Hi, I need help with a 4 monitor setup. I have an HP z400 workstation with two PCI-E slots. I tried a Nvida Quadro FX 1800 and PNY GT9500 and that only ran 3 monitors. I then tried 2 of the FX 1800 and that only ran 3 monitors as well. I have spent a lot of hours with CDW tech support and still no luck. I need the Experts for this one. I need to run 4 HP 24" monitors.
Thanks

A Pair of FX1800 should work, what I would say is that you should use display port to DVI cables end to end and not adapters. The only other potential pitfall would be wether the PSU has enough juice to power everything in you system.

So if I have 2 display ports on each card, and I have display ports on the monitors I just need to use 2 monitors to each card using the display ports. That might have been the issue since I was using the DVI to display port adapter. I am not by the PC now so I will have to try this when I get back to work. Any feedback is appreciated until then. Thanks

That worked. That was the issue. Both cards have two display ports so I did display ports to display ports on the monitors and it worked great. You saved me a lot of time with this. A 3 hour tech support call did not even solve it. Thanks again the the Experts.
