Hi Roman,
That would be ideal but our processors and most of them do not have genlock options. That being said, so far our processors have not caused any issues. We are able to have scenarios where both processors are in sync. That depends of what we put in front of them.
Speaking of:
Daniel, we made 2 other tests today. I did not have a DVI DA handy but I used the Loop out of the LED processor 1 to go in the 2nd LED processor.
1 computer -> 1 output -> into 1 LED processor -> Loop out to 2nd LED processor -> To 2 LED screens.
Version 1 is with our line and frame # video file
Version 2 is with a flashing white image playing in a video file. (see link below)
https://drive.google.com/folderview?id=0B4VkNuY3RAt3RHFSSG9IU2V0dFE&usp=sharingEverything was in sync which confirms that our LED processors do not affect the signal or its vertical sync.
We made several tests where it was obvious that things were no longer in sync. For example, when we make the signal go through a Crestron DM-MD 128x128 matrix we loose our sync. We are currently in discussion with them to see if this can be corrected. As soon as we bypass the matrix, we can be in sync again.
So to come back to our main question, when we have 2 computers (each with 1 output from a Quadro M4000 and a Quadro Sync card which are synced (Frame locked) to one another (master - client)) and FluidFrame at OFF we do not get a synced signal. The Nvidia manual suggest that we put vertical sync ON when we Frame Lock quadro cards. We tried with 2 scenarios (Vertical sync ON and Vertical sync = Let 3D application decide) and in both cases we were not in sync.
Does that mean that Quadros and Quadro sync cards are not doing their job? Is there an incompatibility with Coolux? Is there a setting in the graphics cards that we need to change? Is FluidFrame Necessary for sync to take place? To me it seems that it should not be necessary when using Frame Locked video cards.
What do you think?
If you'd like to have our video test files, I'm happy to send them to you. Note that they are in 30 fps since we are in 60hz. We could probably make a 25fps version if needed.
Thanks.
