Our servers are the new MAC pros with 2GB RAM, 128GB SSD, and X1900XT Video.

In considering future projects, I think that the Tripple head is an interesting potential solution but I am concerned that we'll be a bit limited in resolution as well.

Hi Scott,

i´m really happy to hear from you. I hope that all the things are running fine for you as well.
Regarding the spyder issue, we just did another job with this system, and our operator noticed a little delay in between the outputs of the triple head to go as well. Less than a frame but noticable in fast movements.
I know that the MacPro (not the catalyst) has problems with latency between output number one and two. But from TH2Go this should work.
I also know that the spyder has a framesync option for the inputs, that option was switched off in that case (they noticed that after the show). We will do a full test setup next week to check these things out.
It´s strange to see things like these happens. We just bought a spyder system and we will use Catalyst as the background machine everytime.

And yes, for us here in Europe the limitation in resolutions of the TH2Go is a bad thing. Because we are playing almost all of our movies (when there is not enough time to do custom ones) in 25 Frames per Second. That means that all HD Resolutions of the TH2Go are not useable, because they are all 60 Hz and requiring 30 Frames.

One last Question: Did you play the 2 HD Feeds out of one system (so, did you use output one and two) ?

In the moment im waiting for a test version of the GForce Quadro FX5600, just to check out if the latency between the outputs could be solved that way. There is a Syncboard Option on the Nvidia Webpage for the FX5600 as well. To Genlock multiple systems. But the Driver is only WINDOWS!
But i know this is an expansive option. Quadro FX is around 3000$ and Syncboard around 1200$ i think. So you have to pay more bucks for your GPU than for a MacPro.

Scott, I will answer to your private mail later, because i will keep all the things regarding the latency problems public here.

Send some greetings to Andrea as well!
