HPZR30w monitors blink intermittently

I have one hp 3065 monitor and 3 HPZR30w monitors. The 3065 has no problems but the HPZR30w monitors blink intermittently, from one blink per 5 hours to one blink per 10 minutes. The blink is a flash to black then back to normal.
I am running 2 hp3800 nvidia cards in a Z800 workstation.
HP has replaced the monitors, video cards, powersupply, and system board.
They can't figure out how to fix this problem.
Can anyone help me?

GeoCFI, ,
Sounds like a power issue, maybe a momentary lag in power, how you do you have these 3 monitors connected to a power source?
On a power board all together or with some other hardware, if an airconditioner cycles on may interfere? Or some other hardware.
The fact it occurs simultaneously on 3 monitors could be the connection/cabling to the board is faulty or loose??
Heat issues.
Could you describe the connection, 2 monitors on each card?
My line of thinking 1 monitor differs from 3.
If all were the same brand?
I dont know how one would diagnose this apart from testing two monitors at a time with the same brand.
Run windows 7 resource monitor live on the desktop at all times.

So you have - NVIDIA Quadro FX 3800? Try the latest full nVidia driver rather than the HP version.

I tried all of the above and none of them helped, HP is sending me a new computer, in the meantime, don't buy HP, buy Dell or any other brand.
HP techs don't have any idea what's going on.
