4 monitors ok, 5 monitors crashes media player, all video apps
On Windows Vista Premium (DirectX 10), applications such as Windows Media
Player 11, and the performance ' Windows Experience Index ' aspects that test
graphics ( WinSAT ? ) crash every time when there are 5 monitors enabled or
more. They all work fine when using any number less than 4. Of the seven
monitors connected to 4 graphics boards, the system works well with any four
of the seven and it always crashes video display applications when adding any
one or more of the remaining three. Monitors that crash Windows Media
Player 11 when added as the fifth monitor will work well when that same
monitor is one of only four.
It crashes the moment the video is to begin playing. Except for displaying
video, 7 monitors all work properly at high resolutions.
The system's graphics have 2 NVidia GEForce 8600's, and 2 NVidia GEForce
6200 boards. It does not matter which of NVidia's drivers are loaded,
whether WHQL, latest release or Betas. 32 bit or 16 bit pixel color depth.

I've downloaded such related hotfixes as I could find, no change.
Is there a registry setting change I can make? The system is supposed to be
a high volume video editing workstation. The user has a hard time accepting
why all seven monitors appear to work, but when it's time to actually use
Vista for what it supposed to be used for, three of the seven monitors have
to be disabled.
