Problem with second graphics сфкв !!!!!

Hello

You cannot use multiple graphics cards - only single graphics cards with multiple outputs

Hi,Nev!
Is there no solution? Video files play fine what is wrong with live video?

[Semillion]

Nev is correct, this cannot be done.
Video capture cannot be passed across multiple graphics cards.

You need a Matrox TripleHead2Go or a Datapath x4 to achieve more than 2x outputs from a pre 2014 (5,1 Generation or older) Mac Pro, using a single graphics card.

Not totally correct

With a AMD 7950 Card you can have more than 2 outs

do you know how this card compares to the GTX680 or Q4000
do you have any experience when connecting to 1 preferably 2 datapath's x4's

I swopped some of my Quadro 4000 to the AMD7950
You get better results, but I cant remember the figures.
GTX 680 is a bit lower in performance, and as the AMD drivers are within the system it seems to work smoother
Also some rental companys here in germany switched to the 7950 from Qaudro 4000.
Problem is that you can only get them in the US or UK at the moment

I only had 1 X4 connected to it... Sorry...
