Despite all the connectors on you video card, all nVidia cards only allow 2 to be active at the same time. If you need more than 2 monitors at the same time, you can either use an AMD/ATI Eyefinity card or use two nVidia cards. The latter solution can be tricky, but since both of your suggested nVidia cards do NOT support hardware acceleration, you may be better off with a single AMD/ATI card. The alternative is to get two GTX 460+ cards and possibly a new PSU and more cooling. A third monitor is also possible with a firewire connection thru a camera/deck but only in SD and always without hardware acceleration.
Thanks for the suggestions.
I already have the NVIDIA 570 card, due to the certification of ADOBE.
So changing it to another card is costineffective.
Can you a bit specific on your comment of using another NVIDA card as driver for the 3th monitor. There are many discussions on the forum(s) on this subject, and mostly the use of a second (but from the same branche) videocards is often suggested. I will also look at te possibility you suggested to use the deck (JVC BR DV 600EA) as starting point.
I misread your mention of the GTX 570 and read it instead as a Quadro FX 570, hence my remarks. Sorry.
I would try to get a GTX 560 or even a GTX 550 as a second card, provided you can return it if it does not work as expected. They are the same generation as your current 570 and use the same drivers. Be sure that you activate the 570 as your CUDA card and use the other one only to connect your third or fourth monitor.
Thanks, I will try the 550.
One silly question, but as I am a common user and not well known with the technical aspects.
If the set up works, I expect that the three monitors give principally the same picture (clone). Drag and drop the menus in PPRO 5.5 you can easely make your own setiings for editingpurposes on the 2 basic editing monitoren. Thats what I already did.
But how does the 3th monitor knows, that it only should give the sourcemonitor in good quality. Which way should I prepair PPRO 5.5 that this will happpen.
