I'm running a HP Z800 with 24 gigs of ram, 2X3.33 cpus, 4 HP 30 inch monitors with Windows 7.
My video cards are HP nvidia FX4800.
3 of my monitors are HPZR30w and one is a HP3065.
The HPZR30ws are using display port and the 3065 is using DVI.
The 3065 will not display with the 3 HPZR30ws plugged into the video cards.
It's not the cables or video cards, they have all been replaced.
My power is good the power supply has been replaced.
I'm using battery backups so I know I don't have a ac power problem.
Anyone have any ideas why this is not working?
I really need your help on this.

Hi,

Are you plugging the 3065 in using the DP to DVI adapter on one of the cards or the DVI port?

Regards.

Hi,

If you are using DisplayPort to DVI, are you using an active DP to Dual-Link adapter?

If using DVI, is the cable a dual-link cable?

Regards,

The cable is dual-link and I'm using an active usb powered adapter.
The 3065 is now working since I started using the powered adapter, but some of the z30s still blink intermittantly. (flash black for an instant, about 1/100 of a second) then back to normal.

Hi,

Seems the blinking problem is an issue with that monitor:

HP is sending me a new computer.
In the meantime, don't buy HP, you will be happier with Dell.
HP has been jacking me around for 6 months on this.
Their hardware reps can't even change a system board.
And they don't even know Windows 7.
