My configuration is composed by 5 Workstation, using a FirePro V7900 and a FirePro S400 each.
Each workstation is connected to 4 projectors (arranged using Eyefinity) running at 120hz.
Alle S400 cards are connected to each other using Ethernet Cables and configured like a chain.
An Optoma RF emitter is connected to the Workstation configured as Sync server to use shutter glasses.
I'm using the driver version 9.003.3-121120a-150766C-Retail (tested even with two previous versions).
The problem is that running a Stereo application, frames between cards are not synchronized to eye:
All projectors connected to the same card are perfectly synchronized, but the synchronization between workstation doesn'y work well (Right/Left Eyes between workstations can be swapped).
After the application is started, the synchronization is mantained, but images concerning Right/Left eyes are swapped.
Every time an application starts, the Right/Left eyes configuration between workstations is random, but is mantained during the running.
The configuration of synchronization chain is good (because when it's not active I can see wrong colors using shutter glasses).
(The workstaion running as Server is always correct).
Tests are made using an OpenGL application which clears a windows using blue for GL_BACK_LEFT and red for GL_BACK_RIGHT, so using shutter glasses I can see the synchronization,
Is there a reason for this behaviour? What's wrong?
