 3rd brand new HP ZR30W.
Only this time, I didn't pick it up at the store, I ask the store to open the box and connects to 1 of their computer, and the HP ZR30W works. I then take the 2nd ZR30W that I returned to the store and ask them to try it, and it also works. So now I know there is some kind of compatibility problem between the XFX video card and the HP ZR30W.
But that same XFX 7950GT video card DOES WORK w/ the Samsung 305T Plus, which is also a 2506x1600 LCD.
The only difference between the 2 brand is that the Samsung is 2.5 years old, and the HP is brand new that c/w display port and DVI.
As of now, I am using a Quadro FX570, which is much slower than the 7950GT. With the 7950GT connects to 1 x HP ZR30W, 1 x Samsung 305T Plus:
1) During boot up, you don't see the BIOS screen on the HP, but you see it on the Samsung
2) If I turn off the HP during boot up, the XFX 7950GT DOES display the 2560x1600 just fine after win 7 boots up, but say if I turn off the HP (and the Samsung) temporary for say a few minutes (say if I'm on the phone), when I turn back on both monitors, all I get is a black screen on the HP, but the Samsung obviously is fine.
The only case that came close to the above, is a few yr. ago, when the XFX 7950GT was connected to 2 old 19" CRT monitor, 1 of the XFX 7950GT display just fine, but the other 7950GT display with some color band problem, and when we take that 7950GT to 2 x LCD display, everything works
Now, I really like this XFX 7950GT, as it is heat sink, and it c/w 2 x dual link. I like heat sink because there is no fan, it doesn't attract dust, and there is no noise. All the current XFX Nvidia cards has fan on it, so I just want the problem solve rather than replace it.
Is there a way to flash the EPROM on the XFX 7950GT?
And for now, the only solution that XFX told me is to take the video card and the ZR30W and connects it to another computer, to see if the problem can be duplicated, and I'll do it tomorrow.
