Hello everyboby

we use catalyst on MAC pro 8-core with snow leopard, ATI HD4870.
we just buy a triplehead 2Go digital for work with 4 output but with LED WALL PANEL " STARFRAME STARWAY" .
then when we plug 3 monitor on the matrox DHG2O , we don't have problem but with the Led panel , we don't have output.

config ex:
MAC OUT1: MONITOR 1280x768 Mini PortMAC->DVI

MAC OUT2: MATROX TRIPLE HEAD DVI 3072x768
---> OUT 1 : MONITOR 1024x768
OUT 2 : LED PANEL 1042x768
OUT 3 : MONITOR 1024x768

then in this config we have only signal on out 1 and 3, the led panel is black and no signal.

Have you a Idee and can you help me.
Thanks a lot and sorry for my bad english, i'm french
