....... just posted a huge post and i lost it. GFD reposting.


Simply cut down.
I'm using 2x ATI 6870s and 3x samsung 23" px2370s.
If you use an Nvidia card, you have to have a 2nd card to use 3+ displays.
If you use an ATI card, you have to have an ACTIVE display port adapter.
The ATI cards only pull enough power to power 2 of the hdmi or dvi ports. Attempting to use the third port will simply not work. Also, the active display port adapters come with a display port plug and a usb to draw additional power from the mother board. I suggest plugging that into any generic USB power adapter if you wish to have consistent power to your monitor without flickering.

Any further questions, let me know.
